Golden egg bug (Phyllomorpha laciniata Vill) females oviposit on the bodies of conspecifics of both sexes. Studies on the golden egg bug have opened a new approach to understanding how forces arising from sexual conflict act in breeding systems (Kaitala, 1998Go, 1999Go; Kaitala and Miettinen, 1997Go; Hardling and Kaitala, in pressGo), in particular, how females are able to exploit males' sexual interests by dumping eggs on courting or mating individuals. These studies also show that social interactions among individuals may be complicated by sexual conflicts of interest. Many aspects of the peculiar behavior of the golden egg bug are already known, although much of it is still unexplained and theoretically poorly understood.

Here we comment on the paper by Reguera and Gomendio (1999Go) to clarify what really makes the golden egg bug so interesting and unique. The golden egg bug is not unique among . . . [Full Text of this Article]
