Genus: Megachile Latreille, 1802
Subgenus: Litomegachile Mitchell, 1934
Common name: none
Megachile (Litomegachile) are bees with broad abdomens, pale hairs, and white abdominal bands, and female scopa are white except for the last sternite (Michener 2007). These bees range in body length from 8–17 mm (Michener 2007).
Megachile (Litomegachile) may be confused with bees within the subgenera Megachile (Eutricharaea) and Megachile (Megachile) due to their size, pale hairs, and white abdominal bands (Michener 2007). Female Megachile (Litomegachile) lack the white hair bands beneath the scopa found on Megachile (Eutricharaea). Unlike Megachile (Megachile), Megachile (Litomegachile) males have an erect spine on the fore coxa and females have a T6 which appears concave in profile (Michener 2007).
Megachile (Litomegachile) are known to visit flowers in the plant family Fabaceae (Neff and Simpson 1988; Krombein and Norden 1995). They have been observed collecting pollen using thoracic vibration (Neff and Simpson 1988).
Megachile (Litomegachile) are typically ground nesting bees which have been observed building nests in road banks, dry undisturbed fields in hard soil, and underneath rocks, but have also been observed nesting in trap nests (Medler 1965; Eickwort et al. 1981; Williams et al. 1986). Further, they are known to use circular and oval pieces of cut leaves to form nest cells, nest plugs, and the bottom of their brood cells (Medler 1965; Williams et al. 1986; Kim 1992; Krombein and Norden 1995; Katayama 1997).
There are no known invasives.
Megachile (Litomegachile) ranges from British Columbia to Quebec in Canada, throughout the U.S., and south to Oaxaca, Mexico (Michener 2007). Only a few species of Megachile (Litomegachile) are known to occur in Neotropical areas (Michener 2007).
