The larvae of one of these, the raspberry geometer {SyncJilora glan- carid), feeds on the fruit and foliage of the raspberry, cover- ing itself with bits of vegetable matter, thus masking itself beneath what is apparently a little heap of rubbish. The owlet-moths {Noctuidae) are by far the largest family of the order, including some twent}'-one hundred species, " three times as many as there are North American species of birds," and form the great bulk of the moths commonly taken by collectors. As their name indicates, they fiy by night (as do all other moths, for that matter) and are frequently attracted to lights, being the common " millers " of popular parlance. They are not readily distinguished from nearly 199 Fig. 3 moth and egg winged male of Adult female mass and the fall cankenvorm.
