Urocerus gigas is a wood-boring insect that attacks softwoods of freshly felled logs/unhealthy trees. The species lives in discrete tunnels, frequently filled with hard-packed coarse fibrous frass, hard to dig out from tunnels. The tunnels are large, round and discrete, between 6 and 7 mm (1⁄4 and 9⁄32 in) in diameter.

Urocerus flavicornis was once considered a subspecies of gigas but is now known to be a separate species.[2]
