Whats a drain fly?

They're tiny (about 1/16 - 1/8").  I wasn't aware of them until a couple of years ago when I disconnected a sink and they emerged from the drain pipe.  Once I reconnected they disappeared but over the past few weeks I've had a load of them.  Just wondered if the recent weather conditions had caused a general problem or whether it's just a problem at my place.  There's a load of info about them on t'internet.  I tried inserting a pic but couldn't get it to work.
