Dissemination
Platyptilia gonodactyla is widely used in Europe. The species is absent only in the southernmost regions. To the east, the distribution area of Russia and Asia Minor goes to India.
Biology
The moths fly from May to October in two generations. The food plants of the caterpillars are coltsfoot ( Tussilago farfara ) and various Pestwurzarten ( Petasites ). These thrive in moist places in forests, on fallow land, ponds and along roadsides. The caterpillars eat first spring generation on the leaves and overwinter in the rootstock. In the following spring they burrow in the flowering shoot upwards and finally eat in the lower part of the flower. The caterpillars then pupate either in the flower or on the underside of a leaf. The caterpillars of the summer generation living initially as leaf miners and feed on the underside of leaves, where they pupate later.
