With May finally here, spring is now in full swing. Lots of things are growing on the allotment from seedlings to fruit, even the Rhubarb is almost ready to pick.
During a woodland walk, on the Easter weekend, I observed the first Speckled wood (Pararge aegeria) butterfly of the year. Plus local ornamental Cherry trees (Prunus) began their spectacular show at the same time; later joined by the flowers of the Hawthorn (Crataegus) , Rowan (Sorbus) and Horse chestnut (Aesculus hippocastanum).
Over the last few weeks, more wildflowers have started to bloom, including Buttercups (Ranunculus), Stitchwort (Stellaria), Ground-ivy (Glechoma hederacea) Honesty (Lunaria annua) and Hedge garlic (Alliaria petiolata) along with Cuckoo flower (Cardamine pratensis).

Another butterfly that began to emerge recently is the Orange-tip (Anthocharis cardamines). Hedge garlic and Cuckoo flower are important food sources for Orange-tip caterpillars, so it is lovely to think these butterflies will be laying eggs on the plants I’ve noticed to ensure future generations; the verge not being mown, allowing both plants to develop, enabling this.
The ‘No mow May’ campaign is back this year. Encouraging us to avoid mowing lawns in order to encourage a wide variety of wildflowers to bloom (including rare ones), thus increasing the availability of pollen and nectar for pollinators as they start to emerge (along with helping butterfly populations, as discussed above). After several years of this campaign together with the every flower counts survey, improvements in wildflower growth have been recorded, as people report their sightings taken at this time. An article from the Plantlife charity discusses their findings in more detail here.
Even leaving the humblest of flowers to flower on lawns, like Dandelions (Taraxacum), Daisies (Bellis perennis) and Buttercups helps.
What a mixed bag of weather we’ve had in the UK recently. It seems strange experiencing the current dry, warm weather given the snow, frost and april showers we had during the previous weeks.
Deciduous trees are turning green, as leaves unfurl and wildflowers continue to bloom. Snake’s-head fritillary (Fritillaria meleagris), Speedwells (Veronica), White Dead-nettle (Lamium album), Red Dead-nettle (Lamium purpureum), Yellow archangel (Lamium galeobdolon), Forget-me-nots (Myosotis) and Cowslips (Primula veris) are all flowering at the moment, with English Blubells (Hyacinthoides non-scripta) beginning to open up too.

Last week I caught a glimpse of a blue butterfly, my first sighting of the year, most likely a Holly blue (Celastrina argiolus). I also found another Red kite (Milvus milvus) feather as I worked last Tuesday (see below).
Even Tadpoles have begun to emerge, including in the pond we have near our plot on the allotment; hopefully they will help keep the slug and snail numbers down this year.
Slugs and snails have been in the news a lot this month because the Metaldehyde slug pellets ban has finally come into force in the UK. Perhaps we could view these creatures in a different way, after all they do good in nature; we can’t blame them going for an easy meal of soft tender leaves which just happen to be our prized plants. Interestingly only a small number of the 44 species in the UK are responsible for the damage we experience in gardens while the others feed on dead organic matter. I read an interesting article by Dr Andrew Salisbury, from the RHS, in The Guardian on this subject.
On my allotment I find wool pellets, copper barriers and cloches are helpful; along with growing seedlings on in pots before planting them out. Transplanting larger, stronger plants is better as they are able to withstand any damage, I also spend time collecting slugs and snails from hidden damp dark places and moving them to an area far away where they will cause less damage to crops. Encouraging predators (frogs, toads, hedgehogs, birds, slow worms (Anguis fragilis) and ground beetles) is always a great idea too, along with not having areas for them to hide near vulnerable plants.
A biological control that can be used, for slugs only, are Nematodes (Phasmarhabditis hermaphrodita). Watered into the ground these eventually kill the slugs as they infect them with bacteria once they’ve entered the slugs body. I have never gone for this option as I find the other measures suffice.
The other option is to grow plants which slugs and snails do not eat. Ones I’ve noticed they avoid include Ajuga, Aquilegia, Digitalis, Fuchsia, Geum Penstemon and Pulmonaria (further examples can be found on the internet).
