Pt. Barrow, Alaska Sampling notes July 3 of shore area - additional specimens under the pebbles - probably 3 to 10 per sq. m. An exploratory excursion out to ridge west of ridge plot area in afternoon showed a remarkably increase of midges in wing especially the large pectinate antennated males (see collection). Many Tenthredinidae on high polygons covered with Willow growth, with 5 per sq. meter. Old lemming burrows with rotting vegetative matte, near entrances yielded 10-20 Typhid adults per burrow opening. A few, 1 or less per sq. meter, Fungivoridae (=Myzotopelidae) were observed. Occasionally a specimen Scopaeuma vulpenium was flushed and it flew skyward at 10 to 30 feet height. Others were observed flying near head. First Queen bumble bee captured and additional ones noted, but not captured. In an area approximately 1 sq. acre 10 queens were noted - some in old lemming burrows - in 2 1/2 hrs of observation. 2 mm Noctuid (q.l.) pupal cases picked up on high polygons and were brought in for rearing. Some specimens apparently were feeding on Tenthredinid adults, and some were probably taking Anthomyiid
