Abstract

A 50-month continuous observation of the pollinator fauna of a 30 ha phrygana plot near Athens revealed an alpha diversity of 666 species which is the highest polinator diversity recorded so far. Of these, 262 species were Apoidea, of which only three (Apidae) species were eusocial. In comparison with the pollinator fauna of comparable ecosystems in Chile and California, phrygana has a relatively high number of Bombyliidae and especially Syrphidae. Only approximately 20% of the pollinator species occurred in all years of the research period. The very diverse, and shifting pollinator fauna is hypothesized to have brought the evolution of floral characters to a standstill. A peculiarity of the phryganic ecosystem is a preponderance of pollen as a floral reward and a relative scarcity of nectar. This may be an important factor in the high bee diversity that characterizes the phrygana, and mediterranean ecosystems in general
