The Heat Is On. 🔆🌡️⛈️☔

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.
