MOTHS OF REDGRAVE AND LOPHAM FENS Fourth Report C . W . PLERCE
IN spite of three visits only being paid during the season, eighteen species of the Macro-lepidoptera have been added to the list, bringing the total to 304. The first visit took place during the evening of 3rd July, when I was accompanied by Messrs. H. E. Chipperfield and R. Luff. Conditions were by no means ideal, but we were able to record a total of forty-nine species. Recorded for the first time were the Rustic Shoulder-knot (Apamea sordens), Pale Mottled Willow (Caradrina clavipalpis), V Pug (Chloroclystis debiliata), and the Fern (Horisme tersata). Other interesting species included the Elephant Hawk (Deilephila elpenor), ButT Arches (Habrosyne pyritoides), White Satin (Leucoma salicis), Round-winged Muslin (Thumatha senex), Dotted Fanfoot (Zanclognotha cribrumalis), Southern Wainscot (Leucania straminea), the New Gold-spot (.Plusia gracilis), and the Gold Swift (Hepialus hect채). The Fens were visited in daytime on 22nd July, when beating the scrub produced the Treble-bar (Anaiiis plagiata), Brownsilver Line (Lithina chlorosata) and the Small Emerald (Hemistola immaculata). A Caterpillar of the Muslin Moth (Cycnia mendica) was found crawling near the Hut. Mr. R. Luff and I met Mr. H. E. Chipperfield and Mr. G. Baker on the Fens just before dusk on 7th August, when eighty-nine species were recorded, including seven for the first time. These were the Chocolate-tip (Clostera curtula), Dotted Clay (Amathes baja), Straw Underwing (Thalpophila matura), Yellow-barred Brindle (Acasis viretata), Tissue (Triphosa dubitata), and Dark Umber (Philereme transversata). Confirmation of the Rev. G. Ford's record of the Minor Shoulder-knot in 1950 was obtained when three specimens appeared on the sheet. Haworth's Minor (Celaena haworthii) was present in small numbers as were the Fen Wainscot (Arenostola phragmitidis), Small Rufus (Coenobia ruf채), Double-lobed (Apamea ophiogramma), Powdered Wainscot (Simyra venosa), Twin-spot Wainscot (Nonagria geminipuncta), and Silver Hook (Eustrotia uncul채). Single specimens of Dog's Tooth (Hadena suas채), Rosy Minor (Procus literosa). Stout Dart (Spaelotis ravida), Crescent (Celaena leucostigma), Sallow Kitten (Harpyia furcula), and Dusky Sallow (Eremobia ochroleuca) turned up.
