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.
CAVE WETA
There are 60 species of Cave Weta
- They are mostly found in caves, which is a good place to hide from predators like rats,
but they can also be found in other dark places such as under houses and logs.
- Cave weta have big back legs and can jump up to two metres!
- The cave weta has very long antennae and legs. It uses it’s antennae to feel around in the dark.
- The cave weta can live up to seven years.
GROUND WETA
There are 36 species of Ground Weta
- The Ground weta cannot hear you coming because it does not have ears on its front legs, like other weta.
- It is the smallest weta and lives in tunnels in the ground.
- Like the Tusked weta, the Ground weta is mainly carnivorous.
- The Ground weta looks a lot like the Tree weta but is smaller.
- It does not have spiky back legs like the Tree weta.
GIANT WETA
There are 11 species of Giant Weta
- The Giant weta is a docile creature and does not kick or bite. To ward off predators (like you and me) it raises its spiky back legs.
- The gentle giant of the insect world, the Giant weta prefers a vegetarian diet.
- The Giant weta often lives under rocks and bush floor debris.
- The giant weta is soooo heavy that it cannot jump.
- Giant weta are endangered and are protected by the Department of Conservation.
TREE WETA
There are 6 species of Tree Weta
- The tree weta is sometimes known as the bush weta.
- The tree weta is the most common type of weta and usually makes its home in the holes of trees.
- The male tree weta is quite aggressive and it will fight another male weta.
- It hisses and bites when threatened.
- The tree weta has a varied diet and will eat both plants and other insects (this means that it is omnivorous).
- The male weta tends to be quite a hit with the ladies. One male often lives with up to ten females.
