Aeshna isoceles (Green-eyed Hawker/Norfolk Hawker)

Termed the Norfolk Hawker in Britain because its range was originally restricted to Norfolk. However, it’s breeding range has now spread as far as Cambridgeshire so Green-eyed Hawker, the name suggested by Dijkstra/Lewington, which has always been more appropriate in a European context , is also more appropriate here, now.

Whatever we call it, we made a trip up to the Norfolk Broads in search of these delightful creatures and managed to find a good selection. They may be tagged as rare but they seemed locally abundant to me.

  • Distinctive/diagnostic yellow triangle on dorsal side of S2
