Activity is a key behavioral trait that oftenmediates a trade-off between finding food for growth andevading predation. We investigated how activity of thedamselfly Lestes congener is affected by larval state andpredator presence and if larval behavioral type (BT) can beused to predict larval emergence behavior. Activity level ofindividual larvae was studied without predators at twodifferent physiological states (hungry, fed) and in twopredator treatments (familiar or unfamiliar predator cues).Larvae did not adjust their activity depending on state orwhen subjected to unfamiliar predator cues but a generalreduction in activity was seen in the familiar predatortreatment. Hence, active individuals remained activecompared to their conspecifics, independent of state orpredator treatment illustrating the presence of a behavioralsyndrome. However, we found no correlation betweenlarval BT and emergence behavior. Active individuals didnot differ from less active individuals in any emergencecharacteristics. The results illustrate that the larval BToccurs in many situations keeping active larvae active evenin maladaptive situations. Furthermore, we show that damselflyemergence behavior can be completely decoupled fromlarvalBT, indicating a loss of stability in individualBT duringcritical stages in ontogeny.
