Hesperiidae
1 532 Erynnis tages L. Dingy Skipper. Last County record occurred in
spring 1990 at 92 Friday Wood (BG) and the species may now be
extinct in Essex.

northern vice-county. Still occurs at several south Essex sites such as

plans to introduce this species to Little Baddow Heath NR from Sussex
stock.
