Knapweed Fritillary

Take a look at the pictures and info in the link: http://www.lepiforum.de/cgi-bin/lepiwiki.pl?Melitaea_Phoebe The black spots on the forewing (margin) are usually not so clearly seen in Phoebe as in Cinxia. In yours there are quite good visible. And still: It is a central and southern European fritillary and should not be so far in the north as your indicated location. And as it happens with a lot of these tricky genus, there is quite a great variability in ground color, markings and hairs.

Hamburg is too far north for Phoebe and Phoebe is the largest European fritillary and yours seems to be a medium size. What about Cinxia? http://en.wikipedia.org/wiki/Glanville_Fritillary

Wonderful spotting! Please, add this one and all your other butterfly and moths shots from Europe into the group: http://www.projectnoah.org/missions/8574613 Would be nice contributions!

Might be Heath fritillary butterfly, but it is very hairy...
