The insect in your photo is an assassin bug called corsair. It is in the Family Reduviidae and genus Rasahus. According to the Missouri Conservationist they can deliver a painful bite.
Like most assassin bugs they are beneficial insects as they feed on pest insects. The beak that bit you will suck the juices out of pest caterpillars and other insect pests.
One way to reduce contact and bites is to use yellow bulbs in porch lights and do not use bug zappers. To avoid the self-defense bite, gently brush away the corsair or any bug that lands on you, being careful not to smash it on your skin.
