What unusual paternal responsibility do male Belostomatidae insects undertake during reproduction?

The male carries egg masses glued to his back until hatching.

The reproductive cycle of the Belostomatidae family showcases highly unusual parental care, with the burden of protection falling predominantly on the male. After mating, the female secures masses of eggs directly onto the dorsal surface (back) of the male. The male then assumes the critical role of carrying these eggs until they fully develop and hatch. During this extended period of paternal responsibility, the male often refrains from eating or seeking appropriate shelter to ensure the security and survival of the developing brood against predators and environmental hazards.
