so I went for a walk with my family in South Darenth KENT and we saw thousands of bees at about 9pm

they were light brown almost cream HUGE and they kept flying at us trying to sting us.

every tree was surrounded with them and we don't think they are English

they were completely out of thir minds flying round us constantly and we had to keep in the middle to stay away from them.

there was no hives but they were everywhere and very protective.

we then realised several of them kept falling to the ground unable to fly.

when they stopped flying they had no stripes were just light brown.

IS THIS NORMAL AND WHAT ARE THEY?
