Tachystola acroxantha is a moth native to Australia and now widespread in New Zealand. It is an adventive species and was probably imported with Australian plants. It has a preference for Eucalyptus species (Myrtaaceae).
The adult is an easily recognisable moth with three black spots on its brown wings. The outer edge of its fore wing has a yellow/orange margin. Its has a wingspan of 13–18 mm and a forewing length of 7-9 mm.
The caterpillar lives in a shelter constructed by joining leaves loosely with silk and on withered leaves and leaf-litter. For pupation, it constructs a more substantial shelter between leaves using stronger silk and also frass.
The adults can appear during summer when they are attracted to light.
