Biology

Lasioglossum busckiellum has been recorded from flowers of Parthenium L. ( Asteraceae ).

Remarks

Lasioglossum busckiellum was described from the Island of St. Domingo, now Hispaniola, probably from the Dominican Republic. This species belongs to the Lasioglossum parvum species group, which includes bees also referred to as the L. tegulare species group ( Ellis 1914a; Gibbs 2009a). Wolcott (1948) recorded L. busckiellum from Puerto Rico based on specimens identified by Krombein and Sandhouse. Both L. busckiellum and L. parvum have distinctive punctation in the apical impressed areas of the metasomal T2–T3, which are absent in all L. parvum group specimens examined from Puerto Rico, including one identified as L. busckiellum by Krombein. Lasioglossum busckiellum has darker tegula than does L. parvum . Some specimens of L. enatum sp. nov. seem to have dark tegula suggestive of L. busckiellum .
