Megachile (Megella) may be confused with bees within the subgenera Megachile (Neocressoniella) due to both sharing the characteristics of a strong preoccipital carina behind the gena, an elongate body, and brown to black pubescence (Gonzalez 2008). Megachile (Megella) can be differentiated from Megachile (Neocressoniella) by the shape of the abdomen, which is twice as long as wide in Megachile (Megella) (Gonzalez 2008).
Megachile (Megella) have been observed visiting flowers of plants in the family Lamiaceae (Kakutani et al. 1990).
Megachile (Megella) nest in preexisting cavities and have been observed nesting in wood (Katayama 2004). They have also been observed reusing cavities over several seasons and nesting in aggregations (Piel 1933; Katayama 2004). Megachile (Megella) use pieces of leaves to form brood cells (Gonzalez 2008).
There are no known invasives.
Megachile (Megella) are found in Africa and Southeast Asia (Michener 2007). In Africa, they range from Liberia to the Congo Basin. In Southeast Asia, they are known to occur in India and China (Cockerell and Caldwell 1927; Michener 2007).
