Chemical mate guarding

In most cockroaches, the male and female disengage and do not interact further after copulation. In some species, however, gift giving and postcopulatory guarding may be chemically mediated. In many blattellids, the male offers a postnuptial gift of uric acid to his mate. In some (e.g., X. hamata) the female is attracted to the male s genital area, the source of urate exudates (Schal and Bell, 1982).
