A simple beginner's midge pattern to tie. A size 14-18 fine wire hook, an abdomen of one barb of pheasant tail and one strand of green kystal flash wrapped up the shank together. The hackle is one wrap of dry fly quality grizzly and the small tab of foam in figured eighted atop the shank and then covered with a few wraps of peacock herl. The rear end of the fly will ride slightly downward and the wing/foam will support the fly in the film. SwittersB

The fly fishing literature will advise you that midges-chironomids-buzzers are available year around as a dry fly/emerger option. The above pattern is, at a size 16, on the large size for most streams/rivers, but suitable for many lakes. 

Study up on the larva, pupa, emerger and dry fly patterns that work from the muck up onto the surface. Dry, Emerger, and droppers are suitable for rivers, but you are advised to know your larva/pupa patterns when fishing  the vertical presentation of a lake.

By no means the only resources, but you would be well served to study UK and BC literature on how to tie and present Chironomid patterns. The buzzer, midge, gnat, chironomid/bloodworm designations are more regional in use and in no way are separate insects. As a rule, the UK=Buzzer, BC=Chironomids and the US=Midge….are uniform in tying and presentation, with variations, of course, as in all fly tying/fly fishing.

The midge patterns are simple to tie (particularly larva and pupa patterns) yet very effective. They are always there, so have the necessary assortment of options.
