Value of species
An Adriatico-Mediterranean stenophagous species preferring steppes, forest steppes and meadows in open woodland as well as the ruderal biotopes reaching up to 600 m. Single eggs are deposited usually on the upper side of the leaf, only exceptionally on the underside. The larva bores a wide mine in the terminal part of the leaflet and pupates in the mine under the thin, dead leaf epidermis. Larval development is very short, only 24 days. The first generation of beetles emerges in May – June, the second generation (if developed) in June – July. Adult beetles hibernate in the detritus around the host plants and they start activity with the first warm, sunny days in April of the next year. Host plants: Fragaria vesca, F. viridis, Potentilla neumanniana, P. anserina, P. recta, P. reptans (Bílý, 2002).
