- Title
Life stage dependent predator–prey reversal between a frog (Litoriaaurea) and a dragonfly (Anaxpapuensis).

- Abstract
These observations add a unique example of predator-prey reversal that is dependent on life stage and shifts from dragonfly larva eating tadpoles in the aquatic environment to frogs eating dragonflies in the terrestrial environment (Figure 2). First, the green and golden bell frog often selects predator-free ephemeral wetlands to avoid heavy tadpole mortality by predators such as dragonfly larvae (Beranek, Sanders, et al., [6]).

To address these knowledge gaps, we recommend a follow-up study where frogs undergo gastric lavage during periods of high dragonfly metamorph emergence (October and November) and compare this to periods of low dragonfly metamorph emergence (February and March).
