Cotton Bud Moth
Crocidosema plebejana
At rest this small tortrix moth folds its wings steeply over the body like a roof and sits motionless on stems, dry bracts and dead leaves. In that position its dull, broken pattern passes for a fragment of withered plant.

Introduction to Cotton Bud Moth
At rest this small tortrix moth folds its wings steeply over the body like a roof and sits motionless on stems, dry bracts and dead leaves. In that position its dull, broken pattern passes for a fragment of withered plant.
How to identify a Cotton Bud Moth
- Forewings are mottled in grey and brown
- Wingspan is about 12 to 16 mm
- Hindwings are plain grey-brown and hidden when the moth is settled
- Thread-like antennae lie back along the wings at rest
Why Cotton Bud Moth are interesting
- Australian cotton growers know the caterpillar as the cotton tipworm.
- A cotton plant that loses its growing tip to a caterpillar often responds by branching into several stems.
- On cotton the damage is reported mainly early in the season, while the plants are still young.
- In Australia, outbreaks on cotton have been linked to wet winters, which favour the mallow weeds the moth breeds on before the crop is sown.

Adaptations and biological abilities
03
Why does Cotton Bud Moth behave this way?
- Forewings are mottled in grey and brown
- Wingspan is about 12 to 16 mm
- Hindwings are plain grey-brown and hidden when the moth is settled
- Thread-like antennae lie back along the wings at rest
Adults fly after dark. They spend the day at rest on or near the food plant, while caterpillars feed out of sight at any hour.
04
Why Gardens?
Habitat: Gardens, allotments, cotton fields and disturbed ground where host plants in the mallow family grow; larvae bore into buds, shoot tips and developing seed capsules.
Native range: Domesticated worldwide

05
Why this diet?
Caterpillars tunnel into the shoot tips, flower buds and seed capsules of mallow-family plants, including cotton, hibiscus, tree-mallow and wild mallows, eating the soft tissue inside. What the adult moths feed on is poorly recorded.
06
Activity, rest, and lifespan
Adults fly after dark. They spend the day at rest on or near the food plant, while caterpillars feed out of sight at any hour.
Adults probably live one to two weeks. The cycle from egg to moth is thought to take about a month or a little more in warm weather, and longer in cool seasons.
07
Cotton Bud Moth reproduction
Eggs are laid singly on shoot tips, buds and young capsules. The caterpillar bores in on hatching and, once fully fed, pupates in a silk cocoon in the damaged bud or in litter below. Several generations follow each year in warm climates.
Males and females are similar in size. Forewing pattern is reported to differ between the sexes, but telling them apart takes a close look at the settled moth or a specimen in the hand.
08
Predators, threats, and defense
Parasitic wasps are known to attack tortrix eggs and caterpillars, and spiders, predatory bugs, birds and bats are likely to take caterpillars or moths. The caterpillar is protected mainly by feeding hidden inside a bud or capsule.
09
