Many of the butterflies of July continue to fly during the whole or part of this month, and several fresh species commence their flight. August, too, may be looked upon as _the_ month for second broods, and an opportunity now arises for searching for some of the species that were missed at the time of their early appearance in May. Clover and lucerne fields should be well worked. A few _Sphinges_ and a number of the _Bombyces_ are still on the wing. The _Noctuae_ are on the decrease, but there are yet nearly a hundred species (including the rarer ones) at large. These last may be taken at sugar in considerable numbers, and it is interesting to note that two of the Vanessas (_Atalanta_ and _Cardui_) may be caught sipping on your baited trees during the daytime. _Geometrae_ and Micros fall off very considerably this month, but these, as well as moths of the other groups, may be taken from tree trunks and palings. Light traps may also be used with much success during August. Fallen fruits should be examined for the larvae that feed within them; and late in the month ripe fruit will supply food to the lovers of sweets. Ivy blossom should be well worked at night; and clover and lucerne fields form admirable hunting grounds for moths at night, especially just after rain. Larvae are to be obtained in abundance by beating and searching, the latter process being conducted by night as well as by day.
