About The Cover

The eggs of the grasshopper, Romalea micropetera, are yellow when first laid, but through the action of a secretion added to them at oviposition, they subsequiently tan to a dark brown. The three eggs were disseccted form the ovary of a gravid female. The eggs on either end have undergone localized tanning as a result of being sppotted and streaked with secreation; the center egg is an untreated control (Actual size, 7 mm). See page 95.
