regarding the UVB source, unless you’re relying on fluorescence, i wonder if that might be outside the range of light visible to moths?

@pisum

i read somewhere that insect vision starts to phase out around 550nm to 650nm (yellow to red) and ends on the other end at around 300nm. i use a 365nm light as my UV source, and it does seem to attract mostly small insects. if i add a white light (which should have a mix of other wavelengths), i attract other things. i’ve been thinking about getting a 395nm light, since i read somewhere that 400nm seems to be the best wavelength for attracting a wide range of insects.

@pisum

just note that the insects you attract at 400nm (ex. large moths) may be different than the insects you attract at 365nm (ex. flies). also note that if your shades are cloth, they may fluoresce and glow brightly (in the visible spectrum) when exposed to UV light
