Don't use messenger bug, use signals (fires, bugs making pyramids, whatever). Especially for simple communication ("the enemy is over here").
As a defensive alarm system, to muster all units at the threatened point in defensive operations, what you suggest is very useful. Not so useful in offensive operations. You also need to find out any enemy force numbers and capabilities and also movement and direction. A loose screen of messager bugs not only as your eyes, but you can have relay of bugs keep an eye on the force that's discovered. Almost as good as RT satellite imaging.
