Trichothurgus dubius, m, tool, chile

Note the lovely bee tools this species has, in the shape of expanded tibial spurs.This species nests in standing dead columnar cactus in South America. The genus as a whole lives along the western coast of South America. Interestingly one of the species has been found to nest in horse manure, which brings up the point of where did they nest before horses were introduced into South America. So many mysteries.
