#FlyWeek #WorldRobberFlyDay Fossil head of a Lasiopogon robber fly discovered in a 16,500-year-old Arctic Ground Squirrel midden in Yukon, Canada. Several species of the genus are common in the region today. See doi.org/10.4039/tce....

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...

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

Almost forgot #WorldRobberFlyDay but luckily reminded by @flygirlnhm.bsky.social. Here's the puparium of Laphria flava (Bumblebee Robberfly) collected from a pine log in Abernethy Forest a few years back. @dipteristsforum.bsky.social #diptera #ento #macro

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)

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....

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

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

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

Another fine hirsute Robberfly for #WorldRobberFlyDay, described by Jason Londt - the whole lateral image of Sisyrnodytes dasykylon Paratype, NHMUK014034877
This gets its name from the Greek dasys (thick with hair, shaggy) & kylon (parts below eyes). (Big mystax with extra setae)
