The chalk Grayling is arguably Sussex' rarest butterfly - in recent years its numbers have declined and it appears to be close to extinction.

In 2019 we are planning an extensive study of Deep Dene to find out why the Grayling has hung on there and nowhere else.

This will begin with a caterpillar survey. We are looking to recruit a dozen or more volunteers to take help us find out where the nocturnal Grayling caterpillars are and what they are feeding on.

We will be returning to the site the following day to study the soil and botanical properties of the places where caterpillars were found and compare them to areas where they were not.

Suitable for children, but they must be accompanied by an adult and suitable for dogs, but they must be on a lead.

You don't need any special skills, just a torch and the desire to do something that matters.
