QUEENSLAND, Australia - A rare, supersized wood moth has been found at an Australian school on the edge of a rainforest.

Weighing 30 grams and equipped with wingspans of up to 10 inches, giant female wood moths are some of the biggest moths in the world. Males are half the size.

Females are so heavy that they barely can fly. 

Females usually stay hidden inside eucalyptus trees where they await a male. Larvae are laid in the tree, before emerging around a year later as caterpillars. They then lower themselves to the ground, feeding on the roots of the tree before evolving to their final form.

Females don't eat - they live off of stored fat obtained as larvae. They live only a few days as moths before dying.

This particular female moth was discovered by builders at an ongoing construction site at the school. They took a few pictures before placing it back into the wild.

Teachers at the school made the most of the discovery, inspiring a creative writing session. Some students reportedly wrote of giant moth invasions and teachers being eaten.
