Would like to supplement our berlee yield of tipula to see what the size distribution looks like. Spent the evening at the Browerville Nalakstuk. It was clear and cold. 21 June Barrow, Alaska Cleaned the lab, then spent most of the morning hand-sorting the upland 800 samples. They produced a total of 1 tipula! Guess we'll go out of the tipula business. Rigged the doors on some new-design emergence traps and repaired 3 old ones, then loaded up 6 of these and our to tanglefoots site II (So. Beach Rioje). Placed 2 emergence traps in Central Marsh - #5-fsw-%A,% and #6-f-s-%A-%Co. These correspond to tanglefoots II-5 and II-6. Also took 4 800 cores corresponding to each of these. Placed the other 4 emergence traps on the ridge - one in a t-r-sw-3lo situation, one t-r-w-%o, the other 2 at nearly any sites. Had a little trouble making them escape-proof.
