Slender Baskettail Epitheca costalis

See the Common Baskettail. But a basket in Arkansas with wings this clear is likely a Slender. I believe this species is actually more common than the Common, but who knows? There is a rare basket that is very hard to separate from this species. Likely can only be told in hand presently. It is the Robust Baskettail Epitheca spinosa. Named for a spine found on the male cerci. Slender and Commons can swarm together. Both species occur in spring only. Note the slight narrowing of the abdomen up towards the hind wing base on this species. Common does not have this. There are possibly more species of Baskettails in Arkansas. Will have to get back to you on this. (See Mantled.)

And compare also with this male of the Slender (formerly Stripe-winged) from Oklahoma. Note the significant indentation and the more splayed male terminus. I think these are as common in AR. But no one bothered to make sure. Rarely would the Common have this little wing marking but I would not judge species from wings alone. I believe all three of our species above can be separated by quality photos.
