European firebugs (Pyrrhocoris apterus) first appeared in Salt Lake City in approximately 2008. The only documented population of this insect in all of North America is in Utah. Help NHMU track the dispersal of this new arrival.
Here's what you need to know:
1. How to identify a firebug
Firebugs look very similar to boxelder bugs (Boisea trivittata).You will know you've found a firebug if it has a red body with two black dots on its back. Firebugs range in size from 6.5-12 mm (about the same size as a boxelder bug). They have prominent eyes that seem to come from their shoulders. Firebugs, unlike boxelder bugs, cannot fly.
