Acronicta alni (Linn.) (Apatele alni) Alder Moth p80. Resident, rather local and not common. Even after due allowance is made for the advent of the MV lamp to which this species is readily attracted, it has almost certainly increased in numbers and extended its range as the VCH described it as very rare. A total of 32 to light in a 70 Little Baddow garden in 1984 (SW) is exceptional. Acronicta tridens (D. & S.) (Apatele tridens) Dark Dagger p81. Resident, fairly widespread and locally fairly common. Acronicta psi (Linn.) (Apatele psi) Grey Dagger p81. Resident, widespread and common. Acronicta rumicis (Linn.) (Apatele rumicis) Knot Grass p81. Resident, widespread and common. Simyra albovenosa (Goeze) (S. venosa Borkh.) Reed Dagger p81. Resident, very local; still generally scarce but increasing in numbers and extending its range; mainly confined to the coast and estuaries and their vicinity. 68 Stanford Warren NR, a number 1983 (DJLA, CP, PAS); 90 Bradwell-on-Sea, continues to occur almost annually (AJD); 00 Bradwell-on- Sea, 1983 (CP et al); 09 Dengie (AJD, SFJD): 01 Fingringhoe Wick NR, 1976 (PJW); 02 north Colchester,1979 (JY); 22 Hamford Water, four 1982 (MEA, RL). 88 Thundersley 1984 (DGD). Craniophora ligustri (D. & S.) The Coronet p81. ?Vagrant, very rare; only one recent record, on 70 Danbury Ridge, 1969*. Cryphia domestica (Hufn.) (C. perla D. & S.) Marbled Beauty p80. Resident, widespread and locally common. Amphipyrinae A large subfamily of mainly medium-sized moths. The larvae are hairless. Some species feed on roots, others burrow in the stems of their foodplant and many others have the more normal habit of feeding on leaves. Some species overwinter as eggs. Over 100 species have been recorded in Britain of which 72 have been found in Essex, as well as two which were accidentally introduced from abroad in plant material (see Appendix, p 118). Amphipyra pyramidea (Linn.) Copper Underwing p79. Resident, widespread and locally common. 101
