History
The earliest notification of this species is published in Stephens (1829) with the Rev. William Little recording it at Raehills (VC72).
 
Lennon (1863) had found it at Dalskairth (VC73). K. J. Morton of Edinburgh (1900) whilst on a visit in July 1899 to Wigtownshire had found this species in the Monreith area. Gordon (1919) found it to be common and generally distributed in Wigtownshire. Earliest date was 15th June 1911.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72).
 
During 1974-93 all seven Rothamsted stations provided three hundred and fifty records, proving it widespread.
 
From 1993 to 2010 the regular trapped sites at Kirkton, Durisdeer and Cally Woods were responsible for good numbers of records, with the rest coming from widely scattered sites across the region.
 
Life cycle
One generation. Overwinters as a pupa underground. Larvae are present from July to early September.
 
Larval foodplants
Larvae feed on Common Hemp-nettle flowers and seeds.
 
Identification
Smaller than The Rivulet and with two small indentations on the basal side of the white cross-line as against one on The Rivulet.

A wide variety of habitats.
