This species is widespread, occurring throughout South and Central America, and widely adventive in the Pacific Basin (Menke 1986; Yamane et al. 1996; Willink and Roig-Alsina 1998). Numerous pub� lications have dealt with the biology of this species, including detailed studies of population dynamics in Jamaica ( Freeman and Jayasingh 1975a, b; Jayasingh and Taffe 1982). Its proclivity for nesting in pre�existing cavities is indicated by the common name “keyhole wasp” in Hawaii, and which has doubt� less aided its spread by humans. Wolcott (1941, 1951) published some flower visiting records in Puerto Rico.
