Philanthidae

Definition

A family of solitary wasps in the superfamily Apoidea (Hymenoptera), comprising approximately 1,167 described species in eight genera, with the majority placed in the genus Cerceris. Philanthid wasps are predatory, typically provisioning nests with paralyzed beetles or other prey for their larvae.

Etymology

From Greek philanthrōpos, 'loving humanity' (the type genus Philanthus was so named by Fabricius, possibly alluding to their bold, unafraid behavior around humans).

Example

Cerceris fumipennis, a philanthid wasp, specializes on metallic wood-boring beetles (Buprestidae) and has been employed in citizen-science surveys to detect invasive emerald ash borer populations.

Usage Notes

Formerly treated as a subfamily (Philanthinae) within Crabronidae; elevated to family rank in recent phylogenetic revisions of Apoidea. The family is morphologically diverse but unified by larval provisioning behavior and specific wing-venation characters. Not to be confused with philanthropist (human charity), despite shared etymology.
