Females have a small tubercle instead of a horn. Larvae feed on roots of ash trees. Immature stages look like very large white grubs and can be found in compost heaps or occasionally infest potting media. Larvae take most of the year to develop and spend the winter. Adult beetles are active in the summer.
Mouthparts are for chewing.
Larvae live in rotten logs or high organic matter conditions. Adults do not seem to feed much but may eat leaves. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
