Distribution

This species can be found in the Palearctic ecozone.[1] It has a widespread distribution in Britain.[2][3]

Habitat

These moths inhabit open, grassy areas, waste ground, meadows and spruce forest edge.[2][4]

Description

The wingspan is 22–28 mm.[4] They have pale brown or grayish wings with chestnut coloured markings towards the tips.[2] This species is very similar to Platyptilia nemoralis, but it shows a very small scaletooth at the dorsum of the third lobe.[5]

The caterpillars are about six millimeters long at the end of March. They have a glossy black head and black mouthparts, prothoracal shield and thoracic legs. The body is yellow, with a broad reddish back.[3]

Biology
Mines of a larva in a leaf

The moths fly from May to October depending on the location and are active at dusk and night. This species has two generation a year, in June and in late July–September.[2][5]

The larvae feed on coltsfoot (Tussilago farfara) and sometimes also butterbur (Petasites species).[5] The larvae of the spring generation feed in the stem from the base up to the receptacle of the flower head, with pupation taking place either there or on a leaf. The summer generation are miners. The mine consists of a small, transparent, irregularly shaped full depth mine and there are often several in a single leaf. The frass is granular but there is little to be seen, or it is missing completely. After some time the larvae feeds freely on the underside of the leaf or under a folded leaf margin.[6]
