Larval growth rate has the same temperature coefficient in three species of coenagrionids, but Argia vivida and Amphiagrion abbreviatum, which frequently live in geothermally heated water, grow fastest at 29.0–30.0°C compared with 23.4°C for Coenagrion resolutum, which lives in cooler water. Survival below 15°C in the laboratory was much better in C. resolutum. These characteristics…
