History
Lennon (1860) stated he had found this species around Dumfries whilst out walking that season. By 1863, Lennon had found it at Caerlaverock, but stated it was not common. Buchanan White (1895) also listed it for Colvend parish. Gordon (1919) found it scarce at Corsemalzie (VC74), but not uncommon at the coasts around Garheugh, Monreith and Balcarry, among whins and sloes. Earliest date was 26th June 1905.
 
Rothamsted data has it recorded at six of the seven stations during 1974-92, Caerlaverock being the odd one out. There are a handful of inland sightings during the period 1992-2010, otherwise, most records are from coastal localities.
 
Life cycle
One generation. Overwinters as a small larva, during July to early June, pupating among plant debris.
 
Larval foodplants
The larvae feed at night on Gorse and Broom.
 
Identification
The darker cross-lines on this emerald will separate it from other emeralds.
 
Habitat
Heathland, moorland, scrub and open woodland.
