Intruder alert, intruder alert

Back on the 14th when I had seen a potential intruder I didn't have my camera.  So, I went back later in the day and took my camera to see if I could capture anything else.  Low and behold, an intruder.  While standing at the hive I got two shots of this bad boy...who ultimately flew off after not being able to find the entrance to the hive.  I wonder what other devious creatures have been attempting to hijack my babies?
