Mantidfly

thank you very much for letting me know, i had no idea

Hi Ismael, this very cool insect is actually not a Mantis at all! It is called a Mantidfly, Family Mantispidae.

I am not sure which species are found in your area so you still need a bit more research.

Your second image looks like a spider nest perhaps. I don't think it is related to your Mantidfly.
