When a level begins, scout for food and parts before the action really starts. Leave one bug to defend your stash while the others scout. Set up outposts if you have the opportunity. They will generate coins, take some defensive load from your main turrets, and allow you to range farther when scouting. Eat the food you are defending to restore hit points as needed. Complete missions to earn diamonds and use them to purchase scrolls to improve your bug hero.
