Cerococcidae

Definition

A family of scale insects (Hemiptera: Coccoidea) commonly known as ornate pit scales or cerococcids, characterized by elaborate waxy coverings that form pit-like depressions in host plant tissue. The family comprises 83 described species in 5 genera distributed globally, with adults typically sessile and feeding on vascular plant fluids through piercing-sucking mouthparts.

Etymology

From Greek keras (horn) + kokkos (berry/grain), referring to the horned or ornate waxy coverings characteristic of these scale insects.

Example

Cerococcus multipartitus, an ornate pit scale in the family Cerococcidae, forms distinctive raised waxy rims around its feeding site on oak leaves, creating characteristic pit galls that distinguish it from armored scales in Diaspididae.

Synonyms

• Ornate pit scales
• cerococcids

Related Terms

• Coccoidea
• Diaspididae
• Pseudococcidae
• scale insect
• test
• gall
• Sessile

Usage Notes

Distinguished from armored scales (Diaspididae) by the lack of a separable protective test and from soft scales (Coccidae) by the pit-forming habit and more elaborate wax ornamentation. The family is relatively small and taxonomically stable compared to hyperdiverse scale insect families. Identification relies heavily on microscopic examination of adult female morphology and wax secretion patterns.
