July 7 Sampling Notes fulls for their young - many of which are rapidly reaching the stage of leaving the nest. Other midges of small size were swarming but not so conspicuous or in such abundant numbers as the large midge. Surface of many tundra pools especially even around ARL were in their shore edges covered with the cast pupal skins of these large midges. Some pools apparently have not had the midges started emerging while others have had a great number come off - at least judging by the pupal skins. Exploratory work continued on the ridge and at willow ridge area - a marked increase in number of surface insects took place in spite of the short duration of sheltering away to the overcast. Average meter count in willow growth gave 15 chneumuids; 10 sawflies; 8 diptera - mostly Ephydrids; 5 spiders - count made in 15 minute intervals. In Lelasisites type of meta plots got average of 15 diptera - mostly Ephydrids; 10 spiders; and 1 chneumuid a sawfly - count 15 minute intervals; in Mardla area 10 spiders; ±50 midges in flight across plot during count of 15 minutes. at Pedicularis sito
