Summary The spatial distribution of the eggs, larvae, pupae and adults of the wheat‐bulb fly was investigated by fitting 42 sets of data comprising 1334 samples to the Poisson and negative binomial distributions, and by using the power law ( S 2 =am b ). In general, the tests indicated that all stages were aggregated and fitted the negative binomial model.
