I popped the telescoping cover off of the Ambrosium today to see whether I could peer through the crown cover's hole and see whether there was any drawn comb on the upper super (the superior?) I couldn't see a thing because the there so many bees there. So I closed up and walked away. I didn't pry off the crown cover since I wasn't geared up, had no smoker, and had no hive tool. As I walked away an ambrosiana got me on the hand. It made a big dark bruise.
