73.280 [B&F: 2165] Small Ranunculus (Hecatera dysodea) ([Denis & Schiffermüller], 1775)


A Red Data Book species, on roadside verges, chalk pits, gardens, allotments and rough ground in parts of south-eastern England. Locally common at the end of the 19th Century, the species declined rapidly in the first half of the 20th Century, disappearing from the British Isles completely by 1941. It has subsequently recolonised our island and is becoming increasingly common again: following two in Gravesend, Kent, in 1997, a resident population became established in north-west Kent from 1998 onwards. There were also records in Essex and Suffolk in 1999. The first modern day records in Hampshire were in 2009, with individuals in Southsea, Fleet and Andover; 2010 saw six further sightings, ten in 2011, with similar numbers annually thereafter. The county population has two distinct centres, one in the north-east reflecting dispersion from recently established populations in Surrey, and along the south-east coast. Larvae were found in the Andover area in 2013. Wingspan 32-36 mm. Larva feeds on Prickly Lettuce and Great Lettuce, over-wintering as a pupa.
