Summary A model is presented for analysis of mark‐recapture data of mobile insects which, unlike the Lincoln Index, does not require marked individuals to remain within the sampling area or to mix uniformly with the wild population. The model assumes a single or multiple releases of marked insects from the centre of the sampling area and that captured individuals are not returned to the population. Dispersal rates of marked insects are estimable from serial recaptures and, for catches that are either unaffected by or have been corrected for weather effects, the model also provides estimates of mortality and age‐dependent trappability. Application of the model is illustrated using mark‐recapture data for adults of the Australian sheep blowfly Lucilia cuprina .
