  • Austria - near Vienna

Larva: The 22mm final instar larva is yellowish white whose only markings,viewed from top,is a vessel which shows up as the dorsal line. The head is black and the thoracic plate is bone coloured.The larva feed by night and hide during the day in spinnings of leaves.
Pupa: Pupates in a cocoon among leaves
Overwinters as: Ovum
Observations: This moth is easily recognised from the distinct two dark brown fascias which are edged on the inside of the median area with black.
The moth is a local species relying on broadleaved Oak woodlands which is rarer further north and decreasing, and as such is a species of the UK Biodiversity Action plan.
The subspecies found in Great Britain is f.hartwiegi Reisser, 1927 which tends to be lighter with cross lines showing much clearer whereas f.nubilata Robson is much darker brown.

The moth normally flies from dusk and is attracted to sugar and wine ropes as well as being attracted to light where it sometimes appears in reasonable numbers at the moth trap.
