Here's a spider I never thought I'd ever find. This adult Trochosa terricola turned up in one of my pitfall traps yesterday. It is male on the right side and female on the left side, split half and half right down the middle!

It has what appears to be half an epigyne, on the female side, while the right palp appears to be that of an adult male. In addition, the left/female chelicera is longer and more robust than the right/male chelicera; and, the right/male legs I and II appear to be longer and darker in some segments than their female counterparts (see the ventral view).

Gynandromorphs are always fun to see, not often that true spiders are seen like this... At least this is the first one I have seen. :)

Ditto, I saw the pics of the Pokie that Phalagorn documented.

That is absolutely amazing!!!! Great find, jsloan! I had heard of these, and I find this quite fascinating.

Thank you for sharing this great find!

I have to admit, that is just about the strangest thing I have ever seen...
