Discussion

  • For now, this entry focuses only on females
  • It is assumed that the start of energetic investment in the reproduction takes place during the imago stage (synovigeny) because (a) imagos still feed on live prey, and (b) the wet weight of total reproductive output exceeds the adult female wet weight by a lot (making reproductive investment only during the larval phase implausible)
  • mod_1: Pupation is triggered by reserve density at emergence equals reserve density at pupation
  • Whenever studies reported the pre-pupa duration, here it was added to the pupa phase due to functional similarity (neither feeding nor growth take place)
  • Not all developmental studies reported the pre-pupa duration, meaning that it was either included in the larval or the pupal duration; however since the pre-pupa phase was always very short, the resulting uncertainty is considered tolerable
  • mod_1: the kappa-rule applies to all stages

Facts

  • Development of ovaries takes place after emergence in the female imago (Ref: PhooObry1995)
  • Imagos continue feeding on aphids (Ref: JalaReit2019)
