Discussion
- Life span (and h_a) relates to imago
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, what_when_how)
