Ornate pit scales

Definition

A common name for scale insects of the family Cerococcidae (Hemiptera: Coccoidea), characterized by elaborate waxy coverings that form ornate, often circular or ring-like structures around the body. These coverings typically include a central depression or 'pit' and intricate marginal ornamentation, giving the mature female a distinctive decorated appearance. The family is relatively small and primarily tropical, with species often found on woody host plants.

Etymology

Common name derived from the ornate, decorative waxy coverings and the central pit-like depression characteristic of these scale insects.

Example

Species of Cerococcidae such as those in the genus Cerococcus produce conspicuous ornate pit scales on oak and other hardwoods, with the waxy covering forming a raised, lacy ring surrounding a central sunken area where the insect body resides.

Synonyms

• Cerococcidae

Related Terms

• scale insect
• Coccoidea
• wax covering
• test
• marginal filaments
• Hemiptera
• Sternorrhyncha

Usage Notes

Used as a vernacular name for the family Cerococcidae; specialists typically prefer the family name. The 'pit' refers to the central depression in the waxy test, not a geological feature. The ornate coverings are produced by the sessile adult female and serve protective and possibly humidity-regulating functions. Distinguished from other pit scales (such as some Asterolecaniidae) by the specific structure of the waxy covering and taxonomic placement.
