readyrok, I doubt these are flying ants, well certainly not the flying ants I know. In the four years I have been in England, I have not seen a flying ant .
Flying ants range from about half and inch to an inch in length. They.come out of holes in the ground in swarms, at the beginning of a rainy season (that's all year round in England!). They usually fly around lit lights and loose their wings soon after leaving their holes.
The bodies of the flying ant are very tasty and have much goodness in them. I find that they taste like peanut butter!!
