Mayflies have two Penises


“Aquatic entomologists place little emphasis on body color when attempting to identify a mayfly species. They collect virgin, male, mayfly spinners, and dissect them to clearly see their penes (mayflies have two). They then count the spines on the penes and compare them to photos in books to identify each species. There is no way to be sure of the species from a female spinner, and you may not be able to tell from a nonvirgin male. No kidding! I couldn’t make this stuff up.”
see ? as seemingly far-fetched, mind-boggling, thought-provoking and mostly giggly because it’s not like these two thingies are going to double their pleasure..,  as much as i like to make up shit i didn’t make up this post’s title either.

seeing how some aquatic bugs breathe through their butts and then all the others do all sorts of other weird things, that one little fact (ok, two) doesn’t help us all that much if we’re trying to match a hatch on the stream but it’s all good to know because well, knowing is better than not knowing, it’s cool and this kind of stuff is just a reminder that fiction usually isn’t so far-fetched after all. the weird and mostly wonderful is all around us and it’s real.

sometimes it’s a little confusing. can you name these bugs ?

Paul Weamer’s excellent article, Understanding Mayflies on Fly Fisherman -via Erin Block’s super-duper Tippet section at MidCurrent- doesn’t give us all the answers either but goes a long way in getting to know our little friends a little better.

click either pick to access the complete article and please excuse the fact that the main character in the second image isn’t a mayfly but hey, it might turn into one if you stare at it long enough… enjoy !
