T. subafricollis
above (W) of Upper Meadow Lake-
I collected:
Group of 3 flying around O and

collected: #345 - Imm.

13 August
Group of 4 on Beach Ridge, ca.
150 yds. S. of CAS. 1 seen feeding
onlichen polygon slope - others on
dry ridge top. I collected: #347-
Imm.
Group of 5 - O end of P's Plot-
dry slope (14A35). I collected:
#346 - Imm.
2 birds - S. slope P's Plot, ca.
stake 6.
1 bird - (15A45) - E. side
of Wohlslag Slough, ca. 100 yds.
N. of road.
All birds were actively feeding
in dry tundra. Why the sudden
appearance and burst of feeding on
previously abandoned ground. Could
be new crop of adult appearance
insects. Does not seem likely that

birds to exploit it. Something else stoke
