Davey, P., 2009: A local fen, bog, heath and moorland species in Britain, the larva feeds on sedges and grasses. In Dorset, the moth is at low density in wet heathland and mire (the same habitat occupied by the Small Grass Emerald1670), falling within the confines of the Poole Basin. "Few suitable localities exist in the county, and it is not common in these, nor present in all of them." (W Parkinson Curtis ms). Wood-sedge (Carex sylvatica) and tufted hair-grass (Deschampsia cespitosa) are the two host foodplants named in texts, but these tend not to be found in an acid bog biotype in the county. Three sedges that occur frequently on the sites where moths are found are: common yellow sedge (Carex viridula oedocarpa), carnation sedge (Carex panicea) and star sedge (Carex echinata).
