Thanks for your question!
The insect pictured is a nymph (juvenile form) of an earwig. In the case of the location that you are reporting from, it is most likely a European earwig (the most common species in Colorado).
Earwigs are a very common insect, and depending on the situation, they are often considered beneficial. They are omnivores, and feed on a variety of things including other insects (such as aphids).
