Hurd 1952 July 1 Sampling Notes number (+4) typhulid pupal cases. In areas when there is any water, standing, large clouds of midges may be observed unless the wind is blowing quite strongly. July 10 Rained most of the day - no field work. July 11 Meter plots on ridge - afternoon. Clear with a few scattered clouds almost uninterrupted sunnyline all afternoon, slight wind and relatively warmer. Most obvious change in the insect fauna since last visit was the great upswing in the numbers of midges and muscid flies. Large swarms of midges hovered here and then over much of the study area and as the afternoon wore on the individual swarm size increased. Many rested on vegetation, especially around pond margin, or on the exposed bottom (sphagnum) of dried up pools. Others were encountered in almost any moist (when you can't sneel without getting wet) places. A range wriggled base Muscid was out in fairly large numbers + hovered in the air in "mating flights"? near transverse ditch across ridge. Others of this same species were found on the ground and some sitting on flowers of Petasites. In certain moist areas - especially those occasioned by depressions of beaver tracks were Syphidae (Helicophila) buzzin
