Best light source for catching?

[Bunyan van Asten]

I'm going out to catch some beetles, moths, ant queens and butterflies with a friend soon, we have eveeything set, but we can't really figure out the best light source, we're thinking of UV/LED, but we aren't quite sure
Could anybody give me some insight on what light source is the most effective?

ants are mostly attracted to wavelengths of 420-490nm and uva, uvb, uvc are below 400nm blue aquarium leds are best for it their wavelenght are mostly between 400-500nm
