Bees, Spiders and Bugs

I can't recall the name of this but apparently its deadly! I spotted this on the field behind my home

Not quite clear but bees in flight at Castle Bolton. The hive is inside the building and connects with a large glass tube

This and the next two are Water Boatmen. The patterns on the water made by their feet can be seen and the shadows on the bottom

So small, those are bits of dust beneath it.
