Bank of ephemeral stream at night. Looks like Chlaenius, but I haven't seen black spp here before.
Collected at UV light sheet rigged up with 2 Entoquip lights (365 & 395 nm)
Not 100% sure about this one, but ID based on Bousquet’s (2010) key:
-Size <6 mm
-Mentum sides not very sinuate
-Setae under each 5th tarsomeres
-Posterior angles of pronotum obtuse
-Caught in a Carex/Scirpus wetland
Quite uncommon species in the Northeast according to LeSage & Savard (2018): https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=web&cd=&ved=0CAIQw7AJahcKEwj4vJHrhoX_AhUAAAAAHQAAAAAQAw&url=https%3A%2F%2Fstatic1.squarespace.com%2Fstatic%2F5731421e07eaa0ea485cadae%2Ft%2F5e97cd3b1d366e1fec0c5b41%2F1587006782406%2FFABRERIES_2018oct.pdf&psig=AOvVaw0ptptTm7F6krdKxeqACjXM&ust=1684711847334685
Part of a wreak caused by two days of east winds pushing insects flights out over the ocean.
A larva that hatched last night, from an egg laid by the green/blue dark coloration C. wilcoxi (https://www.inaturalist.org/observations/160809307)
Along margin of small pond with willows and dense ground cover of sedges.
If you tag as granulatus, please read on.
According to Lindroth:
“Black, upper surface and presternum as a rule pronouncedly metallic, varying from bronze to copper or GREEN. In elytral sculpture it resembles granulatus: three rows of strong tubercles alternating with two unbroken (though + winding) ridges; but the SUTURAL RIDGE IS LACKING. The margin is feebly serrate behind the shoulder (much less so than in serratus), hardly sinuate before apex. The prothorax is more convex than in granulatus, with less flattened sides. The 3 basal antennal segments are COMPRESSED, almost keeled above…”
“A northern but not arctic species with transamerican distribution, though very rare in the west... A rather hygrophilous species, confined to open, + moist ground with rich but moderately high vegetation. Often in Carex bogs.”
Location obscured for privacy. Exact location not given.
Sifted from Betula and Populus leaf litter near a sand pit.
Attacking a terrestrial planarian on bank of creek.
The beetle repeatedly bit the planarian, cutting through the worm in different places, before retreating and cleaning off mucus that had covered its mouthparts and front tarsi. Eventually, the beetle cut off the planarian's posterior and began eating this while the rest of the worm escaped.
Odd colony of fungi I saw back in December. Think it was growing on something (decomposer?).
A. Coleoptera: hard outer elytra covering wings.
B. Adult.
E. Overcast. ~60F.
A few better pics of this little population that lives on the slightly wet clay along the pond (shade side). They keep moving
A large ground Beetle, found under a rock near the stream.
Amazing little beetle. Hadn't realized how beautiful they are as they were so small. Nice little population close to the pond
1cm long; came out of a discarded beer can; fast moving once it was done cleaning its antennae
Walking around near a trail a bit west of the main set of Loop Road houses.
I set up two sheets at Pinecrest Campground (no campers) in Big Cypress National Preserve for blacklighting. I originally tried Mitchell Landing Campground nearby but all of the spots with electrical sockets were taken by campers so I went to Plan B and only used my DJ blacklights connected to USB powerpacks.
1: Pinecrest campground, very close to the gate and in the tunnel of trees before the open area. 2 DJ blacklights running from ~11:00PM until ~12:30AM and then the batteries died. I put on a new battery later than I should have (around 2:15AM) but I was busy photographing insects at the other sheet.

2: Pinecrest campground, sheet tied to large sign and tree facing open area with just one DJ blacklight connected to USB powerpack.

In addition to the blacklighting, I also set up a sheet (no lights) under an oak with some low hanging branches that I was able to whack with a fallen branch I found. I didn't put a ton of effort into this but still saw some cool barklice and other critters.

All of my observations from tonight including a little bit of walking around with a flashlight looking for spiders/insects:

Here's a video showing the DJ blacklights in action at the Pinecrest campground (Big Cypress) from Summer 2019: https://youtu.be/tavmTa7WoPk
Info about the cheapy DJ blacklights I used, great for getting started with blacklighting: https://www.inaturalist.org/journal/damontighe/11836-diy-moth-light

Looks like a beetle larvae. Maybe even fungus ridden.
