The Brad Ashby Memorial Lecture (online)

Inspired by Caddis…Adding value to biological records

The British Entomological and Natural History Society and the London Natural History Society are delighted to announce that this year’s Brad Ashby Memorial Lecture will take place online and be presented by Dr Ian Wallace, the current National Biodiversity Network’s ‘Terrestrial Wildlife Recorder of the Year’ and renowned caddisfly enthusiast.

For over forty years, Ian Wallace has co-ordinated the National Caddisfly Recording Group, transforming understanding of what was previously a poorly understood group of insects. There are now over half a million caddis records on the National Biodiversity Network’s Atlas and Ian is happy for them to be regarded as ‘honorary moths!’

Throughout the lecture, Ian will be drawing on his experiences of studying caddisfly biology. He will be identifying gaps in knowledge, praise both casual and systematic recording, and explore wider issues relating to the quality and conservation value of UK wildlife records. In doing so he will enter into short, separate conversations with four leading invertebrate conservation practitioners:

Sharon Flint – Freelance ecological surveyor and educator.

Martin Harvey – Research Associate, Scientific Data Support, Biological Records Centre, Centre for Ecology & Hydrology.

Dr Mike Howe – Senior Invertebrate Specialist for National Resources Wales.

Craig Macadam – Conservation Director for Buglife and organiser of the Mayfly and Stonefly Recording Scheme.

This will be followed by a question and answer session.

This lecture is in memory of C.B. Ashby 1920-1994


Presenter: Dr Ian Wallace

Ian Wallace has been recording caddisflies since the 1970s. Since establishing the Caddisfly Recording Scheme, he has personally amassed over 410,000 records! These days, Ian probably spends as much time helping other people identify caddis, especially from photographs, as doing his own recording.
Ian was the winner of the 2019 NBN Award for Terrestrial Wildlife. He was a senior curator at National Museums Liverpool (NML) for over forty years.
He is currently an Honorary Curator at NML and an Honorary Fellow of the Freshwater Biological Association (FBA). His most widely used publications are probably his FBA Cased Caddis Larval Key, The FSC Simple Caddis Larva Key and reports for Natural England on the conservation status and distribution of the UK Caddis. Coming soon (2021) will be his Atlas of the Caddis of the UK and Ireland and also a Guide to Identifying Caddis Adults when they are alive or in photographs.
