September brought in a change of weather; stormy wetter conditions set in along with cooler mornings. Earlier in the month, I was lucky enough to witness a mini murmuration of Starlings (Sturnus vulgaris) as they flew away from a storm that was rolling in. The commotion they produced made me look up; there were about 30 to 40 of them grouped together before they eventually headed off.
Hedgerow foraging has been mixed due to the dryness earlier on in the year. There are fewer conkers but the Horse chestnuts (Aesculus hippocastanum) showed signs of stress as the leaves began to brown off at the end of August. While there have been plenty of blackberries this year, most were smaller and dried up. Plus elderberries ripened a month earlier than usual. There have been plenty of walnuts and acorns though.
Fungi has begun to appear lately. One I spotted on an Ash tree (Fraxinus) was the Shaggy bracket (Inonotus hispidus).
Commonly found on deciduous trees, mostly Ash but also Planes (Platanus), Walnut (Juglans regia) and Apple (malus), it is inedible; attacking the trees heartwood, entering through a wound. It starts off with a velvety look (as seen in the photo) but eventually becomes brittle and black.
Now September has arrived, there is definitely an Autumnal feeling in the air. Similar to March, this month often has a transitional effect on me; especially once the Autumn equinox arrives on the 22nd. The nights are noticeably getting colder and drawing in. Over the past few weeks, some mornings have been misty and there has been a mixture of weather throughout the weeks; humid and stormy one moment and colder and sunny another. Spiders and their webs have become more visible, helped in part by morning dew, plus leaves are beginning to turn on some trees while autumn Cyclamen and crocuses (Colchicum autumnale) are starting to flower. I love September after the intense heat of August I long for a bit of relief.
On the allotment, autumn raspberries (Rubus idaeus) and apples are ready to pick along with pears, damsons (Prunus domestica subsp insititia),
Damsons ready to pick.
elderberries (Sambucus) and blackberries (Rubus). Conkers are falling now too, although the walnut and hazelnut harvests have passed.
Sweet chestnuts are almost ready to fall.
On the last bank holiday of the year (almost a month ago), I visited Minster-on-sea with my partner and his parents. It was an ideal day for walking along the beach searching for treasure, perhaps fossils, sharks teeth, sea glass, pieces of broken pottery and the occasional sea lego. Washed up along the beach were lots of Slipper limpets (Crepidula fornicata).
These limpets arrived on these shores from America via ships in the 1800s and thrived in the UK; especially southern England and Wales, where they have become a pest to muscle and oyster beds (competing for food and space). They are edible themselves.
It is usual to see individual empty shells, in fact they are found in huge numbers on beaches in the Solent. The common name of this sea snail refers to the appearance of an individual shell when it is viewed upside down; similarly the latin means small boot. When alive, these gastropod molluscs are rarely found alone (as shown in the photo above). Up to 12 Slipper limpets can be stacked together with the female, the largest and oldest, at the bottom; all the others are male or, in the case of the second from bottom, in the process of transforming into a female. When the one at the bottom dies and falls off, the next one up then becomes female. Further information on these fascinating creatures can be found in an article written by Nick Baker here.
The Slipper limpet isn’t the only snail that I noticed recently. I often get to see land snails but I noticed this beautiful orange coloured Brown lipped snail (Cepaea nemoralis) hanging around after a rainy morning. Snail shells can be very beautiful and I am intrigued by their structure.
Whatever your view on snails it’s hard to look at their shells without admiring the beauty.
I have become more aware of insects lately, mostly when cutting back perennials at work. Although I try to be careful as much as possible, occasionally I disturb a few. I always make a point of replacing or moving them to a safe place. Mostly it is ladybirds but I have also noticed a few other species, such as Common earwigs (Forficula auricularia) and the Rusty tussock (Orgyia antiqua) and Knot grass (Acronicta rumicis) moth caterpillars
Common earwigs feed on organic matter and like to hide away in dark areas of the garden (not in human ears).
Earwigs are useful garden recyclers.
Once eggs are laid, the females diligently clean them and constantly guards the nest only stopping when the young can fend for themselves. While the adults can nip humans and predators, it is only as a warning.
Caterpillars of the medium sized Rusty tussock moth can be seen between May and September.
The males and females of this moth, also called the Vapourer, look different from on another. The males are orangey-brown while the female has a more grey colouration and also lacks any significant wings; therefore it is only the males of this species that are active (mostly flying during the day). The young feed on broadleaf trees and shrubs in gardens and parks, as well as along hedgerows, heaths, moorland and woodland. The adult female and male moths can be seen here .
