description Frosted Orange Moth Overview
The Frosted Orange Moth is the Palearctic noctuid Gortyna flavago, a species described in the eighteenth century. Adults have orange to orange-brown forewings with lighter, frosted-looking markings that help distinguish the moth from plainer noctuids. The larvae live inside and bore through the stems of host plants, where they remain concealed while developing. This stem-boring life cycle links the species to herbaceous vegetation in parts of Europe and neighboring regions.
help Frosted Orange Moth FAQ
What is the scientific name of the Frosted Orange Moth?
Its scientific name is Gortyna flavago, a noctuid moth in the family Noctuidae. The species was described by Denis and Schiffermüller in 1775, not in the nineteenth century.
Where do Frosted Orange Moth caterpillars live?
The larvae bore into the stems of plants such as thistles and burdocks and feed internally. They can also pupate inside the stem, which makes the caterpillar much less visible than the adult moth. [UKMoths larval information](https://www.ukmoths.org.uk/species/gortyna-flavago/larva/)
When are adult Frosted Orange Moths active?
In Britain, adults are commonly recorded from August to October in habitats such as woodland edges, waste ground, and marshes. Their orange to orange-brown forewings with frosted markings help separate them from plainer noctuid moths. [UKMoths species account](https://www.ukmoths.org.uk/species/gortyna-flavago/)
Does the Frosted Orange Moth visit flowers at night?
It is more strongly associated with flying to light than with visiting flowers for nectar. The larval stage is the most distinctive part of its biology because the caterpillar develops inside the stems of herbaceous host plants.
