Identification pitfalls (part 1)

With a bit of luck this will become a regular feature of my blog. The aim will be to provide reference illustrations relating to particularly difficult species pairs found in Gwent. In future, I hope to be able to add tips on how to separate the species involved, however, with these two, all I can suggest is that there must be some differences in wing formula or maybe moult schedule. Uncanny, isn't it.