Knot grass caterpillars (see photo above) can often be found in late summer (and even as late as October in Southern Britain; although these are usually a second generation). Pupa of this moth survive the winter in leaf litter. The grey coloured adults (with a wingspan of 3-3.5 cms) can be seen from May through to September. The caterpillars can be observed on herbaceous or woody plants such as knotgrass (Polygonum aviculare), bramble (Rubus), hawthorn (Crataegus), common sorrel (Rumex acetosa), heather (Calluna), plantains (Plantago), docks (Rumex) and purple loosestrife (Lythrum salicaria). It makes sense therefore that this one was found nibbling on a raspberry leaf on the allotment. The numbers of this moth are declining and while they are still commonly found in gardens, heathland and grassland, it is thought that the species is becoming vulnerable. I was happy to share my raspberry plant with this caterpillar; raspberries are my favourite fruit but it certainly wouldn’t do any major damage. A photo of the moth can be seen on the UK Moths website.
Sadly the results of the Butterfly count for this year came out last week. They confirmed people’s suspicion that it hasn’t been good for butterflies and moths (as well as bees). Many butterfly and moth numbers continue to fall, and significantly so from previous years results, due to a variety of factors including the cold wet weather we’ve experienced this year. Further information can be found on the butterfly conservation website here.
Thankfully last Friday, I witnessed a wonderful sight during a warm sunny afternoon. A huge area of ivy in full bloom was covered in so many bees that it stopped me in my tracks. I stood nearby and listened to the wonderful buzzing sound, it was so relaxing. There were so many Ivy bees (Colletes hederae) alongside buff tailed bumblebees (Bombus terrestris) and honey bees (Apis mellifera) visiting the ivy flowers. It was the first time I was able to definitely identify ivy bees which was amazing (see below).
First recorded in the UK in 2001, Ivy bees are becoming more common. They look very similar to honey bees but can be distinguished by the stripes on their abdomens; the bright yellow stripes are distinctly separate from the black ones than they are with honey bees. Unlike honey bees these are solitary, however there can be lots of nests close to one another and these bees will forage together when opportunity allows. As their name suggests, they feed predominantly on the nectar of ivy flowers and therefore their appearance coincides with this plant flowering (between September and November). I have been searching for a definite sighting of these bees for years and finally I have been rewarded for my patience.
I’ve found more galls, over the last few weeks, this time on the ground surrounding a few Pedunculate Oaks (Quercus robur).
These galls remind me a little of the Facehugger in the Alien film franchise.
They are produced by these trees as a result of the Knopper gall wasp (Andricus quercuscalicis) laying young in the acorns. As with the Oak apple gall wasps (Biorhiza pallida) mentioned in a previous post ‘Relaxing Evening Birdsong’ , they are not detrimental to these majestic trees and don’t appear on many of the fallen acorns. Interestingly each generation of the wasp will change between sexual and asexual each alternate year.
I also saw my first Goldcrest (Regulus regulus) in a cypress tree near the beginning of the month. Although I could see the silhouette of this tiny bird moving around the top of the tree. I was only able to identify it using the Chirp-o-matic app on my phone, due to its loud singing. The Goldcrests song can be heard on the Woodland trust website here , where you can also see a photo of this diminutive bird. I wish I could have viewed it at closer range, then I would have been able to see the wonderful plumage on the crown (yellow for females and orange for males). The Goldcrest is the smallest bird in Britain, even smaller than the Wren (Troglodytes troglodytes). Hold a 20 pence piece in your hand, and you will have an idea of the birds weight (just 5 grams). They inhabit mixed woodland and conifers along with parks and gardens. The numbers of our resident birds increase with the migration of others from Scandinavian countries during the winter. They feed on insects and other invertebrates. It is always lovely when I am still able to witness new things in nature like this. It gives me a buzz, allowing me to learn through research.
For the last couple of weeks conkers and sweet chestnuts have begun to fall, there isn’t a big harvest, neither are there lots of acorns or beech masts. However 2020 was a mast year (where trees produce bumper crops) so reduced harvests this time isn’t too surprising; Mast years only happen every five to ten years. However the low numbers could also be due to this years cold damp spring impacting bud development and fertilization, especially with wind pollinated trees. This issue is discussed further in an article by the Woodland Trust see Nature’s Calendar.
It has been lovely to notice Boston ivy (Parthenocissus tricuspidata), along with Virginia creeper (Parthenocissus quinquefolia) develop their bright red autumnal colour. They are so vibrant in the low autumn sunshine. I’ve also noticed the small beginnings of autumn leaf colour in many trees too.

Now that October has arrived, Cyclamen (Cyclamen hederifolium) and Crocuses (Crocus speciosus) have sprung up alongside Fungi in a few lawns. I noticed a waxcap commonly called the Witches hat (Hygrocybe conica) as well as Lilac fibrecaps (Inocybe geophylla var. lilacina); both resembling Gemstones standing out amongst the grass.
Witches hat waxcaps are so called because they look like witches hats when they blacken with age.A Lilac fibrecap
I also saw another fungi in one lawn, possibly a Blusher (Amanita rubescens), although the identification was difficult so I’m not entirely sure.
Plantlife run Waxcap watch from the 13th September. The charity want to discover previously unknown waxcap grassland sites, uncover habitat conditions and give better protection for them in the future. More information about this survey can be found here.
