South Dakota has fewer recorded beetle species, of which the ladybird beetles are present in large numbers. Their presence could be a menace to homes, yet they don’t seem to be harmful. The mountain pine beetle is one of the most infamous pests of the state, mainly infesting parts of Pennington County. Another pest is the pine engraver beetle known for attacking and damaging pine trees. The state even has a decent amount of blister beetles mostly inhabiting the alfalfa fields.
