Abstract

Nests of Centris segregata Crawford are described from earth banks in slightly disturbed dry forest habitat in Costa Rica. Nests contain 1 to 3 burrows that originate in a chamber near the nest entrance. Each burrow has 1 to 11 urn-shaped cells arranged in a linear series. Cell caps have a hollow central process and are slightly recessed. In many burrows a short, uncapped, partly provisioned cell is placed above the last fully provisioned cell. Normal males and females were reared from the same nests, but only beta males were reared from some nests. Natural enemies include the anthophorid bee, Mesoplia rufipes (Perty) and the bombyliid fly, Anthrax cintalapa Cole. The diverse nesting habits of species of Centris are discussed in relation to the subgenera.
