Sadly, I missed #worldrobberflyday - but here’s some Leptarthrus brevirostris from Lochawe (VC98) last week. Excellent numbers, so a big local emergence, of a species that is near annual at the site @dipteristsforum.bsky.social @uk-soldierflies.bsky.social

My first tweet 10 years ago was a robber fly photo on #worldrobberflyday. Saw this robber fly today, thought it'll be a good post to start with on my new BlueSky account. Eye-to-eye, a Fly is eating a Fly....

For #WorldRobberFlyDay I'd like to show off some of the cool robber fly merch I've gotten from some super talented artists! The plush Proctacanthus is definitely one of my favorites, so she gets to sit on some of my favorite fly books! 😍 #FlyWeek #entomologistsareeasytogetgiftsfor

TIL that there's a #WorldRobberflyDay. To celebrate, here's Archilestris magnificus, a leggy tarantula hawk-mimic big enough to intimidate hummingbirds. Like many of Arizona's most sought-after birds, it's a Mexican species that rarely strays north of the border. www.inaturalist.org/observations...

Happy #WorldRobberflyDay, to those who celebrate! And why not celebrate this stylish, spectacular and deadly group of bugs! Here's a Beringian Sandpirate (Lasiopogon canus) that somehow found its way inside my house last summer... the commonest robber fly in the Yukon.

photographing assassin flies in nature has been a passion (scientific specimen more important to me than a photo though) - using Olympus SLR camera to capture Hoplistomerus nobilus (Loew, 1858) (Laphriinae) on slide film at Het Bad NR, Limpopo, South Africa in 2005

assassin flies are hard to catch - don’t give up, even when your net breaks in woody Fynbos vegetation in Swartberg NR, South Africa, the reward of catching a Hyperechia nigripennis (Wiedemann, 1830) for scientific research is wonderful

It’s #WorldRobberFlyDay! These amazing predatory flies are what first pulled me into the world of entomology. Today’s a great chance to shine a light on the incredible robber fly diversity across the Andes—there are still many taxa waiting to be described ...

At the @nhm-london.bsky.social we have hundreds of drawers of Asilidae, & receive requests from all over the world for either physical or digital loans
Check out these big un’s in the genus Hyperechia that I imaged for a recent request (these images are just for labels & size)

fossil assassin flies are amazing but also (sometimes) difficult to place taxonomically + phylogenetically
Burmese amber (100 mya) - Burmapogon bruckschi
Baltic amber (45 mya) - Protoloewinella keilbachi
Dominican amber (20 mya) - Schildia martini

Jason Londt photographed this beautiful Melouromyia natalensis (Ricardo, 1919) in his backyard in Pietermaritzburg in 2013 - he described genus (primarily distributed in eastern South Africa) in 2002 - many assassin-fly photos by him in Manual of Afrotropical Diptera

The @nhm-london.bsky.social recently hosted Greg Daniels - a superb Australian Asilidae expert
He moans that he is physically aging but the boy is bright as a button when it comes to going through the collection to figure out what’s what

Jason Londt loved field-work + collected almost in every corner of South Africa in search of assassin flies - major field-work also to Namibia, Malawi, Kenya, Côte d’Ivoire - 279 Asilidae specimens are now holotypes of new species he collected

I didn’t know #worldrobberflyday was a thing but Asilidae are one of my favorite Dipterous families. Here’s one in my office! Taken September 7, 1997 in Columbia, MO.
