A gigantic moth that's too big to fly and rarely seen by humans has been turned up at a school building site in Australia, several outlets report.

Found in wooded areas of Australia and New Zealand, the giant wood moth (Endoxyla cinereus) is the world's largest moth species. Females are twice the size of males, weighing up to 30 grams and boasting a wingspan up to 25 centimetres.

They're rarely seen by humans because adult giant wood moths cannot feed and only live for a few days, reaching their full size just before mating and dying soon after, the Australian Museum says. During the reproduction process, females lay about 20,000 small eggs.

The recently-discovered female was found at Mount Cotton State School in Queensland, Australia, which is located near the edge of a rainforest. After snapping a few pics, crews put her back in the wild.

Unfortunately, the school was closed at the time of the discovery, so students didn't get to see her up close.
