## Abstract Forty‐eight cuticular hydrocarbons (CHCs) were characterized by gas chromatography‐mass spectrometry from the epicuticular surface of the major Afrotropical malaria vector __Anopheles gambiae__. The hydrocarbons identified were 14 __n__‐alkanes, 16 monomethyl alkanes, 13 dimethyl alkanes, 5 alkenes, with main‐chain lengths ranging from C~17~ to C~47~, and the results are consistent with those from other Culicidae species. Qualitative differences were not observed between laboratory pools of three females and males, between different age‐groups (0–16 days) and between single field specimens, whereas quantitative differences in CHC profiles were observed. Differences between sexes were more marked in individuals aged 0–2 days than in older ones. Both sexes undergo strong CHC profile changes with age, and individuals aged 0–2 days differ remarkably from the older ones. The possibility of exploiting these changes for estimating the age of mosquito was explored through multivariate analyses of the relative abundance of the compounds, using either the whole CHC profile or a subset of CHCs. Such a method allows us to assign more than 85% of females and 75% of males to the corr
