Wait until evening to see who comes to dinner. Sink a jar or can into the ground so the lip is at or slightly below ground level. It can be baited with the above recipe, or try your own lure to see what works. A board or log placed above the trap will help the trap work more efficiently. Insects roaming on the ground will fall into the trap.
Light is also a good attractant when used at night.
One method is to hang a light with a white sheet as a backdrop. The sheet provides a place for the insects to land, and a good place for you to see them. A second method is to hang a light over a large funnel that is resting on top of a jar. The bugs are attracted to the light and then fall into the jar. Entomologists have created a standard way to pin insects so you can easily study them and know the date, location, collector and species name.
