Urocerus gigas (giant woodwasp, banded horntail, greater horntail) is a species of sawfly, native to the Palaearctic and North Africa. Adults are usually between 10 and 40mm (0.5 to 1.5 inches) in length.[1]

Larva

Subspecies:

  • U. gigas gigas
  • U. gigas taiganus

U. gigas is a wood boring insect which attacks softwoods of freshly felled logs/unhealthy trees. The species leaves discrete tunnels, frequently filled with hard packed coarse fibrous frass, hard to dig out from tunnels. The tunnels are large, round and discrete between 6-7mm.

Urocerus flavicornis was once considered a subspecies of gigas, but is now a separate species [1].
