We measured and evaluated how temperature and predation risk affected growth rates of predaceous
damselfly nymphs (Enallagma vesperum, Odonata: Coenagrionidae).
Using
damselfly nymphs (Lestes congener) hatched in the lab, researchers put nymphs of various sizes in two different temperature environments, one a balmy 18 ° Celsius and the other a toastier 24 ° Celsius.
