The Moths of Suffolk
1673 Small Emerald, Hemistola chrysoprasaria, (Esper, 1794)

National Status : Local

Local Status : Resident (SMP Status 1)

Distribution and abundance : Widespread but at low density

Habitats : Open woodland, grassland, gardens

Flight Period : Single-brooded; late June to August, occasional records in September

Larval foodplants : Traveller's joy

Comments : Maybe under-recorded as it is suspected that it is weakly attracted to light. In line with Morley's comments it appears to be more common at sites chalk is near to the surface, although in general it appears records are now more widespread.

Morley's Final Catalogue : Distinctly local, common only on chalk strata and not following clematis on the chalky boulder-clay. Sudbury (Ransom); Copdock on 16 July 1896 (Hkg); Bentley (Ml); Ipswich in 1893 (Pyett); common at Claydon and Barham (Sparke), many among clematis at Barham Green on 14 July 1899 (Mly); Stowmarket; Bury (Wrt, Ent. ii, 340; Sparke); Hardwick. Recorded in the east at Aldeburgh and Beccles, but not since 1890.

Wingspan details : Forewing 17-20mm, Wingspan 33-40mm
