In particular, mantises mostly rely on their amazing sense of sight to locate prey. Unlike most other insects, praying mantises have 5 forward-facing eyes.
The types of food that praying mantises eat in the wild varies depending on the habitat where they live.
Generally speaking, mantises prefer to eat live prey. As such, live insects are going to make up the bulk of a pet mantis’s diet.
