Fucking carpenter bees (aka winged termites). Ironically, the males have no stingers but they are extremely aggressive and will kamakazi dive bomb you in the face repeatedly if you get near the entrance to the nest.

Yeah fuck those guys. Had an awning built over our patio and didn’t even get through the whole summer before one started digging a hole into one of the rafters. Our backyard is now a no-fly zone for those bastards.
