Males cannibalizing females
We found seven cases in Anisoptera where adult males of Orthetrum sabina (n=6) and Erythemis simplicicollis (n=1) consumed conspecific adult females and four cases in Zygoptera (Ceriagrion cerinorubellum, Ceriagrion auranticum , Ceriagrion melanurum and Ischnura graellsii each with one example) where mature males devouring on females which could be the examples of reversed sexual cannibalism. But, only in case of Ceriagrion auranticum both the predator and prey were sexually mature (Reels, 2014); where in Ceriagrion cerinorubellum, Ceriagrion melanurum and Ischnura graellsii victims were teneral and young. Reversed sexual cannibalism has been observed in some spiders ( Aisenberg et al., 2011; Sentenská & Pekár, 2014) and crustaceans (Dick, 1995). Drivers that induce reversed sexual cannibalism could be extreme mate choice ( Aisenberg et al., 2011), food scarcity (Dick, 1995) and parasitism (Tsai & Dai, 2003).
