Here’s one I made for attracting rare sand dune beetles. They don’t fly but are attracted to UV lights. The tripod is a basic one with a hook on the central post, the tube is a plastic core from a roll of plotter paper and the lights are white and UV led ribbons from Amazon. I think the lights, switches, and a 12V RV battery cost about $50. We set it up on a large white sheet and all kinds of insects come to it.
There’s a rope through the middle of the tube to hang it and separate switches for the white (yellow when turned off) and UV (silver when turned off) lights.
The bottom has a power plug. When it’s windy I put a rock on the cord to keep it from swinging.
It fits inside a poster tube for easy carrying and to protect it in the car.
