Thu 23 Jan 2025. Electric Ecology; How Invertebrates Capitalise on Static Electricity
Dr Sam J. England | Museum für Naturkunde.
The Brad Ashby Memorial Lecture
Most terrestrial animals naturally accumulate electrostatic charges, meaning that they will generate electric forces that interact with other charges in their environment, including those on or within other organisms. Join us on a journey through the often unnoticed ecological role of static electricity in nature. Dr Sam England will discuss how electrostatic forces attract pollen onto butterflies and moths, allowing them to be more efficient pollinators; how the charge of tick hosts like cows, dogs, and humans, pulls ticks across air gaps to make them better parasites; and finally how many insects can detect static electricity, and use it to sense the approach of their predators.

Bringing Back the Chirp
30 Years of Cricket Conservation in Britain
Dave Clarke (Zoological Society of London)
The Field Cricket (Gryllus campestris) and Wart-biter Cricket (Decticus verrucivorus) are two of the UK’s rarest insect species, classified as endangered in Britain due to habitat fragmentation, loss of habitat and declines in habitat quality.
So, obviously, I had to look up Wart biter cricket…
“The Wart-biter was once used as a method for removing warts – it was put on an area adjacent to the wart and would slowly attempt to chew off the wart. Apparently it didn’t work very well, but was still used!”

Fisher’s Estuarine Moth
Spreading Its Wings in Essex
Dr Zoe Ringwood (Essex Wildlife Trust)
Fisher’s Estuarine Moth (Gortyna borelii) is a rare and threatened moth, with a UK distribution restricted to the north Essex and north Kent coasts. Much of its UK stronghold was recently lost to the sea as a consequence of coastal change. Luckily, the Essex Wildlife Trust had been preparing for this event for over two decades. This presentation will guide you through how the Trust has worked to secure the future of the moth in Essex, by establishing new areas of habitat and encouraging the species to move across the landscape.
Dr Zoe Ringwood has been working on the conservation of Fisher’s Estuarine Moth in Essex for over 25 years. She is part of a dedicated team of conservationists and farmers who have established new areas of habitat for the moth across the landscape, enabling the species to move away from the threats of coastal change and secure its long-term future. She currently works as the Head of Conservation Evidence at Essex Wildlife Trust.
The presentation will be recorded and shared with those who booked via a password-protected website following the event.
