About the Giant Wood Moth

Endoxyla cinereus, also commonly known as the giant wood moth, is a species of moth that belongs to the family Cossidae. It is a widespread species being endemic to eastern, southern and southwestern Australia including Queensland and New South Wales and New Zealand. This species is one of the world's heaviest insects, weighing up to 30 grams and having a wingspan of 23 centimeters.

The species was first described in 1890 by J. G. O. Tepper, a Prussian botanist and entomologist. A rare contemporary sighting of the moth at a school in Australia garnered notice as an editor's pick among the daily headlines of the New York Times on May 8, 2021.

It is the heaviest moth in the world, weighing up to 30 g. Its wingspan is approximately 23 cm, or just over nine inches. Their larvae are around 1.5 mm long when newly hatched, but can grow to be as long as 150 mm. Newly hatched larvae are banded by purple and white stripes, with an orange and black pattern on their prothoracic plate and head.

GBIF citizen-science records

It is estimated from how often the Giant Wood Moth is recorded against all the insects logged in Brisbane (24 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
