The night before arriving in Adelaide, I noticed giant mutant moths on the hostel door — they were as big as two or three of my fingers! Later, our guide, Brenton, brought some inside, along with a tree-frog. The moths are actually incredibly docile.

We later learned they are giant wood moths. They spend most of their lives as caterpillars, becoming a moth for just a couple days before dying. During that time, they only breed and lay eggs, not bothering to feed. This may explain their lassitude, and indifference to predators, cars, rain, etc.

Later, we saw huge numbers of them at a rest stop, counting about thirty in the women’s room. And outside a service station, one crawled up (the outside of) Jason’s pant leg to lay eggs. Nice.
