I have also analysed my results from my simple experiment to compare trapping results using 2 different bulbs. A summary is included here. I have got a more detailed analysis with graphs. looking at time of year and species caught but I am not sure whether it is appropriate to share it here?
Throughout 2016 I attempted to find pairs of nights that were not more than a few days apart and with forecast weather conditions in terms of temperature, wind speed and rainfall as similar as possible. On one of the two nights I would run my Robinson trap with a standard 125W MV bulb and on the other night I ran the same trap in the same place but with a 20W Blacklight bulb.
In total 35 pairs of results were obtained.
A summary of the results is given below.
Total number of moths caught
Mean number of moths per night
Mean number of species per night
Total number of different species caught
Number of species not caught with other bulb
