Just had this sent in as a record of Little Snipefly (Chrysopilus asiliformis) - which is absolutely correct if you look closely and ignore the Marbled White! (📷 by Ian Joseph)

@uk-soldierflies.bsky.social potentially 2-3 Villa hottentottas found this afternoon also at Swanscombe? I've uploaded to irecord
@uk-soldierflies.bsky.social Is this Villa hottentotta? Found this morning at Swanscombe marshes. Could only manage this one photo before it flew off, and being quite windy I couldn't find it again
Rare glimpse of Twin-spot Centurion Sargus bipunctatus NT Erddig Park. Our largest Sargus species 10mm, named after two White spots near antennae. Vastly under-recorded September species on another Riverside Rarity Horsemint Mentha longifolia @uk-soldierflies.bsky.social @bsbibotany.bsky.social
Usually appearing around this time of year in the garden - Twin-spot Centurion (Sargus bipunctatus) Soldierfly. Photo'd on 8.9.26 @uk-soldierflies.bsky.social
A real beast of a fly and one that until today had somehow eluded me in the UK. Thanks to @johnwalterswildife.bsky.social for the location info. Hornet Robberfly (Asilus crabroniformis) @uk-soldierflies.bsky.social #Diptera
Agreed - yellow on all abdominal segments + pale stigma mark on wing = C. nagatomii (rather than the darker C. tibialis)
@uk-soldierflies.bsky.social Went out in search of a female C. nagatomii Bright Four-spined Legionnaire after finding a few males last week. Along with a couple of males, I believe I did find a female. Can you please confirm from these photos I did find a female? Before I put on iRecord.
Great work by @speciesrecovery.bsky.social to monitor and conserve the Barred Green Colonel #soldierfly (Odontomyia hydroleon), one of the rarest #flies in the UK - thanks to @suillia.bsky.social and @judywebb.bsky.social for their expert advice
Scientists study this rare fly using ... grapefruits A thread for #SpeciesOfTheWeek ⤵️
Mating pair of the UKs largest true fly the Hornet Robberfly Asilus crabroniformis. The male often covers the female's eyes during mating presume to prevent her from flying off after potential prey. Dartmoor, Devon today.
There have been convincing records in 2026 of Buff-tailed Villa (V. hottentotta) in Kent and Essex. Please check carefully if you find something that looks like Dune Villa (V. modesta) but in locations away from the dune habitats.
... 2/2 Finding Buff-tailed Villa (Villa hottentotta) in UK meant the Villa ID guide needed updating! See dipterists.org.uk/soldierflies.... Convincing photos of the new Villa were taken in 2025, but we need a specimen to fully confirm it. If anyone finds more next summer please let me know!
Hornet Robberfly Purbeck Heaths NNR, Wareham, Dorset @uk-soldierflies.bsky.social @dorsetwildlife.bsky.social
This Hornet Robberfly our largest I believe, just fell at my feet at Badbury Rings ,just asking to be noticed .😅 plus another earlier one trying to hide . @dorsetwildlife.bsky.social @britishnatureguide.bsky.social @uk-soldierflies.bsky.social
Citizen science data reveals changing seasons for Britain’s Dark-edged Bee-fly Emergence has shifted around 9 days earlier since 1984, with the flight period shortening by ~13 days. @uk-soldierflies.bsky.social resjournals.onlinelibrary.wiley.com/doi/10.1111/...

