I found theseinsects also quite common on the edge of the woods, and itwas not an uncommon sight to see them, in the last half ofAugust, scattered in the open fields immediately skirting thewoods. I not infrequently saw the females sunning themselveson old pieces of wood, lying on the ground, while the moreactive males often sought the bark of such trees as the butternut,on which to sun themselves. In these sunbaths, the malesoften associate with the lubberly locust. In their foraging excursions, the males more often than thefemales climb on various shrubs, several feet above the ground,where they feed on the foliage. But both sexes seem to bemore common on the interior bed of the forest that I havedescribed above, than elsewhere. The two figures in the upperpart of the plate are males; the single figure below is the characters of the species are so well shown in these figuresthat a detailed description seems superfluous. ECOLOGY—INTERPRETATION OF ENVIRONMENT 355. Blatchleys Locust (Melanoplus hlatchlcyi). The two vpprr figuresare males, the lower figure is a female. 356 NATURE SKETCHES IN TEMPERATE AMERICA The functionless short wings in Blatchleys locust, as wellas the allied green-legged species, prevent their use in wings have either become diminished in size, or havenever become developed, such as occurs in the long-wing specieslike the Carolina locust. When their habits are taken intoconsideration, one finds that the short-wing species of locustsalmost always live on plants and shrubbery, excepting duringthe time they lay their eggs in the ground. Carrying the argu-ment still further, Morse observes that short-wing species ofacridians generally are much less numerous proportionallyin treeless, arid districts than in humid, forested regions,east a
