Differential Grassliopper MeJanoplus differentialis Thomas General Appearance This is one of the larger hoppers, aver- aging one and five-eighths inches from front to the tip of the tegmina or wing covers. A very beautifully colored insect when fully matured. The head, thorax, abdomen and first two pairs of legs are amber or rich brown, the sutures being dark. The wing covers are brownish gray—the true wings being transparent. The hind femora are yellow with black cross lines, while the tibiae and tarsi are bright red, the former with black spots near the outer base. The spines and claws are black. The antennae are red- dish with dusky tips. The nymphs are green. Life History Egg-laying begins about the middle of the summer. The holes for the eggs are drilled into the soil in bare and vacant places, especially in alfalfa fields. From 60 to 80 eggs are laid by each fe- male. They are protected from winter rains and freezes by an excretion of the female which makes the capsule contain- ing them waterproof. Thjey begin to hatch in the warmer spring months, ap- pearing early in June and keep up their destructive work until August. The young green hoppers, as they mature, acquire wings and assume a yellowish tint, thus causing the belief that there are two dis- tinct species. The largest brood appears early in the summer, and the greatest amount of damage is done by the first of Fig. 1. The Differential Grass
