Hello, Igor!

I think those must be Agelastica alni (Chrysomelidae, Galerucinae). For comparison:

I haven' got it confirmed. I put the question on a swedish coleoptera forum, but no reply there. There were as you say several larvae on each leaf. The name fits (alnus=alni), but there might be other species that looks similar. There aren't many photos depicting the coleoptera larvae to compare with either. As you see on the other thread I have put a link to the german site with a photo of the Agelastica alni larvae.

J?rgen Peters idea is right. There are three leaf beetle species on Alnus. The legs of the larvae of Chrysomela cuprea and Linaeidea aenea are yellow. No doubt: Agelastica alni - this species is very common and widespread. bg Frank
