Argynnis adippe

HIGH BROWN FRITILLARY Argynnis adippe

As with the previous species, this one occurs in the open woodlands around Morecame Bay (SD47), and is usually fairly abundant in suitable places in July. Its flight time is later than that of the smaller "Fritillaries" and although it uses the same larval hosts (Violets) it does not seem to compete with them. It is however coming to find itself increasingly in competitionwith A. aglaja, and more recently A. paphia. In the late 1980s it seemedto have the monopoly of large Heliconiines at Gaitbarrows, but latterly A. aglaja has spread into that site. Further west but still in square SD47, just over the vice-county boundary at Arnside Knott (VC69) in the early 1990s A. adippe was quite definitely the dominant large Heliconiine, but latterly A. aglaja has all but supplanted it. Further west still, at Roudsea, in the Furness (historically in Lancashire, but not included in the maps in this work as it is regarded as being in VC69), A. adippe has been almost completely supplanted by A. paphia, and indeed A. aglaja, which in 1992 seemed to be co-existing with A. adippe in about equal numbers, seems to have become scarce there.
