Pisaurina mira

Moved from Spiders. Nice one, but I'm not sure it's a male.

I've unticked the male selection because
you surely know more about these things than I do.

If it helps decide, it was grayish and very roughly, 6-7mm. (The
ruler was all kattywumpus against it so the size is more a
guesstimate due to the bad angle.) They looked like two very
different spiders in color, size, the striking pattern of this
one, and the barely discernible pattern in the other. The
female was closer to the size of a well-fed N. crucifera in length.

P, mira
Actually your other spider looks more like what the males look like. The females can have quite a variety of colors. Take a look at the info page to see what I mean.

leg length
Thank you, yes, the info page brought home to me the variety of these spiders. :o) I spent some time looking at the other pictures and developed a theory about leg length. It seems to me these spiders are consistently ID'd male if the leg is at least twice as long as the total body length. The opposite seems to be true for females (less than twice). I'm awfully curious to know if you think this theory holds water.

leg length
That's not just a theory, it's a fact. The adult males of this species have much longer legs. This is true in many spider species, but not all.

leg length
That's terrific to know. Considering the hours it took me to figure that out,
it was time well spent as I'm much more likely to remember it because of that.
Thank you! :o)
