Could you please highlight what you see that registers as a somewhat hooked hind wing extension? Even with you typing it out and explaining, I fail to see it.Insecta - Body covered by exoskeleton, three pairs of jointed legs, three body parts, head, thorax, abdomen, generally with two pairs of wings.
Ephemeroptera - Aquatic insects that go through two body stages, a nymph that is wholly aquatic, and a winged adult that has two adult stages, subimago and imago.
Baetidae - Mayflies with a generally smaller body, small to nonexistent hind wings.
Anafroptilum - Also called hookwings because hind wings have an extension that is somewhat hooked.
conturbatum - Went to Anafroptilum on Bugguide and found this;
