There's a part of my favorite haunt which occasionally spawns one or more of these silly Snootflies in my path. Didn't see many this year, but this little man put on a show.

No I need to make a fucking post about this because I just stumbled on this paper, and this is insane.
Going to be talking about and sharing images of various insects. You have been notified.
So y'all know fleas. The little parasitic insects.
Yeah. Those guys.
Well. This study did genetic analysis on fleas (and several other insects) to find out what these guys derive from. Because up to this point, fleas have been just these weird little things in their own order that are... somewhere??? in the Antliophora clade. Previous scientists have thought maybe they're some weird offshoot of Diptera (true flies), because they do actually have vestigial little wing casings.
But this study, and the genetic analysis they did, revealed that fleas are not especially similar to Diptera. They're actually most similar to Mecoptera. Scorpionflies.
That's right. These guys.
Which is completely and utterly insane to me. You're telling me these big, super unique and specialized, weird-ass bugs, somewhere down the line, created an offshoot of these tiny little insects that lose their wings in favor of hopping around, that parasitize vertebrates and feed on blood? Scorpionflies did that??
Idk this is just. So so interesting to me. The Big wide beautiful world of entomology.
Here's that study. I think you'll have to make an account on the site in order to read it (though I can also just send any interested folks the file I downloaded, since I successfully made an account), but it is SO fascinating.
Hi, hello, sorry to bother you! If you take requests and they are currently open, could you maybe identify any DNA strings in the song The Summoning by Sleep Token? 🤓 The frontman is a massive nerd and active lurker, and I feel like he'd get a kick out of something like this. Please and thank you 🙏

Closest match: Panorpa germanica genome assembly, chromosome: 1
Common name: German Scorpionfly
Scorpionflies (order Mecoptera) in genus Panorpa
Top two are female; bottom is a male
Pennsylvania, US
These cool-looking insects are called scorpionflies because the males of many species (like the one above) have a large bulb at the end of their abdomen that looks like a scorpion's stinger. Despite the intimidating appearance, their "tails" cannot sting and are only used for mating.

In fact its a snow scorpion fly a strange little insect, distantly related to fleas. These bugs are active in much cooler temperatures then most other insects sometimes into the middle of winter if the weather is cool enough. They feed on moss and can be quite locally common if you find the right area. If they feel threatened they will launch themselves backwards and then play dead for a couple seconds. I watched them do this several times well i was photographing them. Very cute.
Anyways I'm gonna try to use this more often. hoping to do maybe a post a day for this week we shal see.
Fast Fauna Facts #24 - Snow Scorpionfly (Boreus hyemalis)
Family: Snow Scorpionfly Family (Boreidae)
IUCN Conservation Status: Unassessed
Most scorpionfly species are winged and (in males) possess long, flexible tails resembling scorpion stingers, but in this rarely-spotted terrestrial scorpionfly native to cold regions of northern and western Europe neither are present. In place of their wings Snow Scorpionflies have developed powerful hindlimbs that allow them to jump impressive distances (earning them the alternative name of "snow fleas" in parts of their range,) and as adults of this species are active only for a brief period in their range's late autumn/fall and early winter they use this ability to move across snow and hard frozen ground in search of food (mainly rotting plant matter, as the scarcity of other insects during the winter makes the carnivorous diet seen in most scorpionflies impractical.) Female Snow Scorpionflies (which can be distinguished from males by the spike-like ovipositors/egg laying "tubes" that extend from their abdomens) lay their eggs among dense moss, with their larvae feeding on moss until they're large and old enough to burrow underground and undergo metamorphosis.

The man, the myth, the legend! I love scorpionflies sooooo much! I’d been trying to get a picture of one for a while, and I was finally successful, even getting a video!
Despite their name, they are neither flies nor scorpions. What looks like the ‘stinger’ of the scorpionfly (and what gives them their name) is actually the male’s aedeagus (male reproductive organ of insects), and so the females do not have one. They are mostly scavengers, and members of Panorpa are known for stealing prey from spiderwebs to eat it themselves.
