When it’s too hot to take photographs outside, I can always go down to my basement to photograph camel crickets (“sprickets” to many). I know, lucky me. But if you have a moist basement, you probably have them, too. The ones below are the introduced species (I think), Diestrammena asynamora, from Asia. They drive me nuts. So much so that I wasted time collecting ways to get rid of them (see my page, “Getting rid of camel crickets“, if you’re interested). The list is not 100% effective, as photographs attest, but at least I don’t have thousands of them anymore.

After agonizing over the identification of hornworm larvae for years, I’ve developed two tricks that I’d like to share. Tobacco hornworm (Manduca sexta) caterpillars have stripes (seven of them), so remember that by thinking of Lucky Strikes cigarettes. Horn is usually red or red-tipped, like a cigarette. Also, tobacco gives you dark teeth and lungs … and tobacco hornworms have black shadows on their stripes. Tomato hornworms (Manduca quinquemaculata) have eight chevrons (Vs), which you can remember by thinking of V8 juice, which is primarily tomato juice. Here’s the graphic you can share with friends who might have it wrong:
If you can, please spread the word … most of the tens of thousands of tobacco hornworm photographs on the internet are misidentified as tomato hornworms. Even Wikipedia page for tomato hornworm shows tobacco hornworm larvae (I’m working on it …). The problem is that tobacco hornworm eats tomatoes, and people with fancy cameras grow a lot of tomatoes.

Below are some photographs of Eastern boxelder bugs (Boisea trivittata) I took recently at the John Heinz National Wildlife Refuge in Tinicum, Pennsylvania. These true bugs are fun to watch — richly colored, morphologically variable (they go through numerous instars), and often shockingly gregarious. They move a lot, too, so rather annoying to get a decent photograph.
Mating pairs of red milkweed beetles (Tetraopes tetrophthalmus) are not rare (they can couple for hours at a time), but I thought this couple looked cute, in a worried sort of way. The half-lidded expression is because their compound eyes are bisected by their antennae. Beautiful beetles.
This golden-backed snipe fly (Chrysopilus thoracicus) landed in one of my bird baths and drifted around for a few minutes on the surface tension. I’m not positive, but I think I’ve seen them do this in past years, too. I wonder whether they are looking for mosquito larvae, or perhaps adults. These flies have predaceous mouthparts, so they clearly hunt something. Sure wish somebody would PCR the gut contents of these things and let me know. Anyone ever seen them take something down?
Here’s another one, albeit one with a damaged eye:
