OK, then I saw another one between the leave, and to my surprise, they proceeded to have sex... ^^ So, if you ever wonder how they do it... first one of them climb on top on the other then they somehow joined and made the V shape position, see below:
What's next? Well, I left those two to their own after that, so I really don't know what's next, but I read that they can take quite a while... ^^
