No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Ephoron virgo. Interestingly (to me at least), this is the genus of (winged lifestages) mayflies which has either (2) tails or (3) tails, depending on whether male or female.

Do all Polymitarcyidae have 2 or 3 tails? Also which sex has 2 tails and which sex has 3 tails?

Just curious,
Mark

Hi Mark-

The N. American species of family Polymitarcyidae are as follows:

Campsurus cuspidatus
Campsurus decoloratus
Ephoron album
Ephoron leukon
Tortopsis primus
Tortopsis puella
Tortopus circumfluus

It is my belief that only genus where winged males have (2) tails, and winged females have (3) tails is Ephoron, and the other three genera all have only (2) tails, independent of sex.
