Amegilla chlorocyanea

Males are approximately 11mm long, with females being a little larger at around 13mm long. The eyes are large and grey-green. The antennae are black and the tongue is long. The labrum, mandibles and supraclypeal areas are pale yellow. The clypeus has a pale yellow upside-down T-shape, creating two black facial stripes that are much wider on the female. The areas around the eyes are black, with predominantly pale yellow hair. The thoracic hair is mostly ginger or brown on top and white underneath. The metasoma has white hair bands with metallic blue-green iridescence, but in about 10% of specimens the bands are orange. Females have a large spot of pale hair on the end of the abdomen, with a hairless black triangle just above it. Males have notches of black hair on the end of the abdomen. The legs have black hair closest to the body and mostly white hair on the outer parts. The outer leg hairs have a blue/green iridescence, which is a diagnostic feature of this species, however, it's not always visible in photos. Females have a short black streak of hair on the hind leg, which is not present in males.

Amegilla chlorocyanea is endemic to Australia, where it can be found across the mainland, particularly in the arid and temperate areas. It has also been recorded on several offshore islands, including Kangaroo Island, Barrow Island, Enderby Island and the Neptune Islands. A specimen was collected in Tasmania in 1948, but it's believed this was part of a failed introduction.

This is a solitary species, however, females generally nest in groups. The nests are up to 100mm long, and are dug in sheltered positions in the ground. Common nesting locations include creek banks, under houses, dry mudbanks and old mortar or sandstone. A completed nest tunnel contains a series of cells, with each cell containing a single egg laid on a nectar/pollen mixture. A. chlorocyanea is believed to be a host of the kleptoparasitic Waroona cuckoo bee. In southern parts of Australia, A. chlorocyanea is active in the warmer months, with activity peaking around January. In the north it can be found year-round, with activity peaks in May and October. This bee will visit the flowers of both native and introduced plants from a wide variety of plant families, and it's a buzz pollinator. Some of the native plants that it has been recorded on most often include; Eremophila sp., Ptilotus sp., Stemodia florulenta, Solanum sp., Dianella sp., Goodenia sp. and Scaevola sp. It has regularly been observed visiting the following garden plants and weeds; English Lavender (Lavandula angustifolia), Duranta erecta and Lantana camara.
