Then, again to the Bert Bos path through the Westbroekse Zodden.

A £5,000 grant is set to boost the chances of southern damselflies that were released to an east Devon nature reserve last summer: here.

In several animal species, discrete, heritable phenotypic morphs occur in one sex only. This phenomenon is commonly observed in damselfly species where the coexistence of different female colour morphs is often explained in the context of sexual conflict. However, theories based on sexual conflict alone appear to be insufficient for explaining the inter-population variation in morph frequencies. A case in point is the widespread North American damselfly Nehalennia irene, in which one female morph occurs predominantly in populations in Western Canada, while another morph is more common in Eastern Canada: here.
