Graellsia isabellae

It's always interesting to see how larvae of the most diverse species come up with similar camouflage patterns when feeding on the same host plants. The camouflage of the Spanish Moon Moth, Graellsia isabellae, is typical for a pine feeder. The caterpillars grow to a size of seven to eight centimeter. The cocoons are spun at the base of the food plant (in captivity at the bottom of the cage). Young caterpillars are best kept in not too large plastic containers, older ones prefer a good air circulation and are better housed in very large plastic tubs or in netted cages. This species is best reared at moderate temperatures. Avoid sudden peaks in temperature, the more stable the breeding conditions, the better. Cooler nights are beneficial. The cocoons will now overwinter and require cool conditions to hatch in Spring. Keep the cocoons in the fridge or make sure they go through a cool period (0° - 5°C) for at least a couple of weeks.
