What is this fly?
Apologies for the bad photo but these guys are fast flyers and it's the best I can get. For almost 2 weeks, we keep getting these things in our bathroom. No idea how they're getting in. We've had the window shut, the vent shut and they're still somehow appearing. I would describe them as an angry, fatter ant. Two little antennas on their head, two back legs slightly apart. I know this is a long shot, but I hate not knowing what they are. If it helps, I'm in the UK
