Notes

A species which is easily recognised by its size and white coxa. The historical data from north-western Europe seems to show it used to be more common in the first half of the 20 th century and earlier. In most countries, it is now confined to coastal dunes near the North Sea and Baltic Sea and / or inland calcareous grasslands where its main host, Arctia caja (L.) ( Lepidoptera , Erebidae ) still occurs. Mostly found under bark.
