There are 14 names in this directory beginning with the letter C.
campodeiform
Larval body type often called crawlers. Elongated, flattened body with prominent antennae and/or cerci; thoracic legs adapted for running.Example: lady beetle larva

cement layer
Layer of epicuticle that protects the wax layer from heat or abrasion.

cerci
Paired sensory appendages on the rear-most segments of some "primitive" insects. In some cases, they may also serve as weapons or copulation aids.

chorion
The protective "shell" of protein covering the insect's egg that is secreted before oviposition by accessory glands in the female's reproductive system.

coronal suture
Suture along dorsal midline of head; runs backwards from the vertex along the top of the head

coxa
The basal segment of the leg, by means of which it is articulated to the body

cuticulin layer
The innermost layer of epicuticle that is composed of lipoproteins and chains of fatty acids embedded in a protein-polyphenol complex.
