One was ovipositing, I have found two eggs on the Bloody Dog leaves: P.S.: Can anybody help me to identify this moth?
Edit: This moth is most probably Brown Oak Tortrix - Archips xylosteana

Edit 19th June 18:56: I just have found another 5 eggs, so totally 7 eggs of Lycaena dispar found in my garden.
Edit 20th June: Another 2 eggs found, totally 9 eggs. I have found also 10th egg but one was detached and fell into the grass.

I have marked the leaves with ova by the thread and the plats by the fillet, resp. fillet on the skewer: http://traplican.rajce.idnes.cz/Ldispar_zahrada#
