Osmia (Trichinosmia) are green metallic bees with long, branched mixed black and white hairs on the head and thorax. They range in body length from 9–10 mm (Michener 2007).
(modified from Michener 2007)
Osmia (Trichinosmia) can look similar to some species of O. (Melanosmia) but can be distinguished by abundant long, branched hairs on the head and thorax, and long hairs on their wings (Michener 2007).
In a study on Osmia (Trichinosmia), Parker (1984) observed O. latisulcata nesting in drilled holes in wood blocks. The cell partitions were constructed out of pebbles and masticated leaf pulp. This suggests that Osmia (Trichinosmia) nests in cavities; however, the types of cavities they use for nesting in nature is currently unknown.
Osmia (Trichinosmia) is monotypic with only one described species, O. latisulcata (Michener 2007).
Osmia (Trichinosmia) occur in desert or semi-desert areas in southwestern U.S. (Michener 2007).
