I've spent a lot of hours sitting by my hive in Bound Brook, central NJ, watching my girls and so I know they are 100% Italian. (Bound Brook was a destination for Italian immigrants, now attracting lots of Spainish) Looking at the clover and other flowers I can always find another bee, It is the size and appearance of mine but is very dark, I want to call it black or gray black. What could this be?
