It feeds on the foliage of potatoes and other solanaceous crops. It is extractable from the stems and leaves of solanaceous species. Tobacco has the highest solanesol content amongst all solanaceous plants. Hence, solanesol plays important roles in the interactions of solanaceous plants with environmental factors. Though almost all other Solanaceous crops have toxins in their leaves, chili peppers do not. The false potato beetle feeds on solanaceous weeds such as horsenettle, "Solanum carolinense". However, the larvae prefer solanaceous plants, such as tobacco and tomato plants. It is known from many solanaceous weeds, including "Datura stramonium", "Lycium chilense", and "Solanum nigrum".
