We hold free and heavily subsidised invertebrate workshops and webinars on identification, recording, curation and field craft to help boost the skills of beginners and experienced entomologists alike. These are complemented with drop-in sessions to facilitate mentoring and networking. We also run an invertebrate recording day programme to bring together the invertebrate recording community and facilitate improvements to baseline data coverage at selected important / under-recorded sites.

Hoverflies: In-person workshop

19th November | 10:30 am - 4:00 pm

Course content: Hoverflies (Syrphidae) are probably the most recorded and popular family of Diptera (True Flies) with over 280 British species. Many of these attractive insects can be identified in the field although the majority need to be examined under a microscope. This course will be aimed at people with little or no experience of hoverflies. However, it is hoped that more experienced attendees will learn additional information about them, their collection and identification.

The one-day workshop will begin with an introductory presentation/talk outlining the ecology of hoverflies and currently available identification resources. This will be followed by laboratory practice in the use of microscopes and identification using dichotomous keys. Specimens from the World Museum’s collection will be used for this purpose, although attendees are welcome to bring along their own for identification. If time and weather permits, it may be possible to collect (and identify) some in the wildflower garden at the front of the museum. At the end of the day, it is hoped that everyone attending will have gained valuable experience in identifying hoverflies to at least tribe/genus level.

Tutor information: Glenn Rostron is the county hoverfly recorder for Cheshire and Lancashire (vice-counties 58,59 and 60). He is an amateur entomologist and arachnologist who specialises in various groups of diptera, hymenoptera and arachnids. He has been studying hoverflies for a decade, having first become fascinated by them after attending a presentation on them which was given, as part of his MSc Biological Recording course, by Stuart Ball and Roger Morris who jointly run the national Hoverfly Recording Scheme.
