  • Its life cycle comprises aquatic stages (egg, four larval instars, and a pupal stage) and an aerial adult stage. (ref: PeryMons2002)
  • Widely distributed in the northern hemisphere at temperate latitudes. Lentic and lotic environments, usually in organically enriched waters (ref: PeryMons2002)
  • larvae, collector–gatherers, feed on sediment-deposited detritus (ref: PeryMons2002)
  • if head capsule width is not taken into account, C. riparius can be considered isomorphic during the larval development. (ref: PeryMons2002)
  • Adult females produce 1 egg mass (ref: SahrRafa2010)


  • we assume that all the data from PeryMons2002 and PeryGarr2006 are in time since birth, and that it the 2-d old individuals at the start of the experiment just hatched
  • males are assumed to differ from females by {p_Am} only
  • I assume time since birth in the time axis of the data
  • the maintenance is high, which is a stark contract to the assumption of 0 maintenance costs by the authors of the data used here: PeryMons2002 PeryGarr2006. The mydata file contains heat production data (as well as the reference) which is not yet implemented. One might consider implementing this to see if such high maintenance is consistent with that additional information.
