Hemiandrus pallitarsis is a common ground burrowing weta about 28 mm in body length. It is native to the North Island and is found at all altitudes up to 200 masl. They are nocturnal and at night emerge to hunt or scavenge invertebrate prey, they also eat fruit. Being nocturnal they are an important food source for kiwi.
Hemiandrus pallitarsis have thread-like antennae which can reach several times the body length. Like all ground wetas, it does not have ears on their forelegs like those of the tree weta. The adults have a lifespan of over a year. The females inject their eggs into plant material in the ground.
