CONCLUSION
We provided evidence for cannibalism in odonates based on our observations and literature review. Our results are indicative of higher proportion of female driven cannibalism compared to intrasexual cannibalism and reversed sexual cannibalism. In Anisoptera, cannibalism occurs between two mature individuals, and between mature and immature individuals. Whereas in Zygoptera mature individuals chiefly acted as cannibal and mostly tenerals become prey. We recommend testing the different mechanisms of cannibalism in adult odonates through experimental studies. Future studies should focus on an experimental approach to determine the ecological and evolutionary driver of cannibalism in odonates.
