Organ Pipe Mud Dauber
A slender black wasp that builds distinctive parallel tubes of mud resembling organ pipes under eaves and overhangs. Males guard the nest while females hunt.
Did You Know?
Males are unusually dedicated fathers for wasps, standing guard at the nest entrance against parasites while the female hunts.
Yellow-Legged Horntail
A large, dark-bodied wood wasp with bright yellow legs that contrast sharply with its blue-black body. Found primarily in conifer forests of eastern Asia.
Did You Know?
Like all horntails, the short horn-like projection at the tail is not a stinger but a structural feature called a cornus, present in both sexes.
