White-letter Hairstreak garden tick

The White-letter Hairstreak (Satyrium w-album) is a butterfly not very easy to see here in Västmanland. With the Elm decease it seems to have disappeared (since Elm is the host plant for the species) from previously known areas. Although they do re-appear and sometimes in unexpected places. Last year I had one on my backyard downtown Västerås, now one specimen suddenly sat in front of me on a Jasmine-bush in my garden in Fläckebo. A first for the garden! Since there are no Elm trees nearby I wonder if they can adapt to other host plants?
