The Colorado potato beetle is generally found on potatoes, tomatoes, eggplant and other solanaceous family plants. Adults become active in May and lay eggs on the underneath side of leaves. Damage to crops when populations are high, especially in the 2 week time frame of potato flowering, can be significant. If you have a few plants, the best thing to do is scout them closely and handpick any eggs or insects.
