Review of the Lepidoptera of Essex for 1999
89
0174 Heterogenea asella (Denis & Schiffermuller) Triangle Beaumont-cum-Moze TM1625, 17
July (J.B. Fisher). Fourth recent Essex site. Also appeared during July at its better-known
localities of Copperas Wood, five adults, and Stour Wood, 22 adults (P. Smith et al), making
this a good year for the species. 4DBR
Tineidae
0220 Nemapogon clematella (Fabricius) Colchester, High Woods Country Park TM0026, 23 June
(B. Goodey). Netted at dusk. More frequent in north-west Essex: Emmet, 1981 lists four lo-
calities and it occurred at Saffron Walden in 1985 and 1996. Else where this distinctive species
is very scarce. 2DBR
0237 Niditinea fuscella (L.) Thundersley, Woodend Close 17 July (D. Down). Third record from
this garden. Saffron Walden (once) and East Ham (twice) arc other localities, both in 1990.
3DBR
Gracillariidae
0363 Phyllonorycter platanoidella (Joannis) Jaywick, mines on Norway Maple at TM1312, 14 July
(J. Young). The other recent record is High Woods CP, in 1991. 2DBR
0368 Phyllocnistis unipunctella (Stephens) Jaywick, mines discovered on White Poplar Populus
alba at TM1312 on 3 August, a new foodplant for this species (J. Young and A.M. Emmet).
4DBR
0369 Phyllocnistis xenia (Hering) Colchester, Ipswich Road TM0126 on 17 July at mercury
vapour (B. Goodey). Known from Kent and possibly a few other localities in southern
England. New to Essex
Sesiidae
0370 Sesia apiformis (Clerck) Hornet Moth Chelmsford, a winter survey by G Wilkinson
revealed many new larval sites and, later, adults on Populus fringing the Chelmer. Other new
sites are Harlow (M.J. Pledger per CW. Plant) and Chadwell Heath (S.L. South). 34DBR
Choreutidae
0389 Choreutis pariana (Clerck) Dovercourt, Oakley Road TM2230, three on 1 and 23 July, and
9 October (C. Gibson). Two other post-1990 sites arc Saffron Walden and Kirby-le-Soken.
3DBR
Yponomeutidae
0409a Argyresthia trifasciata (Staudinger) Colchester, Ipswich Road 26 May (B. Goodey).
Adults boxed during the day, showing reluctance to fly, and later at mercury vapour. Found
on Chamaecyparis lawsoniana and x Cupressocyparis leylandii together with next species.
Likely to be widespread if searched for, but known British sites at present probably number
less than fifteen. Fust recorded in Britain at London in 1982 (Emmet, 1982). New to Essex
0409b A, cupressella (Walsingham) Colchester, Ipswich Road, a number of adults 26 May and
cocoons on x Cupressocyparis leylandii 10 June (B. Goodey); Dovercourt, Oakley Road 10
June (C. Gibson). Significant range extensions from the area of Suffolk and north Essex where
it was first discovered in Britain in 1997 (Agassiz & Tuck 1999), and it is likely to become
something of a garden pest though larval feedings are not unsightly. 3DBR
0428 Yponomeuta rorrella (Hubncr) Tollesbury, Old Hall Marsh RSPB reserve TL9612, larvae
collected on Crataegus during the summer and reared to adult stage (D. Warner). A hitherto
unknown foodplant in Britain; the usual pabulum is Salix spp. 3DBR
