Nature Conservancy Council Review of the Lepidoptera of Essex for the year 1998 BRIAN GOODEY 298 Ipswich Road, Colchester, Essex CCI4 4ET Introduction There was much of interest reported by our recorders during 1998 despite it being an often difficult year weather-wise. Three moths were added to the comity list, which now totals 1843 species. Of these 1835 have been accepted by the Lepidoptera Panel as being substantiated records, and 1448 arc regarded as insects able to survive our climate in Essex throughout the year. Species levels remained much the same but numbers of insects were generally well down on last year. This included many leaf-miners, our smallest moths, and larger 'sparrows' such as heart and dart and dark arches. Our large hawk-moths, by contrast, did very well. The Essex Moth Group continues to do well. Articles which appeared in its newsletter included the rediscovery of Depressaria daucella in Essex (David Warner), an update of the gypsy moth situation in Epping Forest (Jes Dagley), and a discussion on the ichneumon wasp Amblyjoppa proteus (Jerry Bowdrey) which attacks larvae of the large elephant hawk-moth. Whilst on the subject of Hymonoptera it is worth mentioning that hornets and wasps were something of a menace for many recorders this year. Some traps were left in the morning with just a few scaltered moth remains in the bottom after a night of carnage. People out in the open Essex Naturalist (New Series) 16 (1999)
