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!

Thelaria species: parasitic flies

You may not like them but you can't ignore them! Come the summer flies make themselves known to all of us one way or another; climbing our windows, buzzing round our heads, some even biting us. I doubt many of us actually like flies as, like rats, they are connected with spreading disease and that hatred is passed down from one generation of humans to the next.
This genus, thelaria, are particularly troublesome in some parts of the world carrying disease and parasites around people and, more frequently, cattle. The 260 or so species we have in this country are not such a problem, they are just an irritation.
What I find amazing is that to separate and classify these insects you need to examine them under a microscope as wing venation and genitals can be key to species identification. This one flew off shortly after being photographed, it may have thought I was a scientist looking for a positive identification and wanted none of that, thank you very much!
