Width, to mm. The eggs were laid on their sides. In captivity they were placed in a single row. The color is a delicate ivory-green when first laid, changing later to ivory-white, speckled with small brown dots and dashes, as shown on Figure 1. At first there appears to be a number of faint longitudinal. Figure 1. Egg of Epiplatymetra grotearia. Enlarged X 50. lines on the surface of the egg, barely discernible under X 16 magni- fication. Later these lines become indistinguishable. There is apparently a cap-like micropyle at one end of the egg, but this is faintly indicated in only a few examples, and is absent in the others. The 18 eggs in our original lot all hatched on July 14, 1956. The young larvae were tried on leaves of oak, peach, cherry, pine, rasp- berry and willow. They accepted the willow, and several were carried to maturity on Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Southern California Academy of Sciences.