The full moon in March, is commonly named the Worm moon in the UK as it coincides with the appearance of worm casts. Worm casts begin to appear as the soil warms up enabling worm activity on the top layers of soil. They are often the bain of those who love prestine lawns but easily dealt with by raking, to break them up before mowing (thus preventing small bare soil patches that encourages wild flower and moss growth). However, apart from this slight inconvenience for some, obviously worms are hugely beneficial creatures in nature. They help create a healthy soil ecosystem, aid the decomposition of organic matter, improve soil structure and increase available nutrients for plants.
In the UK there are 27 species of earthworm, which can be categorised into three types, Anecic, Endogeic and Epigeic. The latter are surface dwellers which breakdown vegetation lying on the ground. These small, usually red worms (or stripey in the case of Tiger worms- Eiseniafetida) are often seen in composts. The other two types of worm burrow. The most commonly seen in gardens are the Anecic worms (which pull leaves down into the soil). These large reddish brown worms are responsible for worm casts in lawns and burrow vertically while the paler coloured Endogeic worms burrow horizontally and live further down in the soil. More information on earthworms can be discovered here on the Earthworm Society website.
Another notable date that occurred last week on the astronomical calender (in the northern hemisphere) was the Spring equinox. The moment in March when day and night length are equal and officially the first day of spring. (Meteorologically this already occurred on the first of the month). Whichever date you prefer to observe as it’s start, Spring has definitely arrived here in the UK.
Nature seemed to celebrate the arrival of Spring with several days of unseasonably warm weather, together with the appearance of more butterflies, with Peacocks (Aglais io), Commas (Polygonia c-album) and yet more Brimstones (Gonepteryx rhamni) fluttering about, together with lots more bumblebees. So far I have seen lots of Buff-tailed bumblebee (Bombus terrestris) and a few Red-tailed bumblebees (Bombus lapidarius). Even Seven-spot ladybirds (Coccinella septempunctata) came out of hiding last week.
More trees are blossomimg too. Magnolias, Camellias, Forsythia, Gorse (Ulex) and Willows (Salix) are flowering now, joining the Blackthorn (Prunus spinosa). Plus yellow and green carpets of Lesser Celendine (Ficaria verna) have been popping up everywhere.
I can’t believe March has arrived already. Blackthorn (Prunus spinosa), Sweet violet (Viola odorata) and Daffodils are in full bloom.
It wasn’t so long ago that we had the stormy weather and Snowdrops were at their best; the year seems to be advancing in leaps and bounds now.
The temperature last Thursday reached 16°C which encouraged butterflies to flutter about. I noticed several Brimstones (Gonepteryx rhamni) as well as the Red admiral (Vanessa atalanta) below.

Along with these beautiful sightings, there were a couple of amazing nature experiences that particularly stood out over the past few weeks.
The first was due to the recent storms. While clearing up tree debris a few days later, I found a Red kite (Milvus milvus) feather which had blown to the ground. I have since added it to my version of a nature table (a vintage printing tray) along with my other treasure finds.
I love the shape, colour and pattern of this Red kite feather.
The second took place last Wednesday. While carefully tidying up another garden, to allow for the new spring growth which is already appearing, I noticed a young male Blackbird (Turdus merula) following and closely foraging next to me, just like Robins (Erithacus rubecula) often do in gardens. At one point, it appeared to watch me as I worked (seemingly unphased as I kept my movements to a minimum, so as to not alarm him). Eventually it moved further away but started to make a low repetitive ‘pok pok’ call, at both me and my colleague who was a short distance away (presumably thinking we were predators). This interactive experience was particularly moving; I am used to Robins being close by and making themselves known but never a Blackbird before. The call I heard the blackbird make can be heard on the Sussex Wildlife Trust website.
As another month rolls on, an initial glance may suggest that nothing is changing. Bare trees and quiet gardens with cold weather still nipping at fingertips and noses still persist, while sunny days bring glorious colourful skies.

However, upon closer inspection small changes can be seen. The striking yellow of Winter aconites (Eranthis hyemalis) as well as delicate Early crocuses (Crocus tommasinianus) are beginning to bloom alongside the snowdrops (Galanthus).
The tiny red female flowers of Hazels (Corylus) have opened joining the male catkins. Plus, Blackthorn (Prunus spinosa) buds are ready to burst open (in fact on one walk, I saw a single flower already blooming).
I even witnessed a Red admiral (Vanessa atalanta) visit a flowering Mahonia on one sunny day; clearly making use of the milder weather before sheltering once again.
