Everyone forgets that ants make silk (as do bees who also make wax... the show offs) ants don't just use silk to protect their eggs and pupae like many arthropods. Some ants use silk in nest construction. Which puts them in the company of spiders. The way that ants use silk also requires TWO or more ants to pull it off. Several weaver ants hold leaves close together. Then another ant picks up her baby larvae sister and taps her to tell her to make silk. She then cements the leaves together.
