This was photographed at night. It looks like a midge? Roughly 4-5mm long. Two very fine hair-like processes extend from the end of the tail and were longer than the rest of the insect. Through the time I watched it, it moved its tail from side to side continuously. Any information would be appreciated, thanks,

Baetidae
John is right. This is a female baetid imago, and "tail-wagging" is a habit of these little mayflies.

 
Thanks
Thanks for the ID, that's very intersting.

Hmmmm...
could it be a mayfly (Ephemeroptera)? Here is a tail wagger I had

 
mayfly
Yes, it might well be, thanks
