There were quite a few of the very active flies.
However they would always seem to land close to where the took off from.

Robber fly, family Asilidae
Hello Charles,
This is a robber fly in the family Asilidae!
Greetings,

Robber Fly
Gerard;
Thanks for the ID.
I was wondering if it was one of the robber flies because of the spines.

 
Robber
The spines are not important. But the depression between the eyes is.
This is an Atomosia species. Possibly it is A. puella but there may be lookalikes in the great north.

 
Most of the times: look at the head
Most of the times, when the head is well visible, you can see there is a depression between the eyes and often in the depression you can see the ocelli on a small raised part. Nearly always it will then be Asilidae.
