A disappointing observation

Tonight, I set up a white sheet in my yard, with a bright LED pointing at it, to see what insects would be attracted to it. It was pathetic.

After 45 minutes, 10pm to 10:45, all I found was a handful of moths, 20 or 30 tiny little flies, and about 10 mosquitoes. I’ll try again a different night with an additional UV light source, but this was mediocre. Nothing substantial enough to even feed an adult spider.
