(Lancaut Nature Reserve, Gloucestershire, July 2011)
I was very excited to find this moth as it looked fairly exotic but it turned out to be extremely common all over Europe down to Iran and up to Scandinavia... the only exception being Portugal. So I may be excused for never having seen one before. It's a day flying moth and there is another species with only five spots.
Its scientific name is Zygaena filipendulae.
