Rattle Ants (Polyrhachis sp.) are big black and shiny tree ants. They look like your best pair of highly polished patent leather shoes. Only ant shaped and a lot smaller and not really shoe-like at all and a bit more shiny. They build messy nests made up of mushed up bark and leaves and silk. The nests hang in trees looking untidy and although I’ve never heard it, the ants may shake the nest and make it rattle to ward off intruders. The really clever bit is how they make the nest using their own larvae as silk dispensers, drawing leaves together in a clump and holding the larvae in their mandibles extruding silk so they can stitch it all up.
