Facts

  • Imagos are extremely short lived and do not feed; nyphs allocate to reproduction buffer and have mature eggs (ref: Sold1979)
  • Estimates of the number of instars in ephemeropterans vary between 10 and 50; most are in the range 15-25 (ref: Brit1982)
  • Final emphemeropteran larval stage transforms into a flying sub-image, which moulds into an imago (ref: Brit1982)
  • eggs have a dormant period; length grows by a fixed fraction over moulting (so Dyar rule is applicable); eggs can develop parthenogenetically (ref: Hump1981)

Discussion

  • Puberty is assumed to coincide with end of acceleration
