The Gatekeeper (Pyronia tithonus) sometimes called the Hedge Brown is a common butterfly in the United Kingdom and Ireland. It is a member of the subfamily Satyrinae in the family Nymphalidae. The name “Gatekeeper” may refer to its frequent occurrence near field gates and to the man who was responsible for the toll gates in the eighteenth and nineteenth centuries when butterflies were more numerous than they are today. As indicated by its alternate name, the gatekeeper butterfly prefers the habitat of meadow margins and hedges; field gates are often in such locations, and thus the Gatekeeper can be found much more frequently in such locations than the Meadow Brown for example.
