Are moths attracted to wavelengths of ultraviolet light that we cannot detect? If so, a suitable emitter would solve your problem. You can purchase ultraviolet LED flashlights, which are still in our range of vision, but might not interfere with observing if set behind a shield and pointed away from your telescope. They are great for spotting scorpions, too! I doubt moths are attracted to infrared, otherwise I'd suggest that. An easy source of IR is a remote control, should you want to experiment.

One problem with collecting moths is that one sits and twiddles thumbs (unless there is someone along as company, but usually I go out alone) waiting for them to come in. Why not observe in the mean time? One problem with doing this is that light is needed to collect moths which interferes with observing. Some collectors use a mercury vapor light to attract moths from long distances, but I just use a black light (a neon tube about a foot long that produces a blue light) and my coleman white gas lantern. What I could do is take along my portable observatory, but for a one night stay it would be too much to drag along and set up. I could buy one of the tent type portable observatories (that Ernie Williams pioneered years ago which seems to have been forgotten, or never known, by most). But then when I get to the site I have to 1) set up the sheet and other associated equipment, 2) get the van in shape for a nights sleep, 3) set up the tent portable observatory, 4) set up the LXD75, and make my supper sometime in between all this. Arrrgghh. Too much work. Maybe if I live long enough our technology will produce a 'Stepford' Companion (a take on 'Stepford Wives', remember the movie?) that can do most of this stuff for me.
