Beetles in Delaware

Delaware doesn’t have too many recorded beetle species in the state, and of the fewer present, the emerald ash borer beetle is one of the infamous pests, mainly infesting ash trees. The southern pine beetle is next on the list, also harming pine trees. The carpet beetle species, on the other hand, are harmful indoor pests.

The ladybug is Delaware’s Official State bug, with the Asian lady beetle being one of the most prominent beetles of this family found here.
