Can you tell me what kind of bug this is?
August 10, 2009
Just got back from a camping trip in Teller County Colorado and this bug landed on my leg. I have searched high and low on the web for pics of this insect.
Please help, Thanks Jon and Family
Dear Jon and Family,
This is a Giant Wood Wasp, Urocerus gigas. It is also called the Greater Horntail Wasp or the Yellow Horned Horntail. According to BugGuide: “Range Introduced, originally from Europe and Asia. Habitat Attacks five or more genera of Pinaceae Remarks It tunnels in wood. One of the most dangerous pests of conifers.“ We will be tagging your post as an Invasive Exotic.

Not an invasive exotic wood wasp
I was certain that U. gigas the exotic form has yet to be established here in the US. Upon discussion with our entomologist he is positive it is Urocerus gigas flavicornis (Fabricius) which is a native subspecies. Colorado is just one of the states that it can be found. You had me worried there for a minute. Our cups runith over with exotics as it is like Sirex noctillio. Great work as always and glad to see you folks have links to get in touch with the proper agencies that handle exotic invasive pests. I encourage your readers to become aware of exotic invasive pests, report new finds and help protect our resources.
Can’t wait to see your book
