A. aquaticus and A. meridianus have a passive phase in which the male carries the female for some days before moulting and copulation are possible. The effect of varying male: female ratios (0.5:1; 1:1; 1.5:1) is discussed in this paper. It was found that an increase in the proportion of males led to: a) earlier initiation of the passive phase; b) lower gain rates from paired females; c) an increased tendency for males to leave females; d) a reduction in the strength of the association between the timing of pairing and oviposition. The relevance of these observations to models of optimal female guarding and foraging strategies is discussed.
