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!

Stiletto Fly (Thereva nobilitata)

The pointed abdomen of this species and its relatives have led them to be called stiletto flies. This species reassembles the group known as robber flies and shares some of their characteristics. The are rarely seen on flowers preferring to wait on leaves for passing small insects which they dart out and attack. They have a lot of hairs which protects them against struggling prey.

The larvae are found in leaf litter and are omnivorous eating both rotting vegetation and taking live prey. The adults can be seen from May to August but are most numerous later in the summer when they often form large mating swarms.
