Crickets
Crickets are black or brown insects over 13 mm long. They have long antennae, two compound eyes and grinding mouthparts. They have two pairs of many-veined wings on the thorax. The forewings are fairly tough. They protect the membranous hindwings, which are folded in a fan shape when at rest. Of the three sets of legs, the hindmost legs are the most noticeable, since they are adapted for jumping. Their femurs are particularly strong. Crickets have two sensory appendages called cerci at the tip of the abdomen.
Females have an ovipositor, a long cylindrical egg-laying organ, between the cerci.
