Hi all – I know there have been long discussions about attracting moths here in the forum already, but I’m still unsure what to buy. I don’t necessarily want to attract large numbers, but I am interested in maximising species diversity. I am not that much into assembling stuff, especially when it comes to electronics; I’m looking for something very easy, and relatively cheap. I don’t want to catch things but directly photograph them as they settle down. So far I did some tests with equipment I had already available (a LED floodlight directed at a somewhat reflective white plastic mat I suspended vertically on a tree) with some success at just 6° C (e.g., https://www.inaturalist.org/observations/35992787). However I still saw moths flying by that remained completely uninterested. I thought I could have more success with a blacklight in addition to the normal floodlight.
- Would you buy a UV bulb (7 W) or a stronger torch (~100 LEDs)? I imagine that a bulb is more powerful and shines in more directions. A torch would be portable though.
- Are you wearing UV protection glasses? I can imagine that with a bulb it is more difficult not to look into the light compared to a torch. I assume that a weaker torch (less LEDs) would drastically reduce success?
- Is a slightly reflective white plastic sheet effective or should I use cotton instead? Could the reflective surface be a problem for the eyes in combination with the UV light?
Thanks for any advice!
