Shore bugs

Definition

A family of small, oval true bugs (Hemiptera: Saldidae), 2–8 mm in length, typically inhabiting shorelines, intertidal zones, and marginal vegetation of freshwater bodies, estuaries, and coasts. Adults and nymphs are predatory scavengers capable of leaping or flight; some species tolerate periodic submergence during high tides. The term occasionally extends to related families Ochteridae (velvety shore bugs) and Macroveliidae within the superfamily Leptopodomorpha.

Etymology

From habitat association with aquatic margins; "Saldidae" from type genus Saldula.

Example

Saldula pallipes, a common shore bug of European coasts, forages in the intertidal zone and survives high-tide submergence by trapping air bubbles beneath its body.

Synonyms

• Saldidae
• leptopodomorph bugs

Usage Notes

In strict usage refers to Saldidae; broader usage includes all Leptopodomorpha. Distinguished from water striders (Gerridae) by smaller size, more compact body, and preference for shorelines over open water surface. Overwintering strategy varies by species: egg diapause versus adult diapause.
