- Large body size
- Membranous wings
- Three ocelli form a triangle on top of head
These insects are noticed by their membranous wings, short antennae and three ocelli that form a triangle between the compound eyes. They range in color, a possible adaptation to blend in with their environment. You can often hear the male cicadas sing in a high pitch, pulsating tone. Cicadas lay their eggs in slit twigs of trees. Between the laying of the eggs and feeding habits, they can do considerable damage to young trees and nursery stock.
