Key words: Coleoptera,
Heteroptera, pollen, pollinator, protected plant species, shelter.
The pollinators of Adonis vernalis L. flowers were studied in the
spring of 2017 and 2018 at two sites (Szentkirályszabadja and Csatár hill)
in Veszprém county, Hungary. In this paper, observations of non-Aculeata
species are reported only, as data for Aculeata flower visitors were
published earlier. Altogether 68 insects were collected during our study.
Tropinota hirta was the most abundant species, representing 43% of
all flower visitations. Coleoptera was the most abundant order (58%),
followed by Heteroptera (22%) and Diptera (19%). Mating of Heteroptera
species (Pyrrhocoris apterus and Lygaeus equestris) and
sleeping Coleoptera species (Coccinella septempunctata) have been
observed in the flowers as well, that confirms the combined functions of
flowers. The role of fly species in pollination is definitely small as they
were always found on petals (and not on the reproductive organs of the
flowers). From the representatives of the Diptera order, Bombylius major
touched the flowers only for seconds, so it has probably no role in the
pollination of the species. Adonis vernalis shows incomplete
protogyny (self- and cross-pollination occurs as well), therefore most of
the encountered flower visiting species can take part in the pollination as
they can carry the pollen of the same plant to the stigma while moving in
the flower. Accordingly, the presence of pollinators is necessary for the
reproductive success of A. vernalis. The study of pollinator
species is important from a nature conservation aspect. The development and
implementation of proper conservation strategies help to increase species
and habitat diversity for pollinators.
