Many common insects of the Eastern United States can be found in West Virginia including aquatic insects. The state's beetle number about 15 species. There are more than 70 species of odonate, about 18 species of spiders and a dozen species of stonefly. There are about 17 moth species. Of the wasps, some meadows may have a burrow of yellowjackets. The forest can hold a hive of hornets hanging from a branch. Sweat bee and mosquito are no stranger to the shaded wet-land which delights the sunfish and catfish in nearby deeper pools. West Virginia trout has but one mayfly on which to feed. It is the West Virginia burrowing mayfly (Ephemera triplex) along with the mountain stream's terrestrials and the other insects. The Mountain State's warmer season's flora glitter with about two and a half dozen species of butterfly.West Virginia DNR - Wildlife Resources http://lutra.dnr.state.wv.us/cwcp/appendix2.shtm