And now back to the Insects! Rhagio tringarius, Marsh Snipefly, seen 23/07/26, Isle of Bute @uk-soldierflies.bsky.social @dipteristsforum.bsky.social #Snipefly #Diptera
The gorgeous little Rhagio lineola Snipefly, seen in the woods on the Isle of Bute, 30/07/26 @uk-soldierflies.bsky.social @dipteristsforum.bsky.social #Diptera
The recording scheme has received more records of Hornet Robberfly in 2026 than in any previous year, and they are still coming in! More records doesn't prove that there are more flies, it might also be more recorders, but I'm taking it as a very positive sign for this species
The lovely @wildkatdahl.bsky.social & I went looking for Asilus crabroniformis (hornet robberfly) & weren’t disappointed - 20 including 4 mating pairs!! (Last image Kats 😎). A fab Sussex bottom Perfect habitat - chalk with dung @dipteristsforum.bsky.social @uk-soldierflies.bsky.social
Tabanus autumnalis ♀ today in Bengeo garden, massive horsefly associated with marshland & Herts rarity. Easily largest fly I have seen in garden. 6th tabanid species recorded here. @uk-soldierflies.bsky.social #Tabanidae
Just look at the eyes on this (deceased) Twin-lobed Deerfly! Chrysops relictus 💚 #UKwildlife #Sussexwildlife #insects @dipteristsforum.bsky.social @sussexwildlife.bsky.social
Brilliant photos of a very rare fly, the first record of this species that we've received for many years, so it is very welcome that this population is still present.
Delighted to find Thereva valida (Dark Northern Stiletto) at Ashberry yesterday. A rare stiletto fly, but with known population on south side of North York Moors. Thanks to @kitenet.bsky.social for confirming from photos. @uk-soldierflies.bsky.social @dipteristsforum.bsky.social @ynuorg.bsky.social
Great to see this paper published, based on #BeeFlyWatch data - thank you to everyone who has ever sent in a bee-fly record 🙏 @dipteristsforum.bsky.social
New work in #RESInsectConsDiv #CitizenScience data reveals that earlier & shorter flight periods correlate with climate warming in the dark-edged #BeeFly doi.org/10.1111/icad.70114 #Phenology @manusaunders.bsky.social @wileyecology.bsky.social @unirdgento.bsky.social @uk-soldierflies.bsky.social
Kite-tailed Robberfly (Machimus atricapillus) from the conservatory this morning. @uk-soldierflies.bsky.social
"Site of Special Soldierfly Interest" gets a big thumbs up from me!
I think that I am going to declare my pond SSSI - site of special Soldierfly interest Third large Stratiomyid species this summer Beautiful Stratiomys pontamida #soldierfly @dipteristsforum.bsky.social @norfolknats.bsky.social @amentsoc.bsky.social
For a moment I thought I had seen a red-eyed horsefly - until I blew up the image. It has a passenger!
This does indeed appear to be the first report of Villa hottentotta (a female) in 2026 🎉👏, not too far away from one of the sites where it was first discovered in 2025. Thanks for adding the record to iRecord - it will be fascinating to see if more are found.
@uk-soldierflies.bsky.social Is this Villa hottentotta? Found this morning at Swanscombe marshes. Could only manage this one photo before it flew off, and being quite windy I couldn't find it again
A late summer feel to Dartmoor yesterday with my first Hornet Robberfly Asilus crabroniformis of the year. This 'google eyed' monster is a predator of small insects such as flies and dung beetles which it catches in flight with its spiky legs. Venford Resevoir, Devon
I caught up with a few old friends on one of my local heaths on Purbeck this afternoon: the hulking Hornet Robberfly, the exquisite Mottled Bee-fly, & the absolute unit that is the Heath Tiger Beetle.
Looking forward to seeing lots of lovely soldierfly records 🤗
The Dipterist Forum Summer Field Meeting starts today in Somerset! By exploring a wide range of habitats across 56 sites over a week, thousands of new Diptera records will give a clearer picture of the abundance, distribution and ecology of this much over looked Order of insects. #fliesarefantastic
@flygirlnhm.bsky.social Two new soldier flies for me today, on the same hydrangea in my stepmum’s garden. Both recorded. Thanks to you, although I didn’t recognise them. I knew they were soldier flies immediately on seeing those abdomen.
A Large Marsh Horsefly (Tabanus autumnalis) just rescued from our conservatory this evening. The second I’ve seen there in a week. Very large and a fearsome proboscis! @uk-soldierflies.bsky.social @kitenet.bsky.social
Oxycera nigricornis ♂ today in Bengeo garden, attractive tiny aquatic soldierfly. @uk-soldierflies.bsky.social #Stratiomyidae #attractedtolight