Something else I observed while weeding a gravel path at work was a Lunar underwing moth (Omphaloscelis lunosa).
This night flying noth had been hiding under some dandelion leaves.
Lunar underwing moths fly between August and October and their pupae overwinter in long grass which they will feed on when they become caterpillars. I managed to re-home this one under a nearby shrub.
I am feeling cozy, sitting on the sofa, as I reflect on last weeks observations on a dark evening.
Along with the earlier sunsets, fresh mornings have begun to take hold too. I have been noticing a lot of changes occurring with trees throughout the week. Their leaves are turning autumnal and I have been able to pick fresh apples as I work. Lots of conkers are falling around the bus stop too.
One of the apple trees with lovely sweet apples is pictured below. There were other trees with Russet and Cox apples.
The Rowan tree outside my home continues to have Blue tits (Cyanistes caeruleus) feeding on insects. Plus I have also seen a Robin (Erithacus rubecula) and two Long tailed tits (Aegithalos caudatus) eating insects on it’s branches, along with a Blackbird (Turdus merula) feasting in the berries.
Mr Blackbird wasn’t camera shy.
I still saw Small white (Pieris rapae), Red admiral (Vanessaatalanta) and Painted lady (Vanessa cardui) butterflies as they took advantage of the late flowering perennials.
On Wednesday I noticed a Painted lady butterfly as well as a Common carder bee (Bombus pascuorum) visiting some Ceratostigma willmottianum which is still blooming while the leaves are turning red.
Some plants have been flowering all summer, such as Geraniums and Verbena bonariensis, and now bloom alongside Sedums, Asters and Autumn crocus (Colchicum autumnale) painting gardens in muted colours.

Cutting back faded perennials was one of last weeks jobs which meant I disturbed a lot of Seven-spot ladybirds (Coccinella septempunctata). So I spent quite a bit of time rescuing them from garden waste bins too.
Lastly, as I walked home late on Wednesday, I ended up seeing a beetle walking across the path in the moonlight and enjoyed the view of the Waxing gibbous moon amongst the clouds.
I have begun to notice a chill in the mornings as the nights grow colder. I love the promise of Autumn. It doesn’t quite feel autumnal yet (especially as the weather has warmed up again this weekend) but some changes are occurring. Conkers and beech masts have started dropping and fungi are appearing in some lawns. A couple of times I have come across fairy rings; in both instances the Marasmius oreades fungi was the cause (sadly no magical elvish, fairy or pixie dancing).
The week continued with more observations of Painted lady (Vanessa cardui) butterflies. On Monday there were two visiting a Buddleja bush along with a Small tortoiseshell (Aglais urticae) and a Large white (Pieris brassicae).
Then on Friday, in different gardens, more were flitting about. On one occasion, during the morning, I saw a Painted lady on a Ceratostigma willmottianum.
In the second half of the week I noticed more butterflies including a Green-veined white (Pieris napi) on Verbena bonariensis
and a Small tortoiseshell visiting an Erysimum ‘Bowles’s Mauve’.
Throughout last week I saw lots of pollinators busily collecting nectar and pollen.
On Monday I noticed lots of small flies and Buff-tailed bumblebees (Bombus terrestris) pollinating Marigold (Tagetes) flowers. Perhaps they are enticed by their overwhelming aroma which even I found hard to ignore.
Then on Wednesday there was a Common carder (Bombus pascuorum) bee flying between Nandina domesticas and several Agapanthus africanus.
On Friday while working near some Hebe ‘Great Orme’ there were lots of honey bees (Apis mellifera) as well as a Hornet mimic hoverfly (Volucella zonaria).
Another interesting thing I noticed last week was a Red campion (Silene dioica) plant growing on an old moss covered log.
With no soil surrounding its roots clearly it was receiving sufficient moisture and nutrients from this unusual source. It has been flowering healthily all summer but I hadn’t realised it had been relying on the log for its growth until then. I found this plants ability for survival amazing and will closely watch its development.
Lastly I have been aware of how wonderful hardy Fuchsias (Fuchsia magellanica) are currently looking. Although I don’t see pollinators visiting the flowers, there have been a couple of times, in the past, when I have seen Elephant Hawk-moth (Deilephila elpenor) caterpillars feeding on Fushia plants. (See Elephant Hawk-moth).
These caterpillars also eat Himalayan balsam (Impatiens glandulifera) and Willowherbs including Enchanter’s nightshade (Circaea lutetiana) and Rosebay willowherb (Epilobium angustifolium). This beautiful pink and olive green moth flies at night and therefore feeds on Honeysuckle (Lonicera).
Across the way from this hardy Fushia there was a Honeysuckle growing along the wall so it would have been a fantastic place for these moths to inhabit. Unfortunately I didn’t come across any Elephant Hawk-moths this year but hopefully I will in years to come (and I am sure it will feel magical).
