An interesting pair of photos from Longford Park last month, courtesy of Steve Gresty.
The first given below shows a definite immature Scarce Blue-tailed Damselfly of the orange (aurantiaca) form.
However the second photo is considered by both Adrian Parr and Steve Hewitt to show an immature Blue-tailed Damselfly of the form rufescens-obsoleta. To arrive at this conclusion, these experts mention a number of features, the clearest of which is the presence of the post-ocular spots which are typical of Blue-tailed but not Scarce Blue-tailed.
