Abstract
The weights and lengths of about a thousand individuals of Steganacarus magnus (Nic.) have been analysed and found to have a bimodal distribution. It is suggested that this can be used as an aid to separating the sexes in this species.Summary: An analysis of the weight distributions of adult Steganacarus magnus (Nic.) showed them to be bimodal. Small individuals, without eggs and pre‐larvae had a mean weight of 159 μg and large individuals with eggs and pre‐larvae had a mean weight of 335 μg. It is suggested that these two weight classes represent male and female individuals.Keywords
