Scoliocentra villosa ♂ on a fallow deer corpse at #AllerthorpeCommon this week. A favourite spiny-winged fly, found around badger setts, carrion and in caves. This one rather lacking in the fore tarsal area! #Heleomyzidae @dipteristsforum.bsky.social @ynuorg.bsky.social

An excellent morning with the Devon Fly Group at their indoor meeting. Topics ranging from potential flies of Atlantic Rain Forest in UK to key entomologists in the history of Dolichopodidae. Great group who get so much done! #localgroups @guyshrubsole.bsky.social @teamdiptera.bsky.social

A fantastic piece of work, a superb guide to the marvellous diversity of diptera in these islands.
And I'm very happy to have contributed a couple of photos: see my Colobaea bifasciella on p. 251.

Heleomyza serrata

Tephrochlamys rufiventris

Gymnomus caesius

Nice morning at Bempton Cliffs...birds were good, spiny-winged flies were better! 😀 Hundreds of Heleomyza serrata, Tephrochlamys rufiventris, Gymnomus caesius and more on handrails by the cliff edge. Always worth having a few pots in the pocket. 😉 @dipteristsforum.bsky.social @ynuorg.bsky.social

Great images Ian!

What better for #FlyFriday than a phantastic phebruary phorid lurking outside a rabbit burrow at @yorkswildlife.bsky.social Cali Heath reserve in East Yorkshire, UK today?! @dipteristsforum.bsky.social

Love a good phorid!

Calliphora vomitoria (Calliphoridae) female. greyish jowls/cheeks and orange beard. 20/2/2026 Topsham, Devon.

Bluebottles from Topsham Cemetery posing helpfully to show differences:
Yellow jowls + dark beard = Calliphora vicina.
Grey jowls + orange beard = Calliphora vomitoria.
