UV light traps - how far above the ground?

[Jean-Michel MAES]

Why not try different positions.
For scarab we put the light trap on the ground, for leps we put them at 2 m
high but I see in the city that the lights at 4 or 5 meter high works also
very well. What I was thinking to do is put one light very high (5 to 10
meters high), then 3 or 4 lights at 2 meters hight. I guess the very high
one could attract far but is not very easy to catch the moths.
