Nest Rove Beetle
A medium-sized rove beetle with pale brownish elytra, specializing in bird and mammal nests. It exploits the rich invertebrate fauna that develops in the warm, organic-rich nest material.
Did You Know?
By preying on flea and fly larvae in bird nests, this beetle provides an indirect benefit to nesting birds by reducing their ectoparasite burden.
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.
