It hardly seems to be ground breaking research to realise that the Brown Argus has apparently stopped using Rock Rose in places where it is a rare plant.

And to go back 100 years or so, wasn't the Comma traditionally associated with hop, especially cultivated hop fields in Herefordshire (and to a lesser extent Kent)? Then it began preferring what until then had been a secondary foodplant, nettle. And look at how the comma has spread in the past 100 years?
