  • The cuticle is moulted about four times during the life cycle. (ref: bumblebee)
  • Some species lay their eggs inside the moulted cuticle, into which males shed sperm. (ref: bumblebee)
  • It appears that egg laying and defecation can only happen during moulting. (ref: bumblebee)


  • weight for Wwi was increade, because much more confidence in the ultimate wet weight
