Any ideas as to what these things are?
Jk, catch a few of those things, they won't bite, even if ants, put um in pill bottle, etc.. Swarmers are mostly males a few queens. I dunno about swarm times in Sothern Ca, but ants tend to swarm in autumn more than termites. Both tend to swarm more on overcast days. Ants have a thin "wasp waist", termites don't have an apparent waist. Compare at joe's link, or just google image termites and ants. Take, or mail, a few to local University or county agriculture extension office. They can identify them. Some pest control companies will identify anything as termites--$$$$$. If caught in time, termites might just be $$$$.
Squerl, you can do same if you can catch bug. There is a kind of bug that, if I remember right, looks like your's but is usually covered in dust and stuff, even dust bunnies. Its name is even something like dust case, trash bug, dust bunny bug, or somethin like that, harmless. But try Hintz, he has identified insects from really blurry photos.
And why you pick such hard to spell name? My spel check has to work over-time as it is. Tree rat is easy to spell.
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
