Colobura dirceNiklas Wahlberg
Colobura dirce has two subspecies, the widespread Central and South American C. dirce dirce and the Caribbean C. dirce wolcotti. The biology of the species is quite quite well-known. Eggs are laid in small clusters of 2-10 eggs on saplings of the host plant Cecropia. The larvae go through five instars, and late instar larvae are velvet black with pale yellow scoli (branched spines). Pupation happens on the host plant, and the pupae resemble dead twigs. Adults are common in a variety of forest and secondary growth habitats from sea level to 1600 m.
Colobura dirce is best distinguished from C. annulata from the immature stages. Colobura dirce eggs tend to be darker, larvae lack the yellow rings that encircle the body in C. annulata, larvae are less gregarious and tend to be found on saplings and seedlings of the host plant. Adults tend to be smaller than C. annulata, with the main distinguishing character being the third submarginal line on the underside of the forewing, which always tapers toward the costa (unlike in C. annulata).
