. The daily rhythm of eclosion of male Pseudaulacaspis pentagona is entrained by the interaction of the prevailing light and temperature cycles. The onset of light is the critical cue for the release of eclosion. Darkness or increasing temperature inhibits it. A decrease in temperature induces eclosion during the photophase, but does not do so during the scotophase. The eclosion rhythm is modified daily by the prevailing temperature cycle, apparently to ensure maximum survival of, and mating by the short‐lived males.
