A very efficient killer at work, although both are insects. It is no different from a lion eating up a zebra or a deer after successfully capturing it. The big fish eat the small fish - intestines and all!!![]()

This is the reason why humans should be vegetarian.
One theory for the evolution of the group is that mantises evolved from proto-cockroaches, diverging from their common ancestors by the Cretaceous period, possibly from species like Raphidiomimula burmitica, a predatory cockroach with mantis-like forelegs. Possibly the earliest known modern mantis is Regiata scutra, although more common (and confirmed) is Santanmantis, a stilt-legged genus, also from the Cretaceous. Like their close termite cousins, though, mantises did not become common and diverse until the early Tertiary period.
Cockroaches are disgusting.....not sure what role they play in eco system....I think they are totally useless and can do without with no impact
