How does the horsefly trap work?
The horsefly trap catches horseflies by misleading the female horseflies. The black ball is heated by the sun and gently moves back and forth through the wind.
The horse fly is attracted by the moving heat source, lands on the ball, stabs and flies up (to the light).
She ends up in the collection reservoir via the trap.
