Great friend, quite a coincidence that you found this specimen of the Uloboridae family. Really, in the case of this species, it does look like a dry leaf. On the other hand, I was very surprised to see this spider, if my memory serves me correctly, I think this family is cosmopolitan, and therefore, they are on different continents of our planet; I do not remember well, but I think it is so. Very nice pictures, greetings!
