MaeLee 1969 Journal (22Jul) In the afternoon - tanglefoot change (nearly done!) and emergence trap check (1♀ Pedicia!). So this has really been a low crane-fly year - all species together, i.e. almost certainly weather-induced. Put up another Black Guillermod after dinner, then caught up on field notes. 23 July Barrow, Alaska More cold West wind; I have never seen so much west wind in a summer. Tanglefoots and extra sleep in the morning. Emergence traps in the afternoon - 1 lonely ♀ Pedicia. I marked ♀ Tipula are more than one week old - that shatters one of my old ideas. The long life span buffers weather induced variation in insect emergence. Safriel seems to think that the burn weather has resulted in adverse feeding conditions for his pusilla, but Norton has seen no evidence for this in alpina or bairdii. It is certain now that the weather does not greatly produce the periods of emergence, as I thought it might. This means we must enter another element into the control of emergence mechanism.
