Number 6637. This is a pigeon tremex, Tremex columba (Hymenoptera: Siricidae). Also known as a horntail, their larvae tunnel in the wood of dead/dying hardwood trees where they are preyed upon by the larvae of giant ichneumon wasps in the genus Megarhyssa. Click here for more detailed information.
Thank you for identifying the insect. The pigeon tremex looks much like a large wasp but with long legs, which altogether, looks very imposing. But I am glad of know that this insect is harmless.
