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!

Tachina fera: a parasitic fly

Some species of wildlife are exquisitely beautiful to the human eye, some are considered down right ugly but, regardless of human perceptions in this way, all species are quite fascinating. Well, I think so anyway. 
By human standards this parasitic fly (Tachina fera) is an unpleasant character all round, not just in looks, but because it parasitises butterfly and moth larvae, usually one grub per host. It is identifiable by its rusty colouring on the sides of the abdomen, fera being iron which rusts.
I took this photograph on brambles near the reed beds along the River Frome at Swineham Point, near Wareham and my book says it is often common on waterside plants in late summer.
