When you use a sheet with different light sources it removes the possible impact of different trap designs. I am trying different trap designs with varying lights. In the last two years I have found that a 125W MV on a robinson catches the micros right down to the nepticulids (and many of them) whilst a twin actinic on a Skinner never caught any nepticulids and few micros but was good for larger moths especially noctuids and Hawk-moths. So I designed a robinson type trap of small stature with a 40W actinic. This also rarely took micros and did take larger moths despite the reduced size. This year I have one I am putting a twin actinic on a robinson trap to see how that does and have purchased the 20W actinic/blacklight that runs straight off mains to see how that pans out. This is a compact so if the issue is that the actinic tubes are not a sufficiently point source (rather than overall lumens) of light I shall get around that. I shall look forward to more of your reports on this.
