Is this an Ichneumonid wasp? These insects are quite wary and I am almost never able to get close to them to take photos.

Other Ichneumons
Yes, there are other Ichneumons around but so far I've not been able to get photos of some of the larger ones. Someday...

At that size,
it seems this must be a male Megarhyssa. Any females around? Check in the guide here, specifically something like and where Patrick points out we may not be able to identify the males to species without a female present.

Yes.
Just confirming this image is a male Megarhyssa. Nice work!
