Eggs, final-instar caterpillars and metamorphosis of cyclosia macularia guérin méneville (lepidoptera: zygaenidae) from its larval host plant baccaurea motleyana

Information on the immature stages of Zyganidae moths is rather limited compared to that on the adults. An encounter with the caterpillars on the Baccaurea motleyana tree enabled a description of the eggs, final-instar caterpillar and characteristic cocoon of the Chalcosiine Day-flying Moth, Cyclosia macularia Guérin-Méneville, accompanied by illustrations. Sexual dimorphism of this species based on the adults is also described.
