A long, glossy black snake stretched across the patio, climbing a shed wall, or vanishing into the woodpile is one of the most common — and most alarming — reptile sightings of late summer, right as this year’s hatchlings start turning up. The good news is that the big black snake in most yards is a harmless rat snake or black racer, not something to fear. Here is how to tell the two apart, separate them from the venomous snakes people worry about, and understand why a black snake around the yard is usually a sign of good pest control at work.

On a warm late-summer night a huge, prehistoric-looking insect thumps against the porch light — several inches long, with soft gray wings folded over its back and a pair of enormous, curved pincers on the male that look like they belong on a beetle three times the size. It looks like something that should be dangerous, but the eastern dobsonfly is one of the more harmless giants in the insect world.
