Hadn't noticed many ants on the ground, but yesterday was apparently 'flying ant day' in Bath - the whole place was crawling with themchildren screaming and adults doing a strange twitching dance everywhere they went. Then by the afternoon they had totally disappeared.
I have noticed that they seem to have two "flying ant days" I'm guessing this is a backup in case the first wave is washed out by rain or something, we just had the second one here in London. The only strange dance I do is trying to avoid stepping on the loveable little creatures.
