Longrock SSSI Whitstable Kent 9/11. Saw this striking fly which looks good for Ectophasia crassipennis a recent addition to the British list but have been seen in more frequently in the county @kentfieldclub.bsky.social #flies #insects #tachinid #inverterbrates #ukwildlife

Not a hoverfly but a Tachinid, parasitic on shieldbugs.

The Tachinid Ectophasia crassipennis was a surprise visitor to the last remaining Ox-eye Daisy in the garden today. Apparently new to Britain in 2019, and now widespread in Kent according to the NBN atlas. #flies #diptera #KentNature
A fly on an Ox-eye Daisy flower head. It has a black abdomen with orange patches, and broad wings with a dark central patch.

Some goth flies from last weekend to wrap up #flyday. Tachinid fly Juriniopsis adjusta and the appealingly named Wavy Mucksucker (Orthonevra nitida).
#natureismetal #insects #macrophotography #flyfriday
Fly on small yellow and white flower. Fly has white face, dark red eyes, and spiky hairs on its body and legs. Fly whose eyes have darker curvy designs on them and a bronze thorax. (Unfortunately not all in focus).

It's almost the weekend! 🥳

If you're looking for something for you and/or your kids to do, I've recently re-uploaded my arthropod coloring guide 🎨

Please feel free to share, print, and [definitely] have fun with it!!!

A few panels from the coloring guide: a scorpion, an isopod, and a tachinid fly (along with their info).

Apologies for forgetting this month's #InvertArtChallenge again and thanks once more to @petrathepostdoc.bsky.social for the reminder.

This month we travel to Scotland for this wonderful tachinid fly. I don't know the species, so if anyone does, please lmk.

Feel free to create using this photo!
a curious fly on white composite flower. the fly is fuzzy black with a spikey butt and a bare, cream colored head and orangish tinged clear wings

I wasn't that excited about this stock standard photo of a darkling beetle (Eleodes goryi), until I noticed the parasitic tachinid fly egg attached above the insect's midleg. This beetle is on borrowed time.
Side view macro photograph of a large black beetle with densely dimpled elytra, standing amid yellow fall leaf litter. An oval orange shape is visible on the side of the beetle.

Morning! This is a tachinid fly known as the Maruboshi Hirata Yadoribae.

Possibly the tachinid fly ectophasia crassipennis, feeding off yarrow, seen yesterday on Stockbridge Down (Hants), for #WildWebsWednesday

Eriothrix rufomaculata on thistle.
A delicate body, an uncompromising life cycle.
A beneficial predator in the meadow’s quiet system of checks and balances.
Close-up of Eriothrix rufomaculata, a small dark fly with reddish markings, perched on the spiny flower head of a thistle. The fly’s fine body hairs catch the light, while the thistle spines radiate outward sharply. The background is softly blurred green, giving a calm yet focused atmosphere. Tachinid flies like this one are parasitoids: their larvae develop inside caterpillars, which helps regulate herbivore populations and maintain ecological balance in meadows.

Come fly with me, let’s fly away. Caught this glossy little aviator mid-sunbathe. A tachinid fly, google search so could be wrong, nature’s pest control (apparently!), styled in jet-black. ✈️  #insect #MacroMonday #MacroPhotography #IrishWildlife  #NatureStory #CloseUp #WildIreland

This parasitic fly was probably one of the most interesting things I photographed on our hike this morning.

It is a type of Tachinid fly, likely Adejeania

This Monarch caterpillar had been parisitized by Tachinid fly. It's not always this obvious. There definitely were some hard days on our #MonarchRanch. #PlantMilkweed

Wow!! So many!
Early in season I was doing pretty good w/my releases, then as summer wore on, the darn Tachinid fly would get them! Even from eggs!

The tachinid fly Ectophasia crassipennis in Calverley Grounds today. Quite new as part of the UK fauna and now widespread around Tunbridge Wells

A Juniper Shieldbug (Cyphostethus tristriatus) and a Parent Bug (Elasmucha grisea) seen together on a leaf of the garden birch tree this afternoon. The Parent Bug has two Tachinid eggs on its scutellum which is bad news for the Parent Bug.

#UKWildlife #Shieldbug #Hemiptera
A pale green birch leaf with two shieldbugs on it. The bug upper left is bright green and has two boomerang shaped chestnut brown stripes on its back. The bug lower right is predominantly chestnut brown and has two small white spots on its back that are fly eggs.

Swift feather-legged fly (Trichopoda pennipes), a tachinid parasitoid of squash bugs that has a row of blade-like setae on the rear tibiae. Native to North and South America but apparently now also in Europe and elsewhere. 🌿 #diptera #flies #insects
Fly with orange abdomen and outstretched, dark wings foraging on an inflorescence of tiny yellow flowers. Rear view of the fly to show the long, feather-like extensions on the hind legs.

Happy to see this large data release and analysis of decades of #tachinidae collected by #DanJanzen, #WinnieHallwachs and the #parataxonomists of #ACG @gdfcf.bsky.social in #CostaRica. So much diversity!

Figure 1. Four representative tachinid species from ACG. (A) Patelloa ‘xanthuraDHJ01’ voucher DHJPAR0034758; (B) Chorotegamyia sp.; (C) Spathidexia atripalpus; (D) Phosocephala alexanderi female voucher DHJPAR0048468. Photo credits - AJ Fleming CNC bipartite diagram showing the host-specificity of ACG tachinids in the genus Belvosia. Species in red were formerly known as one species that is now known to be three by host-use and genetics. Where formalised names exist, they are largely honoring ACG paraxonomists. Venn diagram of the overlap between the diversity of ACG tachinids known from rearing larval lepidoptera versus those that are collected in Malaise traps. Only 18.5% overlap. Evident decline in the abundance of tachinid parasaitoids (here counts/year for the two most abundant subfamilies) in ACG after the stabalisation of the parataxonomist collection workforce in ~2005

I thought at first this was Phasia hemiptera but i now think it is a male Ectophasia crassipennis (seen in Sussex)? A recent colonist to BI in 2019 that is established in the south and now spreading north. No NBN records for Derbys/Notts.
A small fly that resembles a new tachinid fly species that arrived in Britain in 2019.
