Beetle - Mexican Bean
Mexican Bean Beetle
Given its size and spots, you might mistake this pest for a ladybug. Though related to ladybugs, Mexican bean beetles are far from beneficial. Their distinctive bronze background color gives away their identity. Mexican bean beetles are fairly common in the United States, but are most prominent in the southeast and rarest in the northwest. Gardeners east of the Rockies are most familiar with this pest.
