Abstract1 The timing of adult eclosion in forest zone blackflies of the Bandama cytotype of the Simulium damnosum complex in the Ivory Coast was investigated both in the field and laboratory. 2 An eclosion trap and a simple technique for keeping black‐fly pupae in the laboratory are described. 3 Hourly collections of newly emerged S.damnosum adults showed that there was an eclosion peak at 05.30–06.30 hours in the field and at 07.00–08.00 hours in the laboratory. Approximately 30% of the blackflies in the field emerged at 06.00–06.30 hours. 4 S.damnosum kept under natural light‐dark conditions in the laboratory did not show any delay in the timing of the eclosion peak, relative to that of the first day in the laboratory, until the third day of the experiment.
