Okay, one day we found a drone on the ground, going in circles. Normally Drones get out of the hive in fall, not late spring. We saw it had a brown circle on it's head, one of it's eyes was gone. We kinda took care of it and in a few days it died (possibly of starvation, Drones can't feed themselves). What is it? My brother theorises it may be a worm, but no known worm infests bees. Help, Please!
