The Long Wait

I have been watching a wild flower grow, in the small garden that I look after in front of my flat. Initially unable to identify it (as I didn’t recognise the foliage) I patiently waited throughout autumn and winter to see what emerged. Then in late spring it developed stalks and flowerheads enabling me to see it was a Field scabious- (Knautia arvensis).

This perennial is blooming now. Bees are loving the flowers.

Field scabious is usually found in places such as grassland, meadows, grassy verges and hedgerows. This self set is obviously enjoying similar conditions in my little plot; thriving in an area against a brick wall with dry, partially shady conditions. It is wonderful to see it attract so many beneficial insects so am happy for it to remain where it is.

The allotment is coming on leaps and bounds. The strawberries (which rarely make it home) were a sweet reward as I watered daily through the recent heatwave and continue to ripen. The Blackflies on the Broad beans were eventually joined by seven spot (Coccinella septempunctata) and Harlequin (Harmonia axyridis) ladybirds, together with lots of their larvae; proof that if you leave pests, predators will appear to deal with them; nature really is wonderful.

The recent higher temperatures have encouraged butterflies to fly around. Lately I have seen Small tortoishells (Aglais urticae), Peacocks (Aglais io), Marbled whites (Melanargia galathea) and Speckled woods (Pararge aegeria).

Also on one sunny day last week, while eating lunch outside, I heard a bird song that I didn’t recognise. I recorded it on the Chirp-o-matic app (the name makes me think of Wallace and Gromit) to discover that it was a Yellowhammer (Emberiza citrinella). The rhythm and length of notes makes it sound like they’re saying ‘a little bit of bread and no cheese’. In fact this phrase is used by birders to identify it by the song alone and can be heard on the RSPB website.

Unfortunately I couldn’t see the bird which was a shame as I would have loved to see its yellow plumage. Part of the bunting family, both males and females have yellow colouring mixed with some brown (the males can be distinguished as they are more vibrant). These birds are currently on the red list for UK conservation status and therefore
Protected by The Wildlife and Countryside Act 1981. Found on farmland, they
eat seeds, insects, worms, caterpillars, spiders and snails and weigh in at about 25-36g weight (a similar size to a sparrow).

To encourage yellowhammer numbers, the RSPB has produced information for farmers so they can take action to help these birds; However the actions can be applied by anyone living near farmland, and can be found here.

Worm Moon Shining

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- Eisenia fetida) 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.

Relaxing Holiday Adventures

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 (Polygonia c-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 (Elytrigia repens), 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.
