Survey tips and notes - how to find elms, eggs, larvae, pupae and the adult White-letter Hairstreak

Andrew Middleton and Liz Goodyear of the Hertfordshire & Middlesex Branch have been looking for Purple Emperor for many years, and this work has focused their attention on assessing arboreal habitats and their associated species. They have found that many of the techniques that are so useful in surveying for Purple Emperor can also be used to find White-letter Hairstreak.

Martin Greenland of the Yorkshire Branch is an expert in finding White-letter Hairstreak eggs, larvae and pupae in the north of England.

In addition, the co-ordinators have tried to gather as much information from other recorders that have also spent a lot of time studying White-letter Hairstreak across the UK. We hope that these linked pages will be helpful.
