Lunate Ichneumon
A reddish-brown parasitoid wasp native to North America. It targets horntail larvae in hardwood trees and uses its long ovipositor to reach them.
Did You Know?
It is the smallest of the three North American Megarhyssa species but still impressively large.
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.
