Apianthidium resembles Trachusa due to similar body form and size. However, Apianthidium can be differentiated from Trachusa by the distinctly hooked apices of the hind tibial spurs, and the middle tibia as broad, or nearly as broad, as hind tibia (Michener 2007).
There are no known invasives.
Floral associations are unknown.
