Is the dagger moth caterpillar an invasive species?

Asked September 9, 2014, 1:12 PM EDT

I saw one Tuesday, Sept 9, 2014 in North Ogden, Utah. When I looked it up, the information said they were east of the Rockies. Is this a problem, like invasive species? I took a picture.

They are fairly common at this time of year in northern Utah. Maybe the information you saw is not updated, but it has been found in Utah for several years now. It does not seem to be a significant pest.

Thank you for the update, though!
