There was snow last night with the ground temperature above freezing, then cooling, so snow stuck to vegetation, especially sweetgum balls on trees and on roads. I found the effect visually interesting.

Anthrax aterrimus (length 13 mm, wingspan 32 mm, male?)
bugguide.net/node/view/96007
Identification notes in comments on an image of a fly from the same location at:
bugguide.net/node/view/63620
"This specimen and the one in the linked photo appear to be Anthrax aterrimus. This species and the Florida population of A. georgicus are the only eastern Anthrax with entirely black wings. They can be separated with a clear view of the side of the thorax, but I think the range is sufficient for these photos."

This beautiful wasp mimic syrphid was buzzing noisily about a tree hollow filled with rotting vegetation at Eno River State Park north of Durham NC. It kept returning to the site, but I never saw it enter. I've seen them seek out rotting compost in the past. (Larvae are aquatic "rat-tailed maggots" that live in wet rotting vegetation--see BugGuide account.) The large eyes suggest this is a male (comparing other images and comments at BugGuide), so perhaps it was in search of females. One of the frames here on iNaturalist shows the cavity of interest.

This firefly was found flying around in a Durham NC suburban yard during the day. The dark protective elytra on the beetle's back are modified forewings. The functional rear wings of this beetle are mostly hidden here--they are just visible folded under the elytra where they meet in one shot. Happy Wing Wednesday!
This genus of fireflies has reduced or absent light organs as adults. A small light organ is visible in the ventral view of this one. This might be a female, as its antennae are less serrate than those of others I have found.

This moth has such a great cryptic posture with the abdomen upraised, resembling a twig, I guess. However it really makes them stand out when they come to lights, as this one did several years ago in Durham, NC. In one image, I was able to get a view of the "face", with a large eye and projecting palpi, which give it a comical expression. Happy Moth Monday!

This BRF (Big Robber Fly) is:
Red-footed cannibal fly - Promachus rufipes (female)
bugguide.net/node/view/3027
These things are large. Length from head to base of ovipositor is about 26 mm, to tip of ovipositor about 30 mm. This individual was found at the lighted wall of a gas station north of Durham NC in the early morning. It was captured and chilled for a photo session, then released in more appropriate habitat. Location noted is site of capture.
I took the opportunity with a captive to take some detail shots of the face and legs. I was pleased to be able to look closely at the antennae, tarsi and pulvilli (foot pads).

Hooded Grouse Locust - Paratettix cucullatus
bugguide.net/node/view/199273
I've seen this species several times on rocky spillways and such--it is superbly camouflaged on rocks. This one was on rocks in the Little River at Mitchell Mill State Natural Area in Wake County, North Carolina. Lighting was quite difficult, with lots of glare. This was definitely a day for a polarizing filter, but I did not have one along. Some distracting specular highlights in the background were cloned out, but this did not alter the image of the critter.
Notes on ID from BugGuide and references on that page. (I wrote much of that page based on the references noted there.)
-Lobes on middle femur--a characteristic of this species.
-Long wings--presence said to be a character for this species--many other species in this family have predominantly short-winged forms.
Location is approximate. We hiked up the stream for a ways, but I did not have a GPS with me.

I've seen this species several times on rocky spillways and such--it is superbly camouflaged on rocks. Here it was on the spillway of an old farm pond in Chatham County, North Carolina. This was taken in 2005 with my first DSLR, a 6 megapixel Canon 10D--an excellent camera. I recently reprocessed the images more carefully than my initial efforts.

The biology of this group is very strange. They are usually associated with ponds and eggs are sometimes laid in water. Adults have been reported to dive into water and swim away--underwater--as an escape. They are of little economic importance, so have not been studied much compared to other orthoptera; as a consequence they are difficult to key. This one was identified by an expert on BugGuide. Many species in this group have short-winged adult forms, but this one seems to be long-winged, usually.
Happy Wing Wednesday!

Image identified by an expert at:

as Diogmites angustipennis.

Looking at records on BugGuide and here on iNaturalist, I am doubting that species ID a bit. Seems like angustipennis is not otherwise recorded from the Carolinas. I will move this up to genus level--maybe somebody here will have a firm idea on the species.

Female flightless tussock moth found on twig/foliage of Willow Oak, Quercus phellos. She might have laid eggs under that mat--I am not sure. I put her out in a ventilated enclosure one night to see if a male was attracted, but no luck. This appears to be a tussock moth, Orygia species (Erebidae), and not a superficially similar cankerworm (Alsophila - Geometridae).

Orgyia species, female, about 16 mm length.
