Exomalopsis Lissotera

''Exomalopsis'' is a genus of bees in the family Apidae. They occur in the Western Hemisphere ( Neotropical and Nearctic realms).Velez-Ruiz, R. I. and A. H. Smith-Pardo. (2013)

Biology

Bees of this genus build communal nests. Several examples have been documented in the literature. ''E. aburraensis'', for example, has been known to build its nest alongside the beekeepers' honeybee hives. It excavates a tunnel over a meter deep which then branches into many underground pathways that lead to cells where larvae hatch and develop. The California species ''E. nitens'' enters cracks in dry soil and digs chambers underground. There it creates a pile of food provisions and lays eggs on top. The larvae eat the food pile and then pupate.Rozen, J. G. and R. R. Snelling. (1986)

''Journal of the New York Entomological Society'' 94(4) 480-88. Both ''E. globosa'' and ''E. similis'' have been noted nesting in dirt roads made of gritty red clay. The gravid female piles food in a terminal cell and then molds it into a neat loaf. She lays an egg on it and then seals the cell to allow the larva to develop within.Raw, A. (1977)

Several ''Exomalopsis'' are associated with kleptoparasites, especially cuckoo bees. Kleptoparasitic cuckoo bees of the genera ''Brachynomada'', ''Nomada'', ''Paranomada'', and ''Triopasites'' have been found using ''Exomalopsis'' nests. The newly described cuckoo bee '' Nomada medellinenses'' moves into the nests of ''E. aburraensis'' and lays its eggs there.

Some species are hosts for parasitoid wasps of the family Mutillidae. ''E. solani'' is parasitized by the wasp ''Pseudomethoca bethae'' and ''E. fulvofasciata'' is host to at least two species of ''Timulla''.
