Though the precise timing does depend on the weather, over the last 10 years the dates on which I see my first Gatekeepers (Pyronia tithonus) rarely vary by more than a few days, around the end of June and the start of July. This year my first sighting was on 28 June, and it was at the same location as in several of the past years, fluttering around vegetation by a gate in to one of the fields at Cosmeston Lakes Country Park. If only all creatures were so predictable – though that would be much less of a challenge!
