Extract
In the description of the Byron Bog (Judd, 1957c) it was pointed out that one method of collecting insects in the bog was to make a circular sweep with an insect net, held at arm's length, through the tops of the bushes in the Chamaedaphnetum calyculatae association. The net used was one with a rim twelve inches in diameter and the radius of the circle over which the sweep was made was six feet. A single sweep was made each day from Itlay 15 to November 15 in 1956 and all the insects collected each day were sorted and counted. The dav of maximum blooming of Chamaedaphne calyculata was May 21 and the day of last blooming was June 1 (Judd, 1958a). Thus there was a period of nineteen days, from May 15 to June 1, when the plants were in bloom while the sweeping was in progress.
