List of moths of Australia (Cosmopterigidae) facts for kids
The Cosmopterigidae are a large family of tiny moths. Many of them are very small, often with shiny wings. They are found all over the world, and this article focuses on the species that live in Australia. These moths are part of the bigger group known as the moths of Australia.

What are Cosmopterigidae?
Cosmopterigidae are a group of moths known for being quite small. Many species have metallic or shiny scales on their wings. This makes them look very pretty, almost like tiny jewels. They are often called "cosmet moths" because of their ornate appearance.
Size and Appearance
Most Cosmopterigidae moths are only a few millimeters long. Their wings can be narrow and pointed. They often have patterns of lines, spots, or bands. These patterns are usually made of different colored scales. Some even have raised tufts of scales. This gives them a unique look.
Life Cycle of a Moth
Like all moths, Cosmopterigidae go through a complete life cycle. This includes four main stages:
- Egg: The female moth lays tiny eggs, often on a host plant.
- Larva (Caterpillar): The eggs hatch into larvae, which are caterpillars. These caterpillars are usually the feeding stage. They eat plants and grow bigger.
- Pupa: After growing enough, the caterpillar changes into a pupa. This is a resting stage where the moth transforms.
- Adult Moth: Finally, the adult moth emerges from the pupa. The adult's main job is to reproduce.
What Do They Eat?
The caterpillars of Cosmopterigidae moths are often herbivores. This means they eat plants. Many species are leaf miners. This means they tunnel and feed inside plant leaves. Other caterpillars might feed on seeds, stems, or even galls. The specific plants they eat can vary a lot between different species of moths.
Where Do Australian Cosmopterigidae Live?
These moths are found across many different habitats in Australia. They live in various places, from forests to grasslands. Because their caterpillars often feed on specific plants, their location depends on where their host plants grow. Scientists discover new species in Australia quite often. This shows how rich and diverse Australia's insect life is.
Groups of Australian Cosmopterigidae
The family Cosmopterigidae is divided into smaller groups called subfamilies. Here are two main subfamilies found in Australia:
Chrysopeleiinae
This subfamily includes many species of tiny moths. They are often found in warmer parts of Australia. Some examples of genera (groups of species) in this subfamily are Cholotis, Leptozestis, Orthromicta, and Trachydora.
- Cholotis exodroma (Meyrick, 1897)
- Leptozestis anagrapta (Meyrick, 1897)
- Orthromicta argonota Turner, 1923
- Trachydora actinia Meyrick, 1897
Cosmopteriginae
This is another large subfamily of Cosmopterigidae moths in Australia. It contains many well-known genera. These moths also tend to be small and often have intricate patterns. Some common genera include Cosmopterix, Labdia, Limnaecia, and Macrobathra.
- Cosmopterix attenuatella (Walker, 1864)
- Labdia deliciosella Walker, 1864
- Limnaecia phragmitella Stainton, 1851
- Macrobathra alternatella (Walker, 1864)
- Pyroderces rileyi (Walsingham, 1882)
