About Me

My photo

I have been interested in nature for most of my life but since I retired I spend as much time as I can exploring the nature reserves and wildlife hotspots of my adopted home, Dorset in southern England. Whilst out I record what I see and take snaps where I can (I am no photographer!) and that forms the basis of my Nature of Dorset website. When I find something new I like to research it and write about it in my nature notes, it is how I learn and hopefully you might find my notes helpful as well!

This website is for the people of Dorset interested in wildlife and for people from elsewhere interested in the wildlife of Dorset!

Dark-green Fritillary: flap flap glide | Nature Notes from Dorset

Three things stand out for me with the dark-green fritillary (Argynnis aglaia) which can help with identification as fritillaries can be quite difficult to tell apart unless you get a good view of them.
Firstly, the dark-green fritillary is very much a butterfly of open chalk grassland and downs where there are good quantities of flowering plants to nectar on whereas the other fritillaries would not be seen in such surroundings. Secondly, the dark-green fritillary has a very strong, direct flight and has intermittent glides between wing beats. I am not sure any other species of butterfly actually does this. Finally, it is not dark green! Well, not at first sight at least. This is a wonderful large, orange and brown species but, if you see it at rest on a flower you will see the underside of the wing is, indeed, partly dark green.
