What's That Bug? does not endorse extermination

What the hell is this thing??
September 23, 2009
My uncle asked me to help him identify this insect. Picture taken today, Sept 23, 2009, in Hopkins MN. The tail end of this bug can fold out & fan out like a chinese fan and it looks like a left–bright green. The long probiscus’ off the back end of it were into the tree, not sure if it was eating something or putting eggs in or what.

Hi Anne,
This is a Giant Ichneumon in the genus Megarhyssa.  She is depositing eggs under the bark and the larvae will feed on wood boring larvae.
