The Moths of Suffolk
2093 Sand Dart, Agrotis ripae, (Hübner, 1823)

National Status : Notable Nb

Local Status : Resident (SMP Status 3)

Distribution and abundance : Scarce, restricted to a few sites on the coast

Habitats : Coastal sandy beaches

Flight Period : Single-brooded; June to July

Larval foodplants : Various plants growing on the strandline

Records : Thorpeness (B Statham, 3.vii.1993, 2.vii.1994, vii.1998; A Prichard & G Bull, 12.vii.1997), Minsmere (C Anderson, 1994, 1995 & 1997), Landguard Common (N Odin & M Marsh, 2001, 2003-7), Bawdsey (M Deans, 14.vi.2006 & 4.vii.2006), Southwold (various, 2005), Dunwich Heath (D Brougham & C Moore, 11.vii.2006)

Morley's Final Catalogue : Confined to our coast-line in Suffolk; Barrett's expectation of discovering this species in the Breck appears unfulfilled nor is Salsola Kali, L., on which the larvae feed at Leiston, recorded thence. A good series taken during 1901-2, abundant during 1903, at Felixstow (Gibbs); Southwold (Bkr), Covehithe (Mly), Lowestoft (Crf, L); Gorleston (Mr, Wiltshire), and not rare just north of the Yare (D).

Wingspan details : Forewing 14-18mm, Wingspan 32-42mm
