Horntail?
Hi Bugman,
Very cool site; I must check in at least once a week. I am an avid macrophotographer and came across this insect in Delaware on Nov. 14th. I am quessing it may be a Horntail. The last tergite of the abdomen has a spike that resembles an ovipositor. It was found on a pokeweed in a white pine forest. Its body lenght was about 2.5 cm minus the antenna and spike. I checked my field guides and did a few internet searchs to no avail. Any ID assistance would be appreciated. Thank you,
William Brozy

Hi William,
What a gorgeous photo. We flipped it to maximize its size on our site. This is a Parasitic Wasp in the superfamily Ichneumonidae. We are not sure if it is a true Ichneumon, or a Brachonid. We will see if Eric Eaton can provide an answer. Eric wrote in that in his opinion, this is an Ichneumon.
