Austramathes squaliolus facts for kids

The Austramathes squaliolus is a type of moth that belongs to the Noctuidae family. It was first officially described by a scientist named Robert J. B. Hoare in 2017. This moth is special because it is found only in New Zealand. This means it is endemic to that country.

What Does This Moth Look Like?

Larvae (Caterpillars)

The young moths, called larvae or caterpillars, are known for their bright colors. They have patterns similar to another moth species, A. fortis. You can spot them by their yellow markings on the sides of their bodies. These yellow spots stand out against a darker, marbled pattern on their backs. The marbled pattern on Austramathes squaliolus larvae is darker than the one found on A. fortis larvae.

Adult Moths

When the larvae grow into adult moths, their wingspan is usually between 25 and 31 millimeters wide. This is about the length of a small paperclip. Like the larvae, the adult Austramathes squaliolus moths look very much like A. fortis. However, scientists can tell the two species apart by looking closely at certain body parts of the male moths. These specific features are different enough to show they are separate species.

Where Does This Moth Live?

This moth is found only in the Chatham Islands, which are part of New Zealand. It is quite common there. Scientists have found Austramathes squaliolus on several islands in the group, including Chatham Island itself, Pitt Island, Little Mangere Island, and Rangatira Island.

What Do They Eat?

The larvae of the Austramathes squaliolus moth feed on a specific plant. This plant is called Melicytus chathamicus. It is known as the "host plant" because it provides food and a home for the moth larvae as they grow.

When Do They Fly?

Adult Austramathes squaliolus moths are usually seen flying during the months of November and December. This is when they are active and can be spotted in their natural habitat.
