Abstract: Plant-insect relations are very diverse and affected by many different factors. When the temperature is low, the number of pollinators is mostly limited. In our study we document Diptera taxa collected on the early flowering, legally protected Pulsatilla grandis Wender. Diptera were collected on the Csatár Hill (near Veszprém) and Vörös Hill (at Balatonalmádi) in the spring of 2019. The average number of Diptera individuals collected per hour were 1.7 and 2.4, respectively. At both sites the frequency of visitations was the highest around midday, then became lower in the afternoon. The majority of the collected insects belonged to hoverflies, and the most abundant species proved to be Brachypalpus valgus. However, the proportion of collected males and females was different at the two sites. The understanding of relations between rare plant species and their pollinators is important from the aspect of ecology and nature conservation as well.
