There are two types of hymenopterans that folks call 'yellow-jackets". Paperwasps nest above ground in nests that are single-shelved. The wasps are about 3/4 inch to 1 inch long. They are banded with black and yrllow. Sometimes the colors fade so the banding is not bright. They are very slender for their length. When excited and just before they attack, they will walk agitatedly about the nest with their wings outstretched and vibrating. When they're calm, they move more slowly and keep their wings folded. The nest usually has a half-dozen to 20 insects. It starts with a queen and then her brood population expands until frost.

The other wasp called a yellow-jacket is also called a ground hornet (hornets are wasps, too). They billed assymetrical, multi-tiered paper nests underground. They like rotted roots or stumps or boards that have virtually disappeared, into which they dig. They are under a1/2 in in length and have some bristles on their abdomen. They are brightly colored with black and yellow bands. They are stout rather than slender.

Both kinds of wasps are omnivores. They hunt other live insects and will also eat carrion. They love pear, apple and fig trees where they hunt-down and sting little boys for the pure joy of inflicting agony (that last is from painful memory).
