Just found one of these sheltering on our porch during a brief rain downpour just now. Always nice to find an easily identifiable fly, the spines on the wing edge were most helpful! #heleomyzidae

Crack open the champagne...I just passed 1000 identifications of Suillia variegata on @inaturalist.bsky.social ! Easily the most commonly recorded spiny-winged fly across Europe....and easily the easiest member of the family to identify from a photo! 🙂 #heleomyzidae @dipteristsforum.bsky.social

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

My 1st ever record of an undescribed species of #Tephrochlamys. ID confirmed. Unlike other members of the genus, this species has a pair of presutural dorsocentral bristles. #Diptera #Heleomyzidae #CemeteryWildlifeWatch recording activity on #iRecord.

Gymnomus caesius (Heleomyzidae)...stunning orange and grey, spiny-winged fly of woodland, with males often holding territory on logs. All records gratefully received on iRecord. 🙂 Allerthorpe Common, East Yorkshire today. @dipteristsforum.bsky.social #heleomyzidae dipterists.org.uk/heleomyzid-s...

Finally some fungi appearing locally in East Yorkshire, and with those come the fungus-breeding, spiny-winged heleomyzid flies, like this gorgeous Suillia notata at Cali Heath @yorkswildlife.bsky.social reserve. #heleomyzidae @ynuorg.bsky.social @dipteristsforum.bsky.social

Always nice to record Suillia variegata at #RSPBMiddletonLakes, 23/04/25 @suillia.bsky.social @dipteristsforum.bsky.social #fly #Diptera #Heleomyzidae

A really nice #Heleomyzidae fly, I just don't know which one @suillia.bsky.social! Seen at #RSPBMiddletonLakes 20/04/25 @dipteristsforum.bsky.social @rspb.bsky.social #Diptera #fly

A #Heleomyzidae fly? Seen in my Staffs garden 22/02/25 @dipteristsforum.bsky.social @suillia.bsky.social #Diptera #fly

Scoliocentra villosa ♂ (Heleomyzidae). One of my favourite flies...large, orange and blue-grey, with a soft fuzziness throughout. And they live in caves and badger setts and hang around mammalian corpses...what's not to like?!! #heleomyzidae #ento @dipteristsforum.bsky.social

Scoliocentra flavotestacea female #Heleomyzidae from Creag an Lochain, Ben Lawers last summer. An uncommon species according to @suillia.bsky.social great ID resources available here: dipterists.org.uk/heleomyzid-s...

The spiny-winged fly Neoleria propinqua on a fern frond beside a dead rabbit. Larvae develop beneath the corpse.

Neoleria propinqua (Heleomyzidae) ♂ in woodland at Cali Heath, Yorkshire today. A common species around carrion in the early part of the year. #heleomyzidae #diptera #ento

Suillia fuscicornis #heleomyzidae on a relatively warm morning at Allerthorpe Common in East Yorkshire, UK. As usual, a male holding territory atop a small fungus. #diptera #ento #ukwildlife @dipteristsforum.bsky.social

Tephrochlamys tarsalis, a common spiny-winged heleomyzid fly whose larvae develop in birds' nests, small mammal burrows...etc

Tephrochlamys flavipes, a common spiny-winged heleomyzid fly whose larvae develop within birds' nests, smal mammal burrows..etc.

Tephrochlamys rufiventris, a common spiny-winged heleomyzid fly, often found around the bedding of domestic rabbits, guinea pigs...etc

The three common UK Tephrochlamys species....first time I've had all three together in the garden shed where our guinea pigs spend the winter! #heleomyzidae #diptera #ento dipterists.org.uk/heleomyzid-s...

A pair of grey and orange spiny-winged flies Neoleria propinqua mating, with the male on top looking as though it is leap-frogging over the female!

Not entirely sure whether this is copulation or a game of leap-frog! Several pairs of Neoleria propinqua (Heleomyzidae) in cop. today, not remotely affected by recent snow and yesterday's -6 degrees. #ento #diptera #heleomyzidae

A pair of spiny-winged flies Neoleria propinqua (orange abdomen/grey thorax/reddish eyes) mating on a fallen Alder leaf.

Below freezing overnight, but winter-active spiny-winged flies don't care! Neoleria propinqua in cop. alongside a dead Rook. Categorised as provisionally Near Threatened in the last review, but actually far from uncommon around carrion in winter. #ento #heleomyzidae @dipteristsforum.bsky.social

An orange heleomyzid fly, Suillia notata, sitting atop a mushroom, facing right.

I can only apologise for the fact that there will be lots of photos of spiny-winged flies here...today's a Suillia notata ♂ as usual holding territory atop a mushroom. No serious frosts yet, so the woods are still alive with Suillia. #ento #UKwildlife #britishwildlife #heleomyzidae

#Heleomyzidae Heleomyza borealis, female, Ben Lawers, http://26.vi.21 A remarkably cold tolerant species that is widespread in the north of the UK. Length c. 6mm. #Diptera
