Hymenoptera Anthophila Megachilidae Megachile representative


Megachile (Sayapis)
likely inimica sayi (note dark wings)

Yes, it can
A female of the genus Megachile, belonging to the group of the "true" leaf cutters. That is, they really deserve their name by putting pieces of leaves to crosswall the cavities - most often inside wooden structures - they use as nest for their brood.
The shape of the gaster, above all the concave foreside of the first segment, is peculiar to this genus.
