Davey, P., 2009: A recent addition to the British list, first recorded in 1999 in Kent and subsequently found in Dorset the following year, the larva feeding under the bark of pines (Pinacea spp.), and causing wounds to appear on the trunk from which resin exudes. In mainland Europe, where it is widespread, it is considered to be a pest with the potential to degrade the quality of timber. The moth now appears to be resident very locally in pinewoods in the Poole Basin, and spreading rapidly west and north. It has similar habitat preferences to Dioryctria simplicella1455, and may, in time, share a similar distribution: Shaggs, at MV light on 1 August 2001, 29 July 2002, 6 August 2002, 10 October 2002, 13 July 2003, 11 August 2003, 12 August 2003, 13 August 2003 (M Parsons), Higher Hyde, at MV light on 23 July 2002 (P Davey), Trigon, on 28 July 2000 (C Manley). Twenty individuals were recorded in 2005 and more than one hundred and twenty moths were recorded across the county during 2006.
