Background
Xylocopa (
Xylocopsis) are small, robust bees, 10-15 mm in body length. They have a dark brown to black
integumentintegument:
a tough, protective outer layer
that is somewhat reflective. They have brown, moderately thick,
pubescencepubescence:
short, fine hair
and their wings are a medium to dark brown with violet reflections (

Berkeley and Los Angeles: University of California Press, 365 pp.). They seem to be territorial, attacking invaders, including birds. They have been observed rubbing their
metasomametasoma:
the posterior part of the body
on branches they land on. This is likely to mark their territory with pheromones (