However the main focus of my attention, over the past few weeks, have been birds.
In one garden, I discovered a lovely little nest, from the previous year, in a shrub. Upon investigation I discovered it was either a Goldfinch (Carduelis carduelis) or Greenfinch (Chloris chloris) nest (most likely the former); it can be seen below.
I also saw a Lesser spotted woodpecker (Dendrocopos minor) perched on a tall tree in the distance. I was able to follow the sound of the drumming to watch it move around the trunk before flying off. Given the length of drumming and location of the red on it’s crown I was able to identify it as a male Lesser spotted woodpecker.
Then later in the week, while pruning roses, I watched a Wren (Troglodytes troglodytes) forage around the base of a hedge; I managed to film it briefly before it disappeared fully into the undergrowth.
I am currently reading ‘The Wren: A biography’ by Stephen Moss.
This charity shop find is a fascinating read. Chapters are set out month by month, each concentating on an aspect of a Wrens life. Included alongside facts about the Wren, are their involvement in human history, culture, literature, art and folklore together with beautiful illustrations. The chapter entitled February, for example, focuses on courtship and population. As with other books written by this author, such as ‘The Robin’, this book is definitely worth emmersing yourself in.
Lastly, once again I partook in the Big Garden Birdwatch. My results this year were- 7 Starlings (Sturnus vulgaris), 4 Magpies (Pica pica), 2 Bluetits (Cyanistes caeruleus), 2 Blackbirds (Turdus merula)- a male and female, 2 Wood pigeons (Columba palumbus), 1 Dunnock (Prunella modularis) as well as a Carrion crow (Corvus corone).
Although there weren’t any major surprises in what I saw, it was lovely that the Dunnock made an appearance (usually I only get to hear them). However the Red Kite (Milvus milvus), Ring-necked parakeets (Psittacula krameri), Great tit (Parus major) and Robin (Erithacus rubecula), that I regularly observe, all decided to have a lie in the previous weekend, most only making an appearance once my chosen hour had ended.
It definitely feels like late summer now. Nights are noticeably drawing in, the sun is lower and my spidey senses have noticed a change in the air too.
The highlights of last week were seeing a Painted Lady (Vanessa cardui) on a Buddleja and noticing the harvests developing.
Autumn, my favourite season, is nearly here. The apples at the allotment are coming along nicely, almost ready to eat, along with the ripening blackberries. Plus hazelnuts and walnuts can be picked soon too.
Rowan berries have ripened now, their beautiful red colour showing through the green foliage. Last Thursday I noticed a female blackbird pick some before flying off with them.
It’s also been lovely to see my resident family of Blue tits on the Rowan tree (Sorbus), as I enjoy breakfast before my days work.
These small moments bring me so much joy and are a fantastic way to begin the day. I am grateful for natures restorative ability. Finding solace in it helps ground me while enabling me to remain in the moment and appreciate the small things. This time of year, when nature starts to slow down, also reminds me to take things more easily too. I do love this time of year. For me, the transition into Autumn, is a time of contemplation and preparation for the future.
Over the last few weeks Buddleja have been in flower, encouraging butterflies to visit and making them more visible. I have begun to notice Red admirals (Vanessa atalanta) and Peacocks (Aglais io) alongside Large (Pieris brassicae) and Small white (Pieris rapae) butterflies.
Having some time off work enabled me to take more walks. In my local woodland park I started to see a lot more Commas (Polygoniac-album) and Small heath (Coenonympha pamphilus) butterflies too. On a few occasions they flitted around me as I stopped to watch them; an absolutely joyful experience, almost like they were interacting with me in their own way.
Thankfully in the two weeks, I managed to venture further afield. On one occasion, I saw a Ringlet (Aphantopus hyperantus) butterfly while visiting an Arboretum in Herefordshire.
Woodlands are their habitat and they can be seen during July and August. The Caterpillars of this butterfly feed on various grasses, such as Tufted Hair-grass (Deschampsia cespitosa), Common Couch (Elytrigiarepens), and other meadow grasses (Poa spp.).
Spending some time away on holiday gave me the chance to explore other environments, including those next to water, thus enabling me to notice different wildflowers.
One walk took me past a canal. Water mint (Mentha aquatica) and Purple Loosestrife (Lythrum salicaria) were growing all down the canal edge.
