. 1. Aggregation in the lime aphid is influenced by the newly‐born nymphs staying close to their mother. 2. The aggregations are brought about by gregariousness between the first instar nymphs and their reluctance to move far from their birthplace. 3. As the nymphs mature they become more wide‐ranging and leave the aggregation. Dispersal is also promoted by a lack of gregariousness between different instars. 4. Such aggregations remain intact only as long as the adult continues to reproduce the relatively sedentary first instars. 5. The significance of this behaviour in the spacing of the lime aphid is discussed.
