My daughter told me, it could be a Zyganae ephialtes, which is a European burning moth. Very unpalatable to birds. Nevertheless I had to search for a while. There are some very similar looking moths out there. Now I'm quite sure it's a mating pair of nine-spotted moth, which is also called yellow belted burnet – a Amata phegea. They have only white dots, a yellow belt and the antennae have white tips. The wingspan is somewhere between 35 and 40 mm (1.4–1.6 in).
Victoria wasn't completely wrong, she was cheated by mimicry. The nine-spotted moth imitates its appearance with the same warning coloration as the burning moth. Maybe it's also unpalatable to birds, I don't know and the birds don't know either.
The smaller male moth is on the left side of this mating pair, on the right side is the bigger female moth. The female will lay the eggs on low plants like dandelion, grasses, sorrel, fleaworts and other low plants.
The family Erebida is in English called tiger moths, in German they are called "Bärenspinner". The German name is more fitting, because the fat brown furry caterpillars look like bears.
And again I ask myself: "Why is never enough light to photograph something special and interesting properly?"
