Several erigonine spiders (Linyphiidae) think the width of the opening of a purple pitcher plant pitcher is the perfect size to build a web. Not the safest web location, though.

Also S. purpurea may be used by the invasive Asian tiger mosquito, Aedes albopictus, as an oviposition site!

In solidarity with today's ICE OUT OF MINNESOTA blackout, MinnMax is donating $1 to the Immigrant Law Center of Minnesota for every share of this Bluesky post for the next hour.

It's true, after years of work, Jackson Means, myself, and the late Dr. Richard Hoffman compiled a 130-page tome of Virginia spiders in the journal, Banisteria. The journal dedicated the entire first issue to this work. We add over 140 new species records to the state to stand at 713.

I do not! Maybe an entomologist who specializes on true bugs can tell us.

I think it should be illegal to name your subdivision after the wildlife you displaced to build mcmansions

Bobolink Acres? Not anymore, you assholes, you made sure of that!

Some genera of Money #spiders Linyphyiidae are present as adults throughout the year, often with peak male activity in the #winter months (see chart for Walckenaeria acuminata). Whatever the weather, it's a good time to be out looking for them and their wonderfully distinctive headgear! #Christmas

Thanks, Marshal, that means a lot coming from you.

Unfortunately, even if many of those museums do become databased, many of their tiny spiders remain unidentified or identified at generic or family levels.

That's why guest curation is so important! If only I could do that 24/7...

Yeah! I reached out to my coauthor about that. We're planning a publication for it.

GBIF has 0 records and a Google Scholar search has 0 hits. I suppose it could be hidden in a collection somewhere (i.e., dark data) but certainly nothing published on it.

RE-DISCOVERY #4

Emblyna suwanea (Gertsch, 1946) (Dictynidae) was last collected by the great V. Wilton Ivie in 1943 near Sylvania, GA and hasn't been seen or collected since (82 years). We found a single male by vacuuming in the Okefenokee Swamp NWR along the Chesser Island boardwalk trail.

RE-DISCOVERY #3

Scotinella pennimani Platnick and ChamΓ©-VΓ‘zquez, 2024 (Phrurolithidae) was described just last year from specimens collected in 1967 (58 years ago). We found this lady in Okefenokee NWR on Trembling Earth Nature Trail just north of Stephen C. Foster State Park in SE Georgia.

RE-DISCOVERY #2

Our trip to Okefenokee NWR has resulted in another re-discovery of a long-lost species. Ceratinopsis sutoris Bishop & Crosby 1930 was last seen in 1927 (98 years ago!) and we collected several males and females. The species has a orange-red carapace with black around the eyes.

RE-DISCOVERY #1!

Our trip to Okefenokee NWR has already resulted in a re-discovery of a long-lost species. Ceratinopsis bona Chamberlin & Ivie, 1944 was last seen in 1943, 82 years ago. In addition to possessing genitalia that match the descriptions, their black tibia IVs are also diagnostic.

Yeah, but like, is it really Centromerus? That genus has not been revised. It would be interesting to see genetic data.

Day 4 of our Okefenokee NWF collecting trip took us to Mixons Hammock east of Stephen C Foster State Park. We canoed the two miles and then sampled mossy patches and magnolia litter in cypress swamps. Not the most productive, but we found many linyphiids for study.

Day 3 of our collecting trip was to the east side of Okefenokee NWF (a 1.5hr drive around the southern edge) where we collected in swampy thatch/moss patches along the Chesser Island boardwalk. Found lots of erigonines, a pygmy rattlesnake, and a water moccasin. Didn't collect the snakes, though. πŸ™‚
