Bearded Bee — By the looks of this character, he's working hard to keep his head warm for this cold, blustery winter! Then again, that's not entirely true since this guy comes to us from Argentina.
He's classified as Mourecotelles, Unknown Hairyeye Bee, found in Argentina. However, that is about all we can say about this species other than it is found in the western temperate regions of South America. It belongs to a little studied group and most of the work that has been done comes from museums where 22 species have been described from various collections. There is one note that a few nests were found in wooden traps nests that mimic naturally occurring beetle holes or cavities in plant stems, whether that holds true for all species is unknown.
Just in this genus alone exists dozens of graduate degrees, waiting for someone to explore this group’s life history.