Water mint
Both plants grow in shallow water and boggy conditions so are often found in fens and marshes as well as along the margins of ponds, streams, rivers and of course canals, as I discovered. They require habitats with full sun or dapled shade to bloom and are great for pollinators. Water mint flowers from the beginning of July up to November while Purple loosestrife only blooms between June and August. Purple Loosestrife can be visited by insects with long tongues and particularly enjoyed by butterflies and Red-tailed Bumblebees (Bombus lapidarius). It is also eaten by caterpillars of the Small Elephant Hawk-moths (Deilephila porcellus).

As well as butterflies there were several dragonflies and damselflies, including this Blue-tailed damselfly (Ischnura elegans) dancing over the water.
This Blue-tailed damselfly was seen resting on a nettle leaf.
However, most of the bees I saw on that walk were interested in the plant I encountered at the first lock, Himalayan balsam (Impatiens glandulifera).
While the lock was completely swamped by this plant, it was only section I saw it in. It’s the first time I had come across Himalayan balsam, although I know of its reputation.
The pretty flower of the Himalayan balsam is popular with pollinators, especially bees. Here a bee is seen climbing into the flower to obtain nectar and pollen.
First introduced into the UK in 1839, from the Himalayas, this plant soon escaped formal gardens and naturalized in the wild becoming a nuisance in waterways. It grows fast and can become invasive very quickly as, up to 800 seeds from each pod, explode as far as 7 meters from the parent plant and even travel downstream. It isn’t long before a thicket is created where the plant out-competes other species to reduce biodiversity, cause erotion of riverbanks and affect water quality. All this means it is considered a weed in waterways and often removed by work-parties whenever possible. In fact it had been previously cleared from a lot of this canal. Control methods include pulling and cutting before they get a chance to set seed. It can take a few growing seasons before control over this plant is established. Management of this plant is mentioned under schedule 9 of the Wildlife and Countryside Act 1981. Interestingly, in Hertfordshire, control of this plant involves collection of the flowers to produce pink Gin (further information can be found at Herts Wildlife Trust).
The following week I visited a beach in Kent, it was so relaxing to hear the sounds of the seaside. One plant I noticed growing amongst the rocky area near the shingle was Alfalfa (Medicago sativa).
I know this plant as a green manure on allotments and gardens, adding nitrogen to soil for crops the following season. It’s also used as silage for livestock in agriculture plus alfalfa sprouts are used in some cuisines. I have never seen it in the wild or even flowering. There wasn’t a great swathe of it so clearly the plants were due to the odd escapee into the wild; perhaps a few seeds having blown there or been disposed by a bird. It was certainly good for local pollinators.
The last few weeks have been opposites in terms of the weather. A wet previous week turned into the hottest of the year so far (with no relief overnight). Although too hot for my comfort, it was perfect weather for butterflies, and a great start for the Big Butterfly Count. Finally I was beginning to witness an increase in the amount of butterflies. I was getting worried this years reduction in butterfly sightings (due to the cold spring and wet summer experienced in 2021 up to this point) would continue. However by the end of the first week, I saw a Speckled wood (Pararge aegeria) and a Brimstone (Gonepteryx rhamni). Then, while on a walk around my local woodland park (early on the following, sunny and very warm, Sunday morning) I witnessed lots of butterflies making the most of the sunshine.
In one open area of the park, the grass had been allowed to grow, with many species of wildflower blooming amongst it. One of the plants I saw was Common centuary (Centaurium erythraea) which blooms between May and October. Overshadowed by the other wildflowers and grasses, initially this shorter plant was difficult to spot; in fact had it not been next to a mown walkway, I may not have seen it. Thankfully it’s pink and yellow colouration stood out enough, from the more muted colours surrounding it, as I wondered past trying to identify butterflies.
Common centuary represents delicacy and felicity in the Victorian Language of Flowers.
This plant is found in a many places, from heathlands and woodlands to cliff tops and quarries. A natural meteorologist, the flower closes when the weather is dull and damp to reopen once the weather brightens up. While I’m not sure this is a practical weather indicator to use (when a simple observation of the sky, in that moment, will give you the information you require) it’s a pretty cool reaction to weather conditions.
