🎵The Heat Is On. 🎤 🎹🎷🎶

“Tell me can you feel it, tell me can you feel it, tell me can you feel it, the heat is on…”

The 80’s song from the Beverly Hills Cop soundtrack with Glenn Frey’s voice, synthesizer and saxophone was my earworm as the temperature soared last week. The temperature increased to around 27°C mid week, which meant lots more insects ventured out as it felt like summer.

I was happy to see my first Red admiral (Vanessa atalanta) butterfly of the year, however my main observations were bees including the Red-tailed bumblebee (Bombus lapidarius) and Honey bees (Apis mellifera).

Honey bees visited Nepeta.

Another bee I started seeing last week was the Tree bumblebee (Bombus hypnorum). I noticed a nest inside a compost bin as I emptied grass clippings from the mower bag.

I have seen Tree bumblebees nest in bird houses before but not under compost. I made sure I avoided tipping grass onto their home and used the next bin along. I couldn’t help watching them for a little while as I stopped for a breather on the very hot Wednesday.

Moths were prominent throughout the week too. Unfortunately Box tree moth (Cydalima perspectalis) caterpillars and the signs of heavy infestation (foliage that had been eaten and covered with webbing) was noticeably present in several gardens. Therefore, I spent lots of time picking them off buxus topiary and informing clients to keep an eye out for them as well. For more information on this pest see the RHS website.

I discovered this years first sighting of a Silver Y (Autographa gamma) moth.

This immigrant is one of the few brown moths I can identify easily, mostly due to the clear y markings on it’s forewings but also because of their size and shape. This is a day and night flying moth which can be observed visiting flowers to obtain nectar.

However my most exciting moth sighting was the Lime hawk-moth (Mimas tiliae).

This spectacular large moth is night flying. It’s wingspan is 4.6-7.8cms and it can be found in broadleaf woodland, parks and gardens between May and July. I accidentally disturbed it as I pruned some shrubs under a Lime (Tilia sp.) tree. Thankfully it didn’t seem bothered by the disruption and it was carefully placed back near the lime tree. While adult moths of this species don’t feed, the caterpillars do. Once they have emerged from overwintering pupa, the caterpillars will eat Lime, elms (Ulmus sp.), Alder (Alnus glutinosa), Downy Birch (Betula pubescens) and Silver Birch (Betula pendula), Plane (Platanus x hispanica) along with some Cherry cultivars. This was the first Hawk-moth I have ever seen. There are a few that exist in the UK. The nearest I came to seeing one before was observing caterpillars of the Elephant hawk-moth (Deilephila elpenor) eating away at some Fuchsia. For more information on these Hawk-moths see the Butterfly Conservation website (Lime hawk-moth and Elephant hawk-moth)

I also saw hoverflies. I am still learning about these insects and learnt another one last week.

The photo above shows a Narcissus bulb fly (Merodon equestris). The maggots eat away at the centre of bulbs from the Amaryllidaceae family. However even though the maggots are a pest, the adult hoverflies are pollinators.

A Magical Week

Posted on by BITM

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).
