What kind of antennae does a Plecoptera have?
The adult is mandibulate with filiform antennae, bulging compound eyes, two or three ocelli, and subequal thoracic segments. The fore wings and hind wings are membranous and similar except that the hind wings are broader; when folded, the wings partly wrap the abdomen and extend beyond the abdominal apex; aptery and brachyptery are frequent.
