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!

Silver Studded Blue (Plebejus argus)

Dorset is home to a number of very rare butterflies and the Silver Studded Blue is certainly one of them.

A small butterfly, it is smaller than a Common Blue with much brighter markings on the under side of its wings. It is quite distinctive in habitat, however, as a heathland butterfly
and can be found from late June until early August on the heathland of Purbeck, notably at Arne. It also occurs on grass downland and can be found on Portland too.

Being a heath specialist, it is not surprising that it's favoured food plants are Gorse and Broom and the larvae also feed on heather and Bird's-foot Trefoil.

Blue butterflies are in general lovely insects and the Silver Studded Blue is certainly one of the best.
