Thelatter is, perhaps, a little more sprightly on the wing andconsiderably smaller than his neighbor above referred to. In general, the pasture is drier than the meadow, due to adifference in drainage. Here the prevailing plant species aregrasses, or the ground is invaded with perennial herbage, suchas I have described in the beginning of this article, in whichcase we have a blending of pasture and meadow. The lifeI have portrayed above is that living under both pasture andmeadow conditions. In another chapter I have described indetail the Pasture Locust, which exemplifies a typical pastureinsect living under conditions of restricted plant association. GENERAL OBSERVATIONS AND SKETCHES AHELD 293 The Undeb-leaf Inhabitants ,jA». E have seen thesmall mothsflying out quite—— conspicuouslyfrom among theundergrowth as we trodalong through the shadywoods. But though quite inevidence for the moment, theysoon disappear as suddenly asthey came. Most of these in-sects readily conceal themselvesHere is one I have just followedto its retreat. Turning the leaf gently over, I find the snow-white form a perfect type of aesthetic beauty. As a rule, Iobserve that the whiter their color the more seclusive theyare in their habits, resorting to the underside of the leaves,generally in the darkest part of the woods. Those havingtheir wings normally spread apart or open are often scallopedat the margins, which is typical of the geometrid habits of concealment are of the utmost importance inprotecting them from the birds which readil
