Trachusa cordaticeps
(Michener, 1949)
Cordate-headed Resin-Leafcutter
Trachusa cordaticeps is a of resin-leafcutter bee in the Megachilidae, first described by Michener in 1949. It belongs to the tribe Anthidiini, which includes bees that construct nests using plant resins and leaf pieces. The species is distributed across Central and North America. Like other members of its , it likely nests in pre-existing cavities and uses resinous materials for construction.

Identification
The specific epithet "cordaticeps" (cordate-headed) suggests a -shaped structure that may aid in distinguishing this from . Members of Trachusa can be recognized by their robust body form and the presence of scopal hairs on the for pollen transport, characteristic of Megachilidae. Precise identification requires examination of morphological details including head shape, clypeal structure, and male genitalia.
Distribution
Central America and North America. GBIF records indicate presence in Middle America and North America.
Ecological Role
As a member of Megachilidae, this likely functions as a and contributes to pollen and resin collection for nest provisioning. The tribe Anthidiini is known for using plant resins in nest construction, which may influence local plant resin availability.
