The diel and seasonal drift of Chironomidae exuviae was assessed for one year in a non-regulated stretch of a Mediterranean river in south-east Spain. Pupal exuviae of chironomids were collected by drift netting, and 43 species were identified. Maximum densities were captured in summer and minimum densities in winter. Orthocladiinae were the most widely represented group with 19 species being identified in high densities. Overall, the time preferred by the chironomid community for emergence changed with the seasons, although the principal species maintained their daily cycles of emergence.
