My new nuc this year swarmed June 15th, Fathers Day. Saw them 20 ft up in a tree behind the hive on a branch big as my arm. Tried to get them in a nuc box while hanging on to a ladder. Didn't work but was quite impressive seeing them go over the garage, through the front yard and to parts unknown. No stings and I'll chalk it up as a learning experience.
Hot 80 degrees, muggy mostly clear, 30 miles south of Indianapolis
