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.
