While outside yesterday, I noticed a very large wasp sitting on the edge of the 4 wheel dump cart (the first pic taken by my pohone, the second by my camera which I had to go get)
Turns out that is a Giant Ichneumon Wasp. This particular one is a female and her body was about 2" long with the ovipositor a little longer. I never found a statement on Google that anyone had ever been stung - although supposedly they are capable if they feel threatened. This one was very docile as I got in close to get a good picture using the micro function of my camera. The reason I even noticed the wasp was because I was moving the cart back and forth, using it as a step stool (good thing I wasn't at work OSHA would have had a heart attack). The wasp never even moved or even seemed agitated. She may have been newly pupated and drying her wings (even though she moved them a bit, they never seemed to fully unfold, so may have still been damp).
The adults don't eat but the female lays an egg in the burrow of a wood wasp larva and the Gian Ichneumon larva uses that as its meal all winter long. There are several large, old and decaying tree stumps about 15 feet from where I found her, so maybe that will be her final destination. That mean looking ovipositor is used to drill into the wood for the egg laying and they listen for specific sounds the wood wasp larva makes in order to find the perfect place to drill. It is incredible to think that they can determine the type of larva in the tree just by listening! After the GI larva pupates, the adult emerges between June and September.
Although not rare, they live in woody areas from Canada down to Mexico, I don't remember seeing one before, so I'm guessing they aren't "common", as one usually thinks of the word.
Interesting little critter. Don't believe I've ever seen one.
