Giant Jawed Longhorn
A large prionine with impressive curved mandibles from the tropical forests of South America. While smaller than the famous M. cervicornis, it is still a formidable insect. Males use their enlarged mandibles in combat over females.
Did You Know?
The mandibles of males can account for nearly a third of total body length and are used like antlers in combat.
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.
