Dipterists Forum Hoverfly Newsletter Number 67 Spring 2020 ISSN 1358-5029 . On 21 January 2020 I shall be attending a lecture at the University of Gloucester by Adam Hart entitled “The Insect Apocalypse” the subject of which will of course be one that matters to all of us. Spreading awareness of the jeopardy that insects are now facing can only be a good thing, as is the excellent number of articles that, despite this situation, readers have submitted for inclusion in this newsletter. The editorial of Hoverfly Newsletter No. 66 covered two subjects that are followed up in the current issue. One of these was the diminishing UK participation in the international Syrphidae symposia in recent years, but I am pleased to say that Jon Heal, who attended the most recent one, has addressed this matter below. Also the publication of two new illustrated hoverfly guides, from the Netherlands and Canada, were announced. Both are reviewed by Roger Morris in this newsletter. The Dutch book has already proved its value in my local area, by providing the confirmation that we now have Xanthogramma stackelbergi in Gloucestershire (taken at Pope’s Hill in June by John Phillips). Copy for Hoverfly Newsletter No. 68 (which is expected to be issued with the Autumn 2020 Dipterists Forum Bulletin) should be sent to me: David Iliff, Green Willows, Station Road, Woodmancote, Cheltenham, Glos, GL52 9HN, (telephone 01242 674398), email:
[email protected], to reach me by 20 June 2020. The hoverfly illustrated at the top right of this page is a male Leucozona laternaria.
