Extracted from: LaBerge, W. E. 1963. New Species and Records of Little-known Species of Melissodes from North America (Hymenoptera: Anthophriadae). Bulletin of The University of Nebraska State Muesem, Vol. 4. Pp 227-242.
A long series of M. saponellus of both sexes, many captured in
copulo, were submitted to the author recently for determination.
Several females of M. saponellus were caught in copulo with males
of M. (Tachymelissodes) opuntiella, as well as others with males of
their own species. The author believes that interspecific "errors" of
this sort are not uncommon among bees. In fact, the author has even
observed bees of different genera seemingly in copulo in nature. The
new records listed below more than double the number of specimens
of this species available in collections.
