Definition
Anthophora urbana is a species of solitary bee belonging to the genus Anthophora within the family Apidae.
Overview
Anthophora urbana has been recorded in North America, with occurrences reported primarily in the eastern United States and adjacent regions of southern Canada. As a member of the genus Anthophora, it is typically a ground‑nesting bee that forages on a variety of flowering plants. The species is part of a diverse group of “anthophorine” bees known for their rapid flight and often striking coloration.
Etymology / Origin
The generic name Anthophora derives from the Greek words ánthos (“flower”) and phóros (“bearer” or “carrier”), reflecting the bees’ role as pollinators. The specific epithet urbana is Latin for “of the city” or “urban,” possibly referring to the habitats where the species was first noted or to a perceived affinity for disturbed or semi‑urban environments. The species was formally described by entomologist Ezra Townsend Cresson in 1869.
Characteristics
- Taxonomy: Order Hymenoptera; Family Apidae; Subfamily Apinae; Genus Anthophora.
- Morphology: Adults are medium‑sized (approximately 10–14 mm in length). They typically exhibit a robust, hairy body with a predominantly black or dark brown integument, often accented by lighter hair bands on the thorax and abdomen.
- Behavior: A. urbana is solitary; females excavate individual nesting burrows in bare or sparsely vegetated soil. Nests consist of a main tunnel with lateral brood cells provisioned with pollen and nectar.
- Phenology: The flight period generally spans late spring to early summer, though exact timing can vary with latitude and local climate.
- Foraging: Like other Anthophora species, A. urbana is a generalist forager, visiting a wide range of flowering plants for nectar and pollen. Accurate pollen preference data specific to this species are not confirmed.
