Trachusa zebrata
(Cresson, 1872)
Zebra Resin-Leafcutter
Trachusa zebrata is a solitary in the Megachilidae, commonly known as the Zebra Resin-Leafcutter. It is native to North America and belongs to a characterized by resin-collecting . Like other members of Megachilidae, females construct nests using collected materials and provision with pollen and nectar for their offspring.

Identification
Members of Trachusa are distinguished from other Megachilidae by their use of plant resins in nest construction, combined with leaf or petal pieces. The specific epithet 'zebrata' suggests striped patterning, though this has not been explicitly documented in available sources. Similar resin-using bees in related genera such as Anthidium may be distinguished by body shape, resin source preferences, and geographic distribution.
Habitat
Specific preferences for T. zebrata are not documented. Related Trachusa typically nest in pre-existing cavities or exposed locations on rocks or vegetation, utilizing resins and plant materials for construction.
Distribution
North America. Distribution records are sparse, with 15 observations documented in iNaturalist as of the data cutoff.
Diet
feed on nectar from flowers. Larvae are provisioned with pollen and nectar collected by females.
Life Cycle
As a solitary , females construct individual nests without cooperative social structure. Nest are provisioned with pollen and nectar, and an is laid on the food mass. Larvae develop within sealed cells, with occurring before . Specific timing and details for T. zebrata are not documented.
Behavior
Females collect plant resins and leaf or petal pieces to construct and seal nest . This resin-leafcutter is characteristic of the Trachusa within Megachilidae. Males may patrol nesting areas, as observed in related solitary .
Ecological Role
. As with other native bees, T. zebrata contributes to pollination of flowering plants during foraging activities. The also serves as a prey or resource for cleptoparasitic bees and other natural enemies, though specific associations are not documented.
Human Relevance
Native bees including T. zebrata contribute to services through pollination of wild plants and potentially agricultural crops. No specific economic importance or management practices have been documented for this .
Similar Taxa
- Anthidium speciesAlso collect plant resins for nest construction, but differ in body shape, resin sources, and typically use resin exclusively rather than combining with leaf pieces
- Megachile speciesShare Megachilidae and leaf-cutting , but use leaf pieces alone without resin incorporation; nest in pre-existing cavities rather than exposed resin constructions
- Trachusa species share resin-leafcutter nesting strategy; specific identification requires examination of morphological details not available in current sources

Taxonomic Note
The Trachusa is placed in tribe Anthidiini, a group of bees commonly known as 'wool-carder bees' or 'resin bees' based on their nest material preferences. The 'Zebra Resin-Leafcutter' reflects the combination of resin collection, leaf cutting, and likely striped appearance implied by the specific epithet.
