Studies of the Byron Bog in Southwestern Ontario: IX. Insects Trapped as Adults Emerging from Redmond's Pond

Abstract

In the description of the Byron Bog (Judd, 1957a) it was pointed out that Redmond's Pond is situated in the northwest corner of the bog and that during 1956 a tent-trap was anchored in a small bay in the northeast corner of the pond to trap insects emerging as adults from the water. The position of the trap on the pond is shown in the map accompanying the description of the bog (Judd, 1957a) and the structure and use of the trap are also described by Judd (1957b). The trap was placed on the water on May 15, 1956 and remained there until November 8. It was about four feet from the edge of the pond in water about two feet deep. At this point the bottom of the pond was composed of a thick layer of loose, brown peat and the adjacent edge of the pond was occupied by a dense growth of leatherleaf, Chamaedaphne calyculata, growing in Sphagnum (Judd, 1957a). The branches of the bushes of leatherleaf extended out over the water of the small bay in which the trap floated. The only rooted plant growing in and around the trap was spatterdock, Nuphar advena. Floating in the water was a sparse growth of bladderwort, Utricularia vulgaris, and on the surface of the water there were a few scattered fronds of duckweed, Lemna minor, and water flax-seed, Spirodela polyrhiza.

“…Adult emergence in the Dundas Marsh, Ontario, ranged from 595 -9,456 m 2 yr ~ (calculated from data in Judd 1953). Emergence from a bog pool in southern Ontario ranged from 1,397 -19,020 m z yr 1 (calculated from data in Judd 1958). However, only 840 -3,121 m 2 yr -1 adults emerged from shallow Lake Veittij~wi in northern Sweden (Wiederholm et at.…”
