Hurd 1952 August 6. warm - light jacket not worn. The mosquitos in considerable abundance even about AR - so much more so out on the marshes. Copious quantities of 6/2 needed to keep them off - but still hovered about in large clouds making it necessary to periodically clean the air about yourself when working in limited area. Cigarette smoke has a very strong, repellent action on them. Both species of Bombus present + collecting pollen from the staminate patches of Petasites (which incidentally are at margins of the more marshy areas and leaves (wet) from the high ridge. Both workers & queens of B. sylvestris present - no males. Of B. moderatus only queens. One queen of the latter was observed in high dry ridge cutting off bits of willow leaves (some of which are red) and carrying (?) in mouth the masticalid (?) portions If. No nests located to date. A new moth to the area was captured flying near high ridge (?) and one other noted. Many Syphids of 3 spp about the staminate flowers of Petasites, apparently after nectar - also a ♂ Bot fly (O. tarandi) was observed in the same flowers; 1 other presumably a ♀ buzzed me. Muscid activity evident
