Horntail or wood wasp are any of the 150 non-social species of the hymenopteran family Siricidae, a type of wood-eating sawfly. The common name "horntail" derives from the stout, spine-like structure at the end of the adult's abdomen which is present in both sexes.

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.

The Greater Horntail Wasp is actually an insect which is completely harmless, but when this one turned up in a Market Warsop pet shop in August 2012, no doubt some panick ensued. We were called in to collect it and identified it as Urocerus gigas. Its UK distribution is patchy and they are largely found in coniferous areas.
