Angelica sylvestris L., Daucus carota L. and probably other Apiaccac. When 

 young, the larva mines the leaves from the underside in short, squat mines, expelling 

 the frass in mounds at the entrance to the mine. Later feeding on the underside 

 of the leaf, often gregariously, in a slight web and producing 'windows' in the 

 leaf. Found from mid-May to September in two or three overlapping generations. 

 Overwinters as an adult, the moth can be found in all months of the year but is most 

 frequent from October to May and in July and August. The most abundant member 

 of the family, found throughout the British Isles. 



Epermenia aequidentellus (Hofmann), Plate V, Fig. 9 



Wingspan 9-12 mm. Forewing narrower than congeners. Ground colour variable, 

 normally light fuscous with areas of darker infuscation, especially medially and in 

 terminal areas, though in some specimens the ground colour is creamy-white or the 

 infuscation much heavier. There are four dark scale teeth on dorsum. Larva with 

 black head and prothoracic plate and yellow-green body with black or brown spots 

 and darker dorsal line. Feeds in May and June and again in August and September 

 on Daucus carota L. and Pimpinella saxifraga L., at first in a small blotch mine and 

 then later feeding externally in a slight web. The moth flies in June and July, 

 and the second generation in September and October. Local in Central-southern and 

 South-west England, found most frequently near the coast.

ANNOUNCEMENT 



Subscription changes — Following the decision taken at the Special Meeting on 

 14th September the distinction between 'Ordinary' and 'London' members has ceased 

 and a unified system of subscription has been adopted. 



The rates of subscription that will apply from 1st January 1994 and for at least 

 four years, payable on or before that date, will be: 



Ordinary & Corporate Members £12.50 



Junior Members £4.00 



Life Members £500.00 



With effect from this change it will be possible for members to covenant their 

 subscriptions and I would urge you to do this if you are a tax payer. Subscriptions 

 paid under covenant will be deemed to be paid net of tax and the Society will be 

 able to reclaim the tax suffered. Covenanted subscriptions will cost you no more but 

 will result in substantial benefit to the Society. A note of the covenant made should 

 be retained to help in completing your personal income tax return. 



Revised standing order forms and deeds of covenant were issued recently and I 

 would ask that these could be returned as soon as possible to the Assistant Treasurer 

 and in any case before 31st December. Prompt action on this will save the Society 

 considerable work and expense. — A. J. Pickles, Treasurer.
