Description of the Egg and Nymphal Instars of Mαcrolophus pygmαeus Rambur (Hemiptera: Miridae)

Abstract

The egg and the nymphal instars of the predator Macrolophus pygmaeus Rambur (Hemiptera: Miridae) are described and illustrated. The changes of the egg as observed from outside the plant tissue during incubation and the eclosion process are also described. A key for the separation of the nymphal instars is given based on the relative length of the third and fourth antennal segments and the relative length of wing pads. Changes in the colour of the adult, from its emergence until it has obtained its final colour are also described.
