Calliopsis zebrata bobbae
(Rozen, 1958)
A of mining bee in the Andrenidae, known from sandy soils in Colorado and adjacent regions. Males are notably larger than typical for the Calliopsis and exhibit distinctive , hovering persistently over nesting sites. The subspecies was described by Rozen in 1958 and is part of the diverse native fauna of western North America.

Identification
Males are distinguished from other Calliopsis by their relatively large size; most Calliopsis are very small. Males fly relentlessly over bare sandy ground where females nest, landing only briefly. Females are ground-nesting mining bees. Separation from other of C. zebrata and from requires examination of morphological details not reliably visible in field observations.
Habitat
Sandy soils suitable for ground-nesting; found in plains and areas with bare earth patches.
Distribution
Colorado; western North America.
Life Cycle
Ground-nesting; females construct burrows in sandy substrate. Males aggregate in over nesting areas.
Behavior
Males exhibit persistent hovering over nesting sites, landing only momentarily. This creates the impression of swarming , though the is solitary.
Ecological Role
; visits flowers for nectar and pollen. Contributes to pollination services in prairie and plains .
