A marking method was developed and used for studying spider mite behavior. Nest ownership (longer male residence in a nest) had little influence on the consequence of male-male combat. Furthermore, age differences in males never affected the outcome of the combats. Length of male leg I, however, appeared to be an important factor. Factors affecting variation in male leg size were examined. Length of leg I was strongly affected by host plant quality but not by male age.
