White-zoned Furrow Bee - Lasioglossum leucozonium

Alternative names
Lasioglossum similis

A rather large, robustly-built Lasioglossum with conspicuous white tomentose patches on the sides of tergites 2 to 4 (which form complete bands when the abdomen is distended). The hind tibiae have a dark pollen brush. Females closely resemble those of L. zonulum but has a more densely-punctate first tergite, a less subquadrate head and greyer hairs on top of the thorax. Males are more easily distinguished by the divergent ridges on sternite 6. They have the hind bestiaries pale, but the remaining tarsal segments dark.
