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.
This is the same individual, and adjacent frame, as this image on iNaturalist, which came in through EOL/EOL group on Flickr:

More shots of this fly from Iowa in 2011. Looking at the sequence, I realize I had combined two different individuals into one iNaturalist observation, so am fixing that! This one has a narrow abdomen--might be a male, while the other might be a female.

Hooded Grouse Locust - Paratettix cucullatus (measured body length 15 mm)
bugguide.net/node/view/199273
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!

This big robber fly was found early in the morning near a lighted window at a shopping center some years ago. I reprocessed these images recently and am posting much larger, I hope improved, versions now. HFDF!

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).

First appearance of "frost flowers" on stems of my cultivated Verbesina virginica during an early cold snap, 11/13/19. This is about the earliest I can recall seeing them--usually the first week of December is more usual for a hard freeze.
Botany note: this plant is native to the southeastern US, its range perhaps extending to just south of Durham NC. This batch is cultivated--from seed I collected in Tennessee years ago. (I thought it was ironweed, Vernonia, when collecting the seed.) This turns out to be a good insect-attracting plant, though it is not as attractive as ironweed, and it spreads a little aggressively in my yard. The frost flowers in the fall have been a pleasant side effect.

I found this large wasp moribund on the side of a car on a chilly fall morning. I knew immediately this was not something I had seen previously. I posed it for photos while it was still alive, but it never recovered. The curly antennae confused me, and I was thinking it was a spider wasp (Pompilidae), but an expert on BugGuide set me straight--it has a long abdominal petiole characteristic of sphecids. It appears to be rather uncommon, as there are only a few records on BugGuide.

I had a few of these flies on cultivated native aster right after the late October heat wave but before the November cold snap. They are lovely bee/wasp mimics. I wonder about the striped thorax--I do not recall any hymenoptera with that pattern, but maybe it is just a bold, scary look. The genus name Helophilus appears to be from Greek roots helo- (marsh) + philus. The larvae are aquatic, feeding on decaying vegetation, according to references.

This very fresh, bright, moth had been feeding on privet, Ligustrum species. It was very flighty while feeding. There was a brief period of cloudiness, and it stopped to bask, finally allowing me to approach closely. The blue marks are said to be seen only when the moth is fresh. The tufts of orange scales on the legs are thought to mimic pollen baskets of bees. (I read that somewhere, but cannot remember where!)
