Genus: Megachile Latreille, 1802
Subgenus: Amegachile Friese, 1909
Common name: none
Megachile (Amegachile) have black integument, sometimes with some reddish coloration, and a combination of tan, red, white, or black hair on their body (Wu 2005; Michener 2007). They range in body length from 9–20 mm (Wu 2005; Michener 2007).
Some Megachile (Amegachile) can be mistaken for Callomegachile due to similar coloration (Michener 2007). However, female Callomegachile lack cutting edges between the teeth on their mandibles, which are present in Megachile (Amegachile) (Michener 2007). Unlike Megachile (Amegachile), Callomegachile males have lateral marginal hairs on S8, and their abdomen is at least twice as long as wide (Michener 2007).
Megachile (Amegachile) is known to visit flowers from the following plant families: Acanthaceae, Asteraceae, Campanulaceae, Fabaceae, Lamiaceae, Orchidaceae, Papilionaceae, Pedaliaceae, Proteaceae, Scrophulariaceae, and Solanaceae (Karunaratne et al. 2005; Gikungu 2006; Ikudome and Yamane 2007; Welsford and Johnson 2012; Sugiura 2014; Batley 2019).
Megachile (Amegachile) are known to use pieces of cut leaves to construct their nests in pre-existing cavities (Maeta et al. 1997; Sugiura 2014). They have been observed nesting in the old nests of ground-nesting wasps and the abandoned burrows of Stimpson's skink (Plestiodon stimpsonii), a small lizard (Maeta et al. 1997; Maeta et al. 2006; Sugiura 2014).
Megachile (Amegachile) consists of thirty species (Michener 2007); none are known to occur in the U.S. or Canada.
There are no known invasives.
Megachile (Amegachile) occurs in Africa, Asia, and Australia. In Africa, they range throughout sub-Saharan Africa, from Senegal to Ethiopia to South Africa and Madagascar. They are found in East and Southeast Asia, where they range from India to Japan and south through Indonesia to Australia (Michener 2007).
