It seems that I get a lot of photos in the fall of insect species I've either not seen or not photographed before. This might be due to my willingness to poke around longer when it's not so hot.
Here are some of the insects I found in late August and September:

I think this is one of the broad-nosed weevils, an Asiatic oak weevil (Cyrtepistomus castaneus). The larvae of this species feeds on roots; adults go for the leaves of many woody plants, but seem to prefer oaks and chestnuts. You may also have seen these in your house.
It took me forever to get a good photo of this bug and almost that long to find anything that looked like it at BugGuide. I think this is one of the leaffooted family members, a Merocoris distinctus. I actually had to use a photo that just caught his bottom half to narrow down my search at BugGuide. This photo is the best of the bunch but it doesn't show the detailed wing pattern of a top view that allowed me to zero in on the genus Merocoris.
I got photos of several individuals of this butterfly species, the Carolina satyr (Hermeuptychia sosybius) on the same day. You can see a 2010 photo of the first one I ever saw, with its identity confirmed by some people at BugGuide.
On the 13th of September I found a bunch of insects in the goldenrod. You can see my blog post on these at Earthbytes: Amazing things you can find in the goldenrod.
