   Annie Pang sends a picture of a nematoceran fly on her wall.  Jeremy Tatum writes:

It is almost certainly a winter gnat of the family Trichoceridae, although there are some small species of crane fly (Tipulidae – Limoniinae) that look quite similar and which fold their wings gnat-fashion rather than in more typical Tipulinae.  Beyond family level I dare not go.  Limoniines often bob up and down while at rest.  Readers who see a suspected limoniine or trichocerid should keep a look-out for this limoniine habit.
