Horntails, Wood Wasps and SawfliesSome type of ichneumon wasp?
Hi,
I took these pictures of two what I think are ichneumon wasps laying eggs in a dead elm recently affected by Dutch Elm disease. Both wasps took about 5 minutes to drill about an inch into the wood. The larger wasp pulled out after 15 minutes and walked around with the antenna feeling along the bark. The smaller female unfortunately was stuck and died. Here are some photos of these wasps. Any additional info would be most interesting. Great site!

Hi Claude,
This is a female Pigeon Horntail ovipositing. She is a true Wood Wasp and the larvae bore in wood. Interestingly, this is the prey of the Ichneumon that you mistook it for.
