Discussion
- Excluding observations at constant high temperature because this is probably stressfully unnatural
- We here assume that only the final instar allocates to reproduction
- Arrhenius parameters were derived from Gregg 1981 data on development under constant and fluctuating temperatures, to be described in detail in a MS in prep. by M. R. Kearney
