Earias clorana (Linn.) Cream-bordered Green Pea p88. Resident, very local and scarce; all occurrences have been on or near the coast and estuaries, particularly on Thames-side. 48 East Ham. 1983 (CWP); 58 Rainham, two 1981 (GSR); 67 Grays (DJLA); 68 Thames-side, 1977-78 (RT); Ol Fingringhoe Wick NR, larva (reared) 1976 (AME); 23 Dovercourt, 1976 (MEA). Bena prasinana (Linn.) (Pseudoips bicolorana Fuess.) Scarce Silver-lines p87. Resident, widespread and locally fairly common. Pseudoips fagana (Fabr.) (Bena prasinana sensu auctt.) Green Silver-lines p87. Resident, fairly widespread and locally fairly common. Sarrothripinae There is a single confirmed British resident species which resembles, and is often mistaken for, a member of the Tortricidae (microlepidoptera). Winter is passed as an adult. Nycteola revayana (Scop.) Oak Nycteoline p88. Resident, apparently rather local and scarce but easily overlooked. Pantheinae The single British resident species resembles an acronictine both as an adult and a larva and is included in that subfamily by some modern systematists. Colocasia coryli (Linn.) Nut-tree Tussock p90. Resident, rather local; locally common. In the extreme north-east now known to be common in 13 Stour Wood and 23 Copperas Wood NRs (MEA, PS): see Guide. Pluilinae Most of the British species have prominent metallic markings on their forewings. Many of the 23 British species are migrants, mostly rare but one, the silver Y, often abundant Some come from as far away as Africa. The larvae, most of which have only three pairs of prolegs, feed mainly on herbaceous plants and generally overwinter in this stage. Of the 15 species that have occurred in Essex, eight are migrants.
