Ecology

Totally 167 larval groups were located, all on Melampyrum spp. (Fig. 1). In some cases, at least two original larval groups had probably merged. All larval groups were either in clear-cuts (usually close to the edges, and sometimes within the forest 0-5 m from the clear-cut [Figs 2, 4]), in thinned and light commercial forests (Figs 3, 4), or in open powerline corridors (Fig. 5).

Due to the dry conditions in July and August, many or even all host plants had withered especially in open rocky areas. Therefore, reliable identifications based on plant morphology were possible for 121 samples. Of the identified samples, 30 plants (25%) were M. pratense and 91 plants (75%) M. sylvaticum . In addition, three larval groups have been found in the same area in the autumn of 2013, all on M. sylvaticum (Jari-Pekka Kaitila, personal observations).
