Birch tree insect - Tremex columba - Female
Winnipeg, Manitoba, Canada
August 14, 2011
Size: 1.5 inches
This insect sticks a needle-like tool into the birch tree. It almost looks like it does this to anchor itself in order to shed its abdomen skin. It leaves the needle and skin behind. You can't really see it in the photo but its abdomen is striped black and yellow kind of like a wasp's.

That's it!
Thank-you for responding so fast!

That's definitely it. Based on the reading I did, it looks it's laying eggs in the tree. It must be that these are showing up now that the tree is dying. This is the first year we've ever seen them and there's been a few already.

Thanks again!
