as a pretty ignorant dipterist, I only just now found out that all the craziest flies I saw in Colombia last August were all Tephritoids - cool!

1 pointy-eyed Pterocallini - Ulidiidae
2 psychedelic-eyed Paragorgopis - Ulidiidae
3 blue-winged Setellia -Richardiidae
4 antlered Richardia infestans

Voor #ElkeDagEenInsect een voor mij onbekend vliegje van #Saba, dat de fraaie vleugels heel sierlijk op en neer bewoog tijdens het drinken. Ulidiidae of Tephritidae misschien? Is er een dipteroloog in de zaal?

This wee fly would appear to be a new species for Britain. I think it's Tetanops sintenisi (family Ulidiidae). Seems to be an east European thing that's spread west and is now widespread in Netherlands. I've got four from a vane trap near Ipswich from May/Jun this year.

Stalked eyes or at least modifications similar to that are found in several families. Very common in Tephritoidea like the ones above & this picture-winged fly (Ulidiidae). More of a broad head in some (like Periscelididae below) & pointy eyes in others: www.inaturalist.org/observations...

A macro photo of a deep magenta peony bud covered in glistening raindrops, with a small fly perched on a nearby leaf. A fly, likely from the family Ulidiidae, such as a Chaetopsis species

My new friend, Delphinia picta, a species of picture-winged fly in the family Ulidiidae. The specific name picta is from Latin and means "painted". It is the only species in the monospecific genus Delphinia.

The photo isn’t the clearest but I love their little shadow. 🪰🧡🧡

I'm always captivated by the delightfully named Peacock Fly, Callopistromyia annulipes (Macquart, 1855) [family Ulidiidae]—this one was strutting on a log while waving its wings #FlyFriday #Diptera

A walk in Panshanger Park yesterday produced some not uncommon but attractive insects (I was looking for some leps). #insects #panshangerpark.
Anaglyptus mysticus. Rufous-shouldered Longhorn Beetle. No matter how many I see its beauty always amazes me. Piezodorus lituratus. Gorse Shielbug. Love the yellow legs with reddish socks. Miris striatus. Wonderful colours. Dorycera graminum. Phoenix Fly. Which I initially mistook for a Sciomyzid till put right 😟. It’s a Ulidiidae fly.

This is a male stalk-eyed #fly from Costa Rica. Females lack the hammerhead while males "compare sizes" for a chance to mate. Evolution is magical 🪄

A fly on a white background with extremely wide and narrow eye stalks, making the head as wide as the wingspan and longer than the body. It has wings with a thick, dark wavy line, and they are held out to the side of the body. A fly on a white background with extremely wide and narrow eye stalks, looking at the camera. It looks like a pencil sitting across the face of a fly with an eye at each end.

At least some are patterned to mimic jumping spiders, viewed from behind - common in many Tephritoidea (see Ulidiidae below). Many also use their wings to signal to mates, so they may function to distinguish species. Otherwise?????
a picture winged fly specimen that has shiny fake eyes on the back of its thorax and markings on its wings that look like spider legs. it's a convincing mimic a picture winged fly specimen that has shiny fake eyes on the back of its thorax and markings on its wings that look like spider legs. it's a convincing mimic

A nice little fly from Chicksands Wood, pretty sure that this is Otites guttatus, a fairly localised species that I've only come across once before. #Fly #Insect #Nature

Too many negative perceptions of true #flies, #Diptera, but they're SUPER diverse! Take a moment to appreciate a few of the many wonderful forms:

bee #fly; #Bombyliidae: #Ogcodocera
peacock fly; #Ulidiidae: #Callopistromyia
flat-footed fly; #Platypezidae: #Bertamyia
crane fly; #Tipulidae: #Orimarga
A plump, fuzzy bee fly sits on a dead pine needle on the ground. It has a white face and rump, and maroon eyes, but the rest of the body is black, with half black wings. A gray and black peacock fly. It's holding its wings upright, with their undersides showing forward. The wings are spotted, and the fly looks like a peacock. A small, elongate fly with small mirror patches on it. It has huge red eyes making up most of the head. It's resting on a leaf. An extraordinarily thin black crane fly. The thin wings are also wrapped around the body, giving it a stick-like appearance. It has pale legs with dark knees.

One of my summertime favorites: the ant-mimicking #fly #Myiomyrmica fenestrata (Order #Diptera, Family #Ulidiidae). I've found this species at only one location: Loda Cemetery Prairie, Loda Illinois. They look & act like #ants. I haven't a clue about their role in #tallgrass #prairie ecosystems
Mating pair of Myiomyrmica fenestrata flies resting on a diagonal stem. Both sexes are brownish-red in color with typically "gas-mask" looking faces and narrow wings with a single white-ish patch near the wing tip.

That's the thing about insects; you never know what you are going to come across. Take this tiny fly Physiphora alceae; a member of the picture-wing group Ulidiidae that doesn't have pictured wings! Our garden turns out to be only the 2nd Staffordshire location and it the 3rd county record.

Ulidiidae (picture winged fly) maybe? I've still got the Manual of Nearctic Diptera from my lab days but I'd need a microscope and a specimen to key it out. bugguide.net/node/view/22...

Het is een prachtvlieg (Ulidiidae) van Noordwest-Europa, dus klimaatverandering denk ik niet. Gewoon een zeldzame soort. Maar had je die kortgeleden? Vliegt meer in april en mei.
