Photographed on the wall of the USACE HQ at Granger Lake, TX. There was a small hatch-out of this species in the area; not massive numbers but numerous at some porchlights in the area. This is a relatively large mayfly. Compare with BG at: http://bugguide.net/node/view/253434

Elizabeth and I had a GREAT time at Tishomingo National Wildlife Refuge -- there must have been some bad flooding a while back, so it looks like visitation has been low... Anyways, we're going back sometime!
