The Heat Is On. 🔆🌡️⛈️☔

Posted on by BITM

The weather last week was a mixed bag. Sunshine with the temperature rising into the thirties, fantastic storms and then dull days of rain. Thankfully it is a little cooler now; while I enjoy the sun, I wilt in muggy heat.

Given the weather there were still lots of butterflies around, mostly Peacock (Aglais io), Red admiral (Vanessa atalanta) and Small white (Pieris rapae). Unfortunately I haven’t managed to capture photos of any of these as they didn’t remain in situ for long. I see many white butterflies flit past me. It can be difficult to say if they are Large white (Pieris brassicae), Small white or female Orange tip (Anthocharis cardamines) butterflies because they disappear before I can identify them.

Happily I was able to photograph one butterfly on a Buddleia on Wednesday. The combination of the pattern in the underside, orange colouring I saw on the upper wings, together with the wing outline means the butterfly in the photo below is a Comma (Polygonia c-album).

Their Caterpillars usually feed on the Common nettles (Urtica dioica) but also Elms (Ulmus), Hops (Humulus lupulus) as well as Willows (Salix). Peacocks often visit Buddleia too. The Common Nettle is also the favoured food of Peacock Caterpillars; although they have been recorded feeding on hops and small nettle (Urtica urens) as well. As the common nettle is the favourite food of both Comma and Peacock caterpillars, what better reason is there for allowing some nettles to grow in a garden?

There were other observations last week too;
– a Harlequin ladybird (Harmonia axyridis) on some Lesser Burdock (Arctium minus),

– a Scalloped oak (Crocallis elinguaria) moth,

The caterpillars of these moths feed on honeysuckle (Lonicera), heather (Calluna vulgaris) and broadleaf trees like Oak (Quercus) and Birch (Betula).

– plus a Long hoverfly (Sphaerophoria scripta), whose larvae feed on aphids, and a Common green bottle fly (Lucilia sericata) on a Potentilla plant.

Capturing the Common green bottle fly was accidental but it worked out really well. In the sun its glistening metallic colouring is highlighted against the yellow Potentilla flowers. Their maggots feed on dead tissue so their appearance is used to accurately determine time of death. Adult Common green bottle flies on the other hand are useful pollinators, as the last photo proves. Fascinating how different stages of this fly species exists alongside both death and life.

Library Bookworm Review- Extraordinary Insects

Posted on by BITM

My latest literary listen is the audiobook ‘Extraordinary Insects’ by Anne Sverdrup-Thygeson (see Harper Collins)

I have found this book fascinating and I have learnt so much about this mostly unnoticed miniature world.

It answers the questions- What is an insect? What are the smallest and largest insects? How long have insects been around on earth? The answer to the last one is, before the dinosaurs.

Yet the author, an entomologist, also delves further and gives a wonderful insight into the varied insect lives. Her interest in and enthusiasm for insects is infectious. You will discover how insects inspire us, help with food production, clear the streets, solve crime, got Nobel prizes and more. We can even visualise a world without them.

After reading this book you will never view insects in the same way again.

Amphibians and Insects

Posted on by BITM

My week started and ended working next to ponds. The first was a small natural pond with a couple of frogs (Rana temporaria) sitting in it.

The other was a large disused outdoor swimming pool. In its neglected state rainwater collects within the concrete walls and nature is taking over. Given the murkiness of the water I was unable to obtain decent photos of my findings; however I saw another frog, (surrounded by lots and lots of tadpoles) along with a dragonfly nymph and a newt. It should be interesting to discover how many tadpoles survive to adulthood.

For the rest of the week insects were centre stage, especially on Wednesday when flying ants took to the sky. Flying ant season really tests my resolve to work through my dislike of ants (which originated in childhood). Thankfully I now find them more fascinating than loathsome, mostly.

The other insects I saw that day were;
– A (Chrysotoxum cautum) hoverfly on some Pyracantha.

– Honey bees (Apis mellifera) and a Red-tailed bumblebee (Bombus lapidarius) visiting a Geranium ‘Rozanne’ plant.

– Lavender (Lavandula) full of bees and butterflies, including more Honey bees as well as Buff-tailed bumblebees (Bombus terrestris), Meadow browns (Maniola jurtina) and a Ringlet (Aphantopus hyperantus) butterfly.

The Meadow brown butterflies also enjoyed visiting the Echinops bannaticus flowers too.

Even as I returned home I noticed a Willow Beauty (Peribatodes rhomboidaria) moth on the hall window.

The adults feed on Creeping thistle (Cirsium arvense) and Ragwort (Senecio jacobaea) both of these plants are common around this area. The caterpillars feed on various trees, shrubs as well as climbers ranging from Yew (Taxus baccata), Birch (Betula), ivy (Hedera helix), honeysuckle (Lonicera) and the wild Clematis, Traveller’s joy (Clematis vitalba).

The previous day I came across more insects that I was previously unaware of.

The first one was the Common red soldier beetle (Rhagonycha fulva).

It is a beneficial insect as adults eat aphids and are pollinators (feeding on nectar and pollen from open flat flowers such daisies and hogweed) while the larvae feed on slugs and snails along with other ground dwelling invertebrates.

The other insect I saw on Tuesday was a female Volucella pellucens hoverfly feeding on nectar and pollen from Bramble (Rubus fruticosus).

These hoverflies also pollinate umbellifers; However as larvae they inhabit Bumblebee and wasp nests eating any waste produced along with their hosts larvae.

An Enchanting Week

Posted on by BITM

My interest in plants extends to herbal medicine and floral folklore. Often found in gardens, such plants are easily accessible.

