wood wasp

5889   My name is Allan and I live in the Greater Toronto Area, Ontario.  Size is approx. 15 millimeter’s.   Month – December.
Temp – minus 6 to plus 6.   Found indoors of home, main floor.  I looked at the list of bugs on your site. Not sure if this is a wood wasp.

This is a wood wasp in the family Xiphydriidae in the genus Xiphydria – see  http://tinyurl.com/hbqw5wc for an example. Their larvae bore in dead wood, and are not known to be pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.
