#flybuary day 4! promachus yesonicus is called ใ‚ทใ‚ชใƒคใ‚ขใƒ– (shioyaabu, salt peddler "horsefly") in japanese because of the male's white tail. promachus are huge robber flies and are one of the few genera of asilids that lay frothy white egg masses. buy his salt or else.

Ok so Iโ€™ve seen a lot of pinned insects in my time but Iโ€™ve NEVER seen wing rests for mosquitoes

The @unirdgento.bsky.social have been charged to give me data about these specimens in the @uniofreading.bsky.social collection because they are FABULOUS

Call out to anyone with UK records of Sphaeroceridae not on NBN/iRecord. Looking at getting the best distribution possible for a new key, I realise this will be a 'best possible', but more the merrier. Please share @dipteristsforum.bsky.social @flygirlnhm.bsky.social @respublications.bsky.social

Ahh the problem with common names

The original description of this image -'Fruit flies undergo a prelude of dances prior to mating'

It's a Tephritidae - a fruit fly. NOT Drosophila - what many refer to as a fruit fly (from family Drosophilidae aka Vinegar flies). Quite different (see image of cat)

Don't let this delicate little muppet fly fool you - larvae are voracious predators of armored scale insects! A member of the "gall" midge family, it has abandoned plant feeding for a meat-based diet (like many others).

Host = white prunicola scale; #Diaspididae

My first louse (flat) flies of the year! Stenepteryx (Crataerina) hirundinis puparia (Diptera: Hippoboscidae) with flies emerging about 5 months early. I probably should have kept them somewhere cooler!

my modest collection of flies with WIDE heads ๐Ÿ™‡

a hammer-headed Richardia (Ecuador),
a stalk-eyed Chaetodiopsis (Mozambique),
a pointy-eyed Ophthalmoptera (Colombia),
and an antlered Richardia (Colombia)

why though? male-male competition? sexual selection? chime-in if you know!

Nearly there, eyes on the prize of Christmas Day. Talking of eyes, some of the best eyed creatures are stalk-eyed flies including Plagoiocephalus latifrons (image @bertonemyia.bsky.social) we saw in Costa Rica

Cover photo - Male Diostracus prasinus Loew (Dolichopodidae) from Kephart Prong Trail in the Great Smoky Mountains National Park, North Carolina, USA. This species has fascinatingly pubescent palpi which shimmer in the light and are used for courting interactions. Photograph by Zachary Dankowicz. Cover of the issues shows a long-legged fly standing on a natural surface staring at the camera. It has green eyes with diffuse reddish stripes and a metallic green thorax. It has a pair of bright white, flat palps around the mouth.
