Here's another picture of it; and also a short series of another novelty for me which Penny spotted on a windowsill yesterday and neither of us recognised in spite of its distinctive and somewhat menacing appearance.
Menacing is an appropriate word because this is a a Bee Fly, rejoicing in the fine Linnaean name of Bombylius major, which uses its mimicry to act as a parasite on the larvae of genuine bees. Poor embattled creatures, as if the current concern about disease and pesticides wasn't enough. The Natural History Museum's excellent website says dramatically: "The female has been seen to flick her eggs mid-air into ground bees’ and wasps’ nests."
Finally, on a lovely sunny day, we saw a couple of fine Brimstone butterflies on a classic English countryside walk which took in the deserted village and numinous, ruined manor house of Hampton Gay. The Brimstone's colouring as a 'butter-coloured fly' is one of the most commonly-cited reasons for the curious word 'butterfly', although without conclusive evidence.
I didn't get a picture of them, nor of the many Peacocks and a few Small Tortoiseshells which were enjoying the sunshine. But I managed to snap this lovely female Holly Blue, whose white wing-trim suggests very recent hatching. Sorry she's a bit blurred and a bit coy about opening her wings to their full, lovely extent.
