You're an entomologist who specializes in flies, which you affectionately refer to as diptera. Your goal is to capture flies for your collection. But to get a good specimen, you need to capture the flies alive.
Flies start out with the screen to themselves.
When you're ready, press the button to release the trap, reducing air space. To capture flies, release the trap repeatedly until the winged vermin have no more room to zip around. Tucows Inc.
