Earwigs are long and narrow, they have the pincers on their abdomens, and most don’t even have wings.
Cockroaches have appendages on the end of their abdomens, but they’re not pincers. They act more as antennae to feel behind them. Cockroaches also have wings the same shape has grasshoppers which means their flying is incredibly inefficient.
Cockroaches are more closely related to mantises and termites.
