We describe the first record of amphisexual care in an insect with uniparental male care. Male Rhynocoris tristis are noted for aggressively guarding multiple egg masses. When a male is unable or unwilling to guard eggs, a female that has previously contributed eggs returns to the egg mass and defends it until the eggs hatch. We compared the frequency and intensity of parental aggression in both sexes and found no difference in either form of guarding behavior. Evidence of amphisexual care in R. tristis provides an opportunity to quantify the cost of care in both sexes within a single species. © Japan Ethological Society and Springer-Verlag 2006.
