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. 🪰🧡🧡

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.

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.

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.

タイトル：Euxesta elutaとChaetopsis massyla（Diptera: Ulidiidae）の分光感受性と色の識別
実験対象：Euxesta elutaとChaetopsis massyla
要点1：両種のスペクトル感度曲線は、UV（350 nm）および緑色領域（500-550 nm）にピークを持つことが明らかにされた。
要点2：Euxesta elutaは黄色のカードにのみ引き寄せられ、一方、Chaetopsis massylaは黄色と緑色のカードに引き寄せられたが、青色のカードを避けた。

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 has keyed out to Ulidiidae, a Picture Wing Fly. There's a key, but haven't gone that far - looks like group F, foam-like patterns. Anyway, I wasn't going to do any flies today - found this in the freezer when looking for a pot of chilli for tea tonight. I'm sure it'll be a common one.

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...

![Wikipedia: Delphinia picta is a species of picture-winged fly in the family Ulidiidae. The specific name picta is from Latin and means "painted."[6] It is the only species in the monospecific genus Delphinia. It is found in the United States on the East Coast and in the Midwest from Florida to Maine across to Kansas through Minnesota[5][1][4] but also can be found in Mexico[7] and El Salvador.[8] It is sometimes mistaken for a species of fruit fly, but D. picta do not feed on living plant matter, as they are detritivores and eat decaying plant matter.[5][4][9] They also have been observed eating fermenting frass from Megacyllene robiniae on black locust trees.[10] They can be found almost anywhere there is decaying vegetation: landfills, temperate deciduous forests, swamps, and even shaded fields.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:bmoinxm3zcmayhujha3ulwlu/bafkreihegrt4qeeyse2xs4wvw5xgfrcchn2drltk2xc6fhyahl6y56a5ze)