There were many butterflies flitting about on that Sunday morning. Most prominent were Gatekeepers (Pyronia tithonus), Small skippers (Thymelicus sylvestris)

and Small heath (Coenonympha pamphilus) butterflies; probably due to the grass being allowed to grow fully. All these species of butterfly are associated with grassland and their caterpillars feed on grasses. Marbled white (Melanargia galathea) caterpillars also feed on grasses while the adults feed on many purple coloured flowers, including knapweeds; so it was lovely to see one of these butterflies flying around the meadow too.
Another plant that was growing amongst the long grass was Ragwort (Jacobaea vulgaris). This is a favourite nectar source of the Gatekeeper butterfly, along with other plants including Bramble (Rubus fruticosus), Wild marjoram (Origanum vulgare) and Wood sage (Teucrium scorodonia).
Ragwort is great for many pollinators, including these Small heath butterflies.
I also got to see another insect with a strong connection to Ragwort, a caterpillar of the day flying moth, the Cinnabar (Tyria jacobaeae).
This wasn’t the only caterpillar I noticed. Earlier in the week, I saw a caterpillar of the Knot grass moth (Acronicta rumicis), seen below on a bramble leaf.
This caterpillar will be part of this years second brood, the adults of which appear in August and September. The Caterpillars have a varied diet, eating a wide range of herbaceous plants; this one clearly eating out (and pooping on) bramble. The photo of the adult moth can be seen at Uk Moths.
On the eve of the Summer solstice I love to go to sleep early with my curtains open so I can wake up naturally and see the sunrise; it helps me align with the seasons and appreciate nature in a different way. This year I awoke at 3:50am and immediately opened the window so I could enjoy the dawn chorus. Initially the predominant birdsong was that of Blackbirds (Turdusmerula), occasionally punctuated by the calls from a Wood pigeon (Columba palumbus), a murder of very vocal Carrion crows (Corvus corone), along with a male Pheasant (Phasianus colchicus) in the distance too. The crescendo came around 4:10am but it wasn’t until finally at 4:42am, when things had quietened, that I heard a few more birds singing. There was a lone Dunnock (Prunella modularis) and then a Greenfinch (Chloris chloris) at about 4:50am; followed much later by Blue tits (Cyanistes caeruleus) which I observed in the Rowan (Sorbus) tree nearby.
It’s interesting to notice an order to the bird song. Blackbirds are the first to be heard, almost like they are an alarm call for the other songbirds; clearly eager to catch the worms.
I also learnt another birdsong last week, heard around midday on Thursday. Hidden somewhere amongst the treeline next to a field, was a Common Whitethroat (Curruca communis); the song can be heard here on the RSPB website.
This warbler visits the UK from Southern Africa (from countries south of the Sahara) between April and October. Once the males arrive on these shores, they will establish territories and build nests for prospective partners (approximately ten to fourteen days before the females arrive).
These birds are about the same size as Great tits (Parus major) and named after the white plumage on their throats. Males can be differentiated from female due to their grey heads. They feed on insects as well as fruit and berries later in the year.
After being concerned that I wasn’t seeing many butterflies and ladybirds the previous week, last week it finally became warm and sunny enough for them to venture out once again. It was lovely to witness a couple of Small tortoisehell butterflies (Aglais urticae) along with some bumblebees visit a Scabious plant in one garden.
Plus there was a loveliness of Seven-spot ladybirds (Coccinella septempunctata) at the allotment, hunting down on all the aphids which also appeared.
Cooler temperatures and very wet weather meant that insect observations were few and far between last week.
In sunnier moments, bees were still visible but I haven’t noticed many moths, butterflies or ladybirds recently; I do hope that changes soon.
However there were a few momentous insect observations last week. I discovered a Mining bee nest on the allotment. As there was an Ashy mining bee (Andrena cineraria) on the plot last year then it could be evidence of another one making its home there.
The other insect, one I got to learn about later in the week, was a stunning parasitic wasp; possibly an Amblyteles armatorius (however identification is difficult to be completely certain).
If it was an Amblyteles armatorius then it’s hosts can be several species of moth caterpillar, such as the Yellow Underwing (Noctua pronuba).
The yellow and black parasitic wasp was 15mm in length (antennae included) and is often seen in June; although there is a second generation later in the year too. Adults can be noticed feeding on pollen from plants with umbellifer flowers such as Cow parsley (Anthriscus sylvestris) or Hogweed (Heracleum sphondylium). There was Lovage (Levisticum officinale) in flower in the garden where the parasitic wasp was noticed, so perhaps it had visited that before flying off to find another plant.
