Hebridae

Definition

A family of minute semiaquatic true bugs (Hemiptera: Gerromorpha) commonly known as velvet water bugs. Hebrids inhabit mossy margins of ponds, streams, and other vegetated wetlands where they prey on small arthropods. Unlike the surface-skating Veliidae and Gerridae to which they are related, hebrids typically walk or run across water surfaces rather than skate, and represent the smallest members of the infraorder Gerromorpha.

Etymology

From Greek hebraios, of uncertain derivation; the family was established by Amyot and Serville in 1843.

Example

Hebrids such as Hebrus ruficeps are frequently collected by sifting saturated moss along pond margins, where their tiny dark bodies contrast with the pale velvety pubescence that gives the family its common name.

Synonyms

Usage Notes

Hebridae is treated as plural in form but singular in construction when referring to the family; individual species are hebrids. The family is distinguished from Veliidae (small water crickets) by their more robust build, shorter middle legs, and characteristic walking locomotion on water. Hebrids are often overlooked due to their minute size (typically 1.5–3 mm) and cryptic habits among dense vegetation.
