Megachile pugnata

Megachile pugnata is a species of North American bee in the family Megachilidae. It was described by Thomas Say in 1837. M. pugnata is a larger species of Megachile, with the typical female’s body length ranging from 12-18 mm and the male’s 11-13 mm. The outer carapace of both the male and female is completely black in color. Females’ eyes are black as well, while the males have lighter colored grey/green eyes. The ventral aspect of females’ abdomens are characterized by rows of densely packed hairs, which facilitate the collection of pollen. Males have much less densely packed rings of hairs between each segment of the abdomen. Both males and females have large mandibles, an important attribute for the females who use them to slice through leaves to create their nests. The females have a pointed end to their abdomen while the male's abdomen has a clublike, rounded terminus. The female's limbs are all covered in hairs while the male's fore-limbs are heavily modified with a dense brush of bright yellow hair.
