Creepy Crawlies

New Zealand has only one type of land mammal (our native bats), so our insects took the place of small mammals like rats. They grew super-sized. We have the largest weta, the largest carnivorous snail and a giant earthworm that is over a metre long! Meet the giants of the insect world. There are five different types of weta – tree weta, cave weta, giant weta, tusked weta and ground weta. All together there are over 100 different species of weta.
