Food Resources
Erythemis collocata is known to feed on the western malaria mosquito, Anopheles freeborni. This predation primarily occurs at dusk, when A. freeborni aggregate into swarms in order to mate. Due to the reliance of E. collocata on visual stimuli to attack its prey, the frequency of attacks decreases as the sky gets darker.
