Blossom Underwing Again

Blossom Underwing is a rare moth in Hunts (VC31). My first on 29 March 2004 was the tenth for the VC and was thought to be a migrant. However now I've trapped another in the garden I am wondering if there is a population locally. The Moths of Northamptonshire site shows this may be possible:

Totals from two traps:
1524 Emmelina monodactyla, 1
1917 Early Thorn (Selenia dentaria), 3
2183 Blossom Underwing (Orthosia miniosa), 1
