This is a bee that is appearing in the gardens right now. It's called a Xylokope bee. This is the biggest bee in Europe (2.5 cm). She doesn't sting (unless we chase her, of course). Xylocop is the so-called "lonely" bee. But it can live in colonies, i.e. side by side. Black with blue wings.. she is very beautiful but can be scary, her flight is fast and very loud but not aggressive and rarely stings. It is for protection because it is rare and very useful. Some people mistake her for an Asian hornet!!!
