August which are apparently the chief pollinators of this plant. Other Muscidae flies of apparently same species (fumatidinae species) were also visiting flowers of Potentilla and Senecio. There were a large number of ichneumonids were about the petasites, and a molly in the small size some apparently hyperparasits. 1 orange species (Aedes) resembles the one I reared earlier in the season from a larva of Chrysomela subcuculata. No longer noted in immediate area but some were heard further up the ridge towards ARL - at Wilimovsley Pass - also taken at that spot were some specimens on crop analysis sheet. Around ARL there were flying in tremendous numbers late this afternoon, evening before the rain came. Many midges; many were scared up by the weasel. August 2: overcast with rain good part of day but was fairly warm as midges were flying behind ARL in the rain - spent day on the banding grid. Small groups of Baird +1 Semipalmated Sandpipers gathering about pools in banding grid & probing for insect larva (presumably chironomids). August 3: Fog-mist-rain most of day with very high NW wind spent day on banding grid.
