Hi, I found this bug in my very own backyard, it was sitting on a tree, and appeared to be pumping the tree with… something with it’s 3 inch sting, and I really have no idea what it could be.

Giant Ichneumon Oviposits

Hi Gannon,
We are guessing that you did not recently take this photograph of a female Giant Ichneumon,
Megarhyssa atrata, in the act of ovipositing recently, but rather, you are trying to identify an insect you witnessed during the summer.  Though she is laying eggs, this Giant Ichneumon will not harm the tree.  Her brood will feed on the wood boring larvae of the Pigeon Horntail, an insect that is found in dead and dying wood as well as the wood of trees that are already in decline.
