Reddit reviews Tracks & Sign of Insects and Other Invertebrates: A Guide to North American Species

Stream insects will still be around, if you can get the kids to brave the cold water. Do you have access to a kick seine or a couple of D-nets through your university? I have probably fifty resources related to taking kids in creeks and poking around and looking at what comes out.

Also, get yourself a copy of this book because it is an awesome resource for off-season bug-hunting.

What part of the SE? Just curious. You may find that the litter layer is still pretty active in November, if you're in a warm enough area.
