The appearance of an article “Window flight traps for insects” by Chapman and Kinghorn (Can. Ent. 87 (1): 46-47. 1955) suggests that it may be well to describe another flight trap. Specimens taken by it have been labelled “caught in cheesecloth trap”, a statement which is true but perhaps enigmatic.

While on the late Ralph Hopping's staff, the writer built a number of cages for rearing forest insects in southern British Columbia. These cages were all 6 × 6 × 6 ft., each on a cloth covered wooden platform, with a minimum super-structure of 2 × 2 in. lumber to the inside of which cheesecloth was tacked to form an insect-tight enclosure. One entered by a door on the lower part of the north or east side.
