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

Do all Polymitarcyidae have 2 or 3 tails? Also which sex has 2 tails and which sex has 3 tails? Just curious, Mark

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.
