@markmccaughrean Fortunate, #Conopidae are spectacular flies. This season I've only stumbled upon one single specimen , so far.
@emmecola @TarkabarkaHolgy The plot thickens: flies caught in a ménage a trois.

So what's an internal parasite maggot got to do, to successfully keep the host (a bee or wasp) alive until it's ready to pupate?
For one, hold all its poop in its gut. Otherwise it would intoxicate and kill its host.
So what's the first thing that the adult conopid fly must do upon hatching? My guess is: take a huge dump!

Of my 12 observations this year of conopid* flies – mostly parasites of adult wasps – from US, UK and Croatia, none have collected a single comment or endorsement of the genus or species.
Did I get them right? Hopefully. Am I an expert? No. Just wish there was a guide out there on these fascinating flies. How they ever evolved into being is a fascinating thought to entertain.
* Conopids are also known as thick-headed flies, beegrabbers and waspgrabbers. For their life history, see: Gibson's thesis (2011), titled "The evolutionary biology of Conopidae (Diptera): a life history, molecular, morphological, systematic, and taxonomic approach" https://repository.library.carleton.ca/downloads/ks65hc719 which, among other details, has "the first ever key to world genera of Conopidae".
Conopid mating habits remind me of frogs.
First unusual fly of the season:
Myopa vicaria, a conopid https://www.inaturalist.org/observations/204696300
The larvae of these flies are all internal parasites, "most of aculeate (stinging) Hymenoptera. Adult females aggressively intercept their hosts in flight to deposit eggs." https://en.wikipedia.org/wiki/Conopidae
There are still very few insects around, but I found this Myopa fly staring at me.
