Hi Donna & All,
Many insects make holes <=3D 1 mm.
Did that larva come from the same wood and is some of the damaged =
wood softwood ? Lyctinae, according to the usual story, feed only on =
hardwood. Normally hardwood would not be used for posts.
If her post wood is still around then chunks in an improvized =
Berleise (sp?) funnel or formaldehyde in a bag, applied to one end, =
might yield some specimens. Perhaps you have tried this. An adult =
specimen would reduce the guessing game from impossible to difficult.

Subject: [NatureNS] strange wood boring insect destroying a NS home
A colleague who lives in Caledonia, brought in some skeletonised wood =
from her home last week. We could not find any wood boring insects in =
the pieces she brought in, but I thought I would submit this mystery to =
the masses. The holes are very tiny (see photos), quite unlike those of =
carpenter ants, and the sawdust is exceedingly fine. Most alarmingly, =
she has had to replace the wooden support posts in her basement (now =
made of steel), and tells me that this same beast is now chewing its way =
through her hardwood floors upstairs. She is guessing that it is in =
other supporting structures of her home. Ykes. =20
=20
Anyone have any ideas? Photos taken as best I could. I suspect her =
home will require some sort of treatment. =20
