Description
Based upon the necessity for a biocoenotic approach to wild bee studies, the relative abundance of andrenid bees in Sapporo was surveyed by periodical sampling on flowers, in two areas and for two years. Among the 20 species captured (1,709 individuals), Andrena hebes and A. esoensis are regarded as stable dominant species common to the two areas. Andrena benefica, A. watasei, A. sublevigats and A. valeriana are also dominant, but either only in one area or only for one year. Interesting differences in the composition of the andrenid assemblage between the two areas, located near one another, and between 1959 and 1965,are described and discussed. The phenology shows a definite succession, divided into the spring phase with numerous species visiting various flowers and the rather monotonous summer phase with two oligotrophic species, A. esoensis and A. valeriana as dominants. The specific difference in flower preference was given together with the difference between the two areas. Most specimens were captured from a limited number of flower species, among which the introduced species, European dandelion, rape and willows (partly) and native species, Gagea Lutea, Petasites japonicus and willows (partly), are important for spring species, while legumes, especially white clover, are the predominantly visited flowers in summer.