I find poisonous plants fascinating too. I would like to visit the Chelsea Physics garden as well as the Alnwick Poison Garden in Northumberland. Over the past week, a few wild flowers that I have noticed blooming would probably be found in these gardens, these are;

– White bryony (Bryonia dioica) scrambling over Dogwood (Cornus). White Bryony has poisonous berries and the plant has a very strong unpleasant purgative affect. A few deaths linked to this plant have been recorded.

– Woody Nightshade (Solanum dulcamara).

Also called Bittersweet the plant would make someone incredibly ill; the berries if eaten would cause vomiting and convulsions. There have been a few deaths linked to this plant. It is from the same family as Deadly nightshade (Atropa belladonna, See Woodland Trust).

I saw other wildflowers blooming too such as the intriguingly named Enchanter’s nightshade (Circaea lutetiana). Confusingly this flower isn’t from the nightshade family at all but is actually a Willowherb. One folkloric belief was that this plant would give protection against Elvish spells.

I also saw Field bindweed (Convolvulus arvensis) along the verges.

I continued to see many birds and insects throughout the week. After many days since the last time, I was happy to see the juvenile Blue tits (Cyanistes caeruleus) back in the Rowan tree (Sorbus). Also on Monday I had a Juvenile Robin (Erithacus rubecula) follow me around. Clearly the instincts for locating food near gardeners starts early.

The first moth I saw last week was an adult female Bee moth (Aphomia sociella). These moths are so called because they lay eggs in bee and wasp nests and also bee hives. Their larvae eat the comb, causing damage and are therefore a pest for beekeepers.

Other moths I saw were two Rosy tabby (Endotricha flammealis) moths

and a Dark arches (Apamea monoglypha) moth.

On Wednesday I was working near a fantastic old Sweet chestnut (Castanea sativa) tree. Countless Honey bees (Apis mellifera) and Marmalade hoverflies (Episyrphus balteatus) were busy flying to and fro pollinating the flowers.

As the summer continues more and more butterflies become visible. I have seen lots more Meadow brown (Maniola jurtina), Small tortoiseshell (Aglais urticae) and Large white butterflies (Pieris brassicae). One of them seen here on some lavender (Lavandula).

Also on Wednesday I observed two butterflies that I have never seen before, a Marbled white (Melanargia galathea) on Verbena bonariensis

and a Small skipper butterfly (Thymelicus sylvestris), also seen on the Verbena bonariensis.

Later on the same day I also saw ten Azure damselflies (Coenagrion puella) around the pond.

On Friday morning, as I was going to work, I had to usher a Common green lacewing (Chrysoperla carnea) outside so it could find some aphids to munch on.

Then lastly on Friday I saw a Harlequin ladybird (Harmonia axyridis) on Brunnera macrophylla ‘Jack Frost’.

Reflecting on a Blooming Lovely Week

Posted on by BITM

I am watching Wimbledon while eating lovely sweet strawberries. The window is open so I can hear the birds singing outside; thankfully the temperature has dropped and it is feeling fresher now. It is a lovely summers day to reflect upon the things I saw last week. More flowers blooming along the roadside include Hedge bindweed (Calystegia sepium) Creeping thistles (Cirsium arvense), Spear thistle (Cirsium vulgare), Field Scabious (Knautia arvensis), Ragwort (Senecio jacobaea) and Rosebay willowherb (Chamerion angustifolium). Creeping thistle seeds are a great food source for birds that make their home on farmland, while Spear thistle seeds are good for Goldfinch (Carduelis carduelis) and the nectar enjoyed by the Small copper (Lycaena phlaeas) butterfly. Ragwort (considered harmful to horses and livestock) is great for bees and the Cinnabar moth (Tyria jacobaeae) caterpillars. Even the Field Scabious is a useful food source for bees and butterflies.

Now that July has arrived, my butterfly and moth observations have increased. I have seen,

– A couple of Double-striped Pug (Gymnoscelis rufifasciata) moths

– Broad-bordered yellow Underwing (Noctua fimbriata) moth

– Least Carpet (Idaea rusticata) moth

– Plain Wave (Idaea straminata) moth

– Two Large yellow underwing (Noctua pronuba) moths

– Along with several that were photo shy including a White Plume (Pterophorus pentadactyla) moth and a couple of Large white (Pieris brassicae) butterflies, three female and one male Meadow brown (Maniola jurtina) butterflies, a Comma (Polygonia c-album) butterfly near a patch of nettles (which are great food for their caterpillars) as well as two Large tortoisehell (Nymphalis polychloros) butterflies. Other butterflies I saw were,

– A Ringlet (Aphantopus hyperantus) butterfly

– Small tortoisehell (Aglais urticae) butterfly on Verbena bonariensis

– Red admiral (Vanessa atalanta) butterfly on wall by Climbing Hydrangea (Hydrangea anomala subsp. petiolaris)

These weren’t the only insects I noticed throughout the past week as I also saw,

– Two immature male Large red damselflies (Pyrrhosoma nymphula)

– Two Azure damselflies (Coenagrion puella) on Water lily (Nymphaeaceae)

– One Harlequin ladybird (Harmonia axyridis) on a Red valerian (Centranthus ruber) leaf.

– Honey bees (Apis mellifera) on an Eryngium bourgatii

-Lots of Honey bees and hoverflies (Syrphidae) on lavender (Lavandula) which is in full bloom.

I am keeping my eye on a large mature Butterfly bush Buddleja davidii ‘Black Knight’ that is starting to flower. A few years ago I took some cuttings from this Buddleja and successfully grew one of my own. My Buddleja is only about a foot tall but it will be flowering soon. I look forward to seeing visitors arrive on both shrubs.

Lastly I couldn’t resist adding a few photos of some Cornflower (Centaurea cyanus) someone had planted in their vegetable patch. While I didn’t see any insects visiting it my attention was drawn to the cheery vivid blue flowers, they were so beautiful.
