Chemical analysis of cuticular hydrocarbon profiles of pupae and adults of the ant Cardiocondyla obscurior. One-day old adults of C. obscurior ants were clearly separated by discriminant analysis from the pupae. Ready-to-eclose dark pupae showed a more similar chemical profile to adults than still unpigmented white pupae several days before eclosion.
