TRANSACTIONS SUPPLEMENT TO THE FINAL CATALOGUE OF
THE LEPIDOPTERA OF SUFFOLK INCLUDING THE 62 ADDITIONS BETWEEN 1937 AND 1960. by ALASDAIR ASTON. THIS list is meant to facilitate reference for any entomologist working on the County List. The additions are printed in the order of the 1937 list and the first number refers to the position of the species on that List. The second number refers to the order of addition to the list down the years. Consequently the next species new to Suffolk will be numbered 1568. I have not been able to discover who is editing the next edition of South's " Moths " but it is hoped that here will be found much useful information for that publication. Similarly, if the " British Pyralid and Plume Moths " of Bryan P. Beirne is edited again, it is to be hoped that mention is made of a list more recent than that of Morley and Bloomfield, 1911. This Supplement deals only with NEW species, but it should make the entomologist's task a little easier. It is important to remember that the 1937 list has, itself, 5 additions printed at the end. These additions may seem to present a cheerful view of our lepidoptera, but possibly as many species have disappeared as have arrived. Spraying has made the continuance of any insect fauna at all problematical. Apart from that, some of these insects are not permanent residents. Others are recent arrivals to the British Isles. Some of these may settle permanently, but others may withdraw. There has been a marked increase in coniferous feeders and this with the arrival of several birch feeders and other northern species may have something to do with the activities of the Forestry Commission. The largest single additional factor has probably been the general use of light, and particularly of Mercury-Vapour light, in collecting. I am most grateful to Mr. S. Wakely for the trouble he has taken in identifying my microlepidoptera and to Mr. Chipperfield for his general encouragement over the last twenty years.
