Note: Introducida desde África, posiblemente en el siglo XIX, en las Antillas, desde donde pasó a Estados Unidos (Eickwort, 1971; Krombein et al., 1979; Mitchell, 1980). Es interesante destacar que la localidad tipo de esta especie es una zona donde fue introducida (Santo Domingo) y no su área natural de origen (Genaro, 2007)

(We examined the specimens recorded by Wolcott (1948) as “M. insularis Cresson” that were identified by Karl V. Krombein (located in MEBT-MC and UPRM), these are actually M. concinna. Wolcott (1936) apparently misunderstood the name Megachile singularis Cresson mentioned in Ashmead (1900) interpreting it to be Megachile insularis Cresson, distribution).
