Black Scavenger Fly (Sepsidae)
A bit late for #FlyDay. Anyway, please enjoy this lovely syrphid fly, a striking dark brown/black with bright yellow stripes nectaring on a bright purple/blue aster with a yellow center.
I went for a run yesterday. Saw a red fly. Photographed it. Shared it on #iNaturalistNZ. (As I do.)
Turns out it's the first observation of the species from Ōtautahi-Christchurch city on #iNaturalist, and the fourth from Canterbury.
All Canterbury observations of this species on #GBIF, the Global Biodiversity Information Facility, are from iNaturalist.
Discovery is easy!
We’ve just named a new species of fly from Yemen! And it came out of a flower from #Kew - read more about it here:
Goldenrod Gall Fly (Eurosta solidaginis) Gall
A Beetle Fly, genus Celyphus, spotted at MacRitchie Reservoir Park, Singapore, on 18 May 2023. A fly that looks like a beetle with that shield over its wings, it is tiny, but recognizable by its strange looks.

Monthly totals of specimens of the Tachinid fly Eumea linearicornis that I have collected in the area of Reading, UK since April 2014. This is another case of a female-only autumn generation (which might or might not be a disruptive consequence of the warming climate).
Something a little different for #FlyDay! These fantastical polka dots are induced by the dogwood eyespot gall midge, _Parallelodiplosis subtruncata_. Yes, these too are flies. They don't really harm the tree.

Eastern Calligrapher (Toxomerus geminatus) on an American Aster (Symphyotrichum sp.)
Found a stump this week with several Zelia lurking about. In at least one species in the genus, females give birth to motile larvae, depositing them at the holes in decomposing wood made by beetles. The larvae then crawl along the tunnels until they find hosts to burrow into. #fly #diptera #zelia #tachinidae #insect #nature #entomology #FlyDay
Inaturalist tells me that both of these are quadrate snipe flies (Chrysopilus quadratus), but their coloration is very different. Does anyone know why? They both look like males, with their head-encompassing (holoptic) eyes. Is there just this much color variation, or have I mis-identified them?
Despite appearances, this photo wasn’t taken in a studio, but on a late afternoon walk with the sun low on the horizon and no flash at all: the sun was my flash, shining on from under my camera.
Siphona sp. (tentative ID) http://www.inaturalist.org/observations/181805824
Nematoceran fly —aka mosquito or midge-like— sipping nectar, its head and paintbrush antennae (the size alone labels it as male: their purpose is to locate females) bobbing up and down as if listening to heavy metal. Wish I recorded a video.
Faintest idea what species this is, I have not.
How cool. I never managed to identify these maggots from a microbial mat in Yellowstone National Park. By comparing with the larvae of alkaline flies in the video, I see they also have spiky prolegs–perhaps members of the same family, since most dipterans don't have them at all.
Digging a bit, I have this other adjacent observation of adult flies walking on those waters https://www.inaturalist.org/observations/28847765 labeled as Ephydridae ... they are likely related if not the same species.
According to https://www.inaturalist.org/taxa/343983-Volucella-zonaria there are many observations in the UK indeed, but I've only ever seen Volucella zonaria once in the UK.
The large hoverfly I see frequently, at least in Cambridge, is the yellow-haired sun fly, Myathropa florea https://www.inaturalist.org/observations/180250789 This one seems like a mimic as well, but its larvae grow on detritus in moisty ground.
Hornet mimic hoverfly, Volucella zonaria http://www.inaturalist.org/observations/179384134 which not only resembles (somewhat) a hornet, but also lays its eggs in a hornet nest and its larvae grow up as commensals therein https://en.wikipedia.org/wiki/Volucella_zonaria#Biology Badass!
Mystery midget: #iNaturalist auto-suggestion didn’t even guess the insect order correctly. Holds itself like a mosquito, but only measures about 2.5 mm. Found on a pebble beach by a white pine tree secondary forest.
We've made it to #FlyDay! I think this might be Neurigona deformis (Dolichopodidae). When the flash went off it would dart away, then return in a fraction of a second to almost exactly the same spot (something long-legged flies tend to do). On a rotting log in Media, PA, USA. #fly #diptera #insect #entomology #moss #nature
I am sad and angry over trees next door being cut down so I had a croissant and took a LOT of bug pics and now I'm going to take a sad nap :blobsad:
- baby zebra jumping spider (_Salticus scenicus_)
- long-legged fly (_Condylostylus_?, family Dolichopodidae) on hostas
- bumblebee (_Bombus_?) on coneflower
- pseudoscorpion (Cthoniidae? Neobisiidae?) :pseudoscorpion:
It's not the best photograph but I think that blur above the ant's pronotum is Apocephalus coquilletti, a scuttle fly that injects eggs into Camponotus workers. After completing their development the fly apparently causes the ant's head to pop off, using it, I guess, as some sort of escape pod. The fly was amazingly good at tracking every evasive maneuver the ant attempted, making it seem like they were joined by a metal rod. Found it yesterday and now I'm obsessed with finding more. #phoridae #diptera #fly #insects #entomology #ants #nature
Plant makes fake bee blood to lure in jackal flies.
Yay! The CSIRO's "Anatomical Atlas of Flies" is available once again. This is an online interactive atlas of fly anatomy. It was originally implemented in Flash, and died when Flash died, but it's been resurrected now as JS and HTML.
This is a great resource for anybody who loves flies (and isn't that everybody?)
got sunburnt sat by the pond watching the bugs but it was worth it ☀️ (don't be like me and always wear suncream folks)
• marmalade hover fly (Episyrphus balteatus)
• blue emperor (Anax imperator)
• black tailed skimmer (Orthetrum cancellatum)
• tapered drone fly (Eristalis pertinax)
bonus: lots of blue damselflies (Enallagma cyathigerum)
Somebody in Cleveland, Mississippi, sent me some photographs of mosquitoes massed near her front door. Images aren't that clear but I'm wondering whether anyone can help me ID them. They look like Anopheles quadrimaculatus, and that might make sense given rice farming in area. #mosquito #mosquitoes #diptera #Mississippi
A Violet Leafwalker (Chalcosyrphus chalybeus). These flies are wasp mimics. They even flick their wings the way mud-dauber wasps do. From some angles they are dark, Darth Vader black. From other angles they have the color of cobalt blue bottles.
A yellow dung fly (#Scathophaga stercoraria) looking for prey.
Although its Latin name suggests that it feeds on dung, it is actually a hunter of smaller insects.
