Do I see a Mayfly or another species? - Megarhyssa macrurus
Santa Fe, Santa Fe County, New Mexico, USA
October 5, 2008
Size: Unknown
Could you help identify this bug? My friend saw it in Santa Fe, New Mexico this weekend.

I believe it's in the mayfly family but, haven't found a specific match on many sites I've checked.

Thanks much!

Jerry

Not mayfly.
This is some kind of ichneumon wasp, family Ichneumonidae. No, that is not a stinger, it is her egg-laying organ, called an "ovipositor." This species probably parasitizes wood-boring beetle larvae.
