My first article was published in the Archives of Natural History! It is about The Naturalist’s Library, a popular forty-volume book series published in Edinburgh from 1833-1843 by William Home Lizars and Sir William Jardine. @sochistnathist.bsky.social
The best way to start the day- with a lovely two-tailed swallowtail…!
"A New Challenge to Species Delimitation: Remarkable Genomic and Ecological Diversity in the Butterfly Melitaea diamina" has been published! Read it here: onlinelibrary.wiley.com/doi/full/10.... #PublishedArticle @WileyInResearch
Museum Collections 🔬 Secret Morphology Lepidopterists can often look at butterfly and moth wing patterns to help identify them, but not always. They sometimes have to rely on – genitalia dissection. Read about this with our McGuire Center: www.floridamuseum.ufl.edu/mcguire/news...
Peck’s Skipper finally showed up in the garden. Their caterpillars can develop in nonnative bluegrass, and other native grasses.
So, know it or not, today is your lucky day! You are one of the first humans to see the fully-grown caterpillar of the undescribed Hypsocompe species! They have been happy feeding on a lot of plants, but at the moment seem to prefer the organic romaine from Whole Foods… 🐛😁
The hills are alive with the sound of vibrating keratin segments! Rattlesnakes, like this defensive Prairie Rattlesnake (Crotalus viridis), employ aposematic signaling to warn nearby threats, like coyotes, bobcats, and passing hikers, of their deadly presence. Be vigilant out there!
It was a long hot day, but in a majestical place that is poorly surveyed for butterflies. AND we found our target: a very poorly known metalmark (Apodemia sp.)!
This anglewing butterfly is very rarely seen because it basically never visits flowers or damp ground- it is a sap feeder. Endemic to Colorado’s Front Range: Polygonia oreas nigrozephyrus Douglas County, Colorado

Found a new favorite place! Actually found it last year, but a bit too late in the season to see it at its summertime best. It’s in the greater Sangre de Cristo range of southern Colorado… It was a butterfly paradise!
The amazing Chryxus Arctic, a biennial butterfly which caterpillars take two years to mature, eating sedges and grasses. Thus the adults only fly on even years.
Don’t bother going up into the Wet Mountains. Ugly terrain, no good views at all. Just stay away, ok thanks!
West Spanish Peak in southern Colorado is one of the most breathtaking features in the southern Rocky Mountains. Planned for a week around the weather forecast, for the perfect day up there, and got it yesterday!
🚨HOLY *&^$!🚨 @andybugguy.bsky.social LOOK WHO I FOUND! Abbot Cr. Rd. today! I got ONE photo! Shocked it's one GOOD photo! I had no idea who they were, just, "I have NEVER seen that skipper before!" Everyone who isn't Andy - this is an Arctic Skipper (Carterocephalus mandan) 1/2 #inverts
OH HERE WE GO SHE LAID A PILE OF EGGS!!!!
Andrew Warren@andybugguy.bsky.social · 3mo agoThis absolute stunner is an undescribed species of Hypsocompe, known from just a few specimens. There is only one other record from Colorado (Baca Co.), thus, this is the northernmost record for the species (see alt text). Found under the sheet this morning by @nunesnaturalist.bsky.social !

Southeastern Colorado remains absolutely parched, with almost no butterflies at the moment, but we’ve been finding a lot of really cool moths!

Abantiades hydrographus - Western Rain Moth Autumn rain and storms overnight brought this stunning Rain Moth to our Perth Hills moth light. She was big, ~80mm in length, and so beautiful! Such an honour to see these amazing moths. #teammoth #ausinverts #wildoz #Lepidoptera #inaturalist
A very badass fly with feathery legs. Genus Porphyrochroa
There are 214 Democrats in Congress. Where the fuck are the rest of them?

Look who showed up at my lights last night- a full SEVEN WEEKS earlier than the previous early date I have found it here...!!! Spring is springing way too early here along Colorado's parched Front Range... Glover's Silk Moth- Hyalophora gloveri

Yes- a very small moth, smaller than anyone realized. Very easy to overlook! As soon as I had it in the vial I knew what it was- since folks around here have been looking for it for decades… Now that it’s pinned, I can verify she’s a female- the holotype and only other known specimen is a male!
Cosmodes elegans - Green-blotched Moth These lovely moths are relatively frequent visitors to our Perth Hills garden but it’s lovely to see them every time! These moths are native to Australia and can be seen in most areas except the NT. #teammoth #ausinverts #wildoz #Lepidoptera #inaturalist
Today's bingo card definitely did not have "rediscover one of North America's rarest moths" on it today, yet here we are, on Feb. 6, in Colorado! www.inaturalist.org/observations...

Hey bsky! I’d like to share some cool work I recently coauthored that integrates entomology, paleontology, and German cultural history. 🔶🐜⚡️ We discovered a fossil ant in the amber collection of Johann Wolfgang von Goethe! Read on for a delightful story of #museomics and #collectomics. >> 1/
