I've heard of these, they sound amazing!

We get the odd Hercules moth in our backyard. Doesn't look anything like a bird close up, but it's so massive that when they get stuck in the house your first thought is that it's a bird or bat.

Another cool thing we get is jumping spiders that imitate ants so they can hunt them - both green ants (an endemic weaver ant we get here) and another large metallic silver ant species I don't know a lot about. The spiders share the colouring of each species and walk backwards amongst them - their walking style changes and the abdomen looks like the head of the ant. They're rare, I've only observed them a couple of times over the years here, but it's wild to watch them do their thing.
