This one will grow big, conspicuous and with clear transverse stripes on the abdomen :P It is something very popular

Well, Simeon, I like quizzes.

Young specimen of Pisaura sp.?

If it isn´t Pisaura, then I have a completely different idea. Much larger.

Definitely not Pisaura.

You can find it in two threads not long ago.

Well, it actually looks like the male.
I think I would have gotten there in 3 or 4 days. I was focused on other families.  :(
Thanks Katja and Simeon.  ;)
Do I reveal the name or do we continue the quiz for other forum users?
It could be instructive.

I think that is the problem we all have had when we saw it for the first time.

In hindsight, it's easy.
I should have paid more attention to the posture assumed by the spider in the first photo, and to the habitus that seems to be that of the male of this species.
But I was deceived by the "vertical" taken by the spider in the second photo, which I saw in Erigoninae and Pisauridae.
Now I give a very unscientific clue, which I learned from a post by Ulrich Kursawe: it is the favorite spider of the fans of Borussia Dortmund.

Around here they are the largest spiders, as far as I know (the females). My kids always insisted to call them Tiger Spider.  8)
