Small Ranunculus Hecatera disodea
This species became extinct in the UK in the early 20th century but has now re-established and is increasing. In Norfolk it is most common around urban areas and as I don't generally trap in such places I'm yet to encounter one of my own. This one was trapped by David Norgate who gets them regularly in his Toftwood garden.
