The Stingbee is an ammo type for Stranger's crossbow. Flying around they look like 

regular, real life wasps, these bugs are used like a machine gun. They fire fast, home in on targets 

but only cause light damage. So enjoy these critters sparingly! They come in 30 shot clips, but can be upgraded to 50 shots.They later become upgraded to Super Stingbee's which fire faster and deal more damage. Stranger first encounters them either on his way to rescue Eugene Ius or just before encountering Jo' Ma Ma depending on the order the bounties are taken in.
