Thanks very much for the advice MR Magoo.

Looks like the MV it is then. It is just mildly frustrating that I get at 5-10 species per night within a couple of hours of darkness on either the window or in the house yet none in the trap.

I have a close fitting lid that I put on the trap immediately after switching off and removing the light out so they must have been escaping before that.

Although the trap is in my garden I live ruraly and with the exception of neighbours immediately next door the nearest buildings or other light sources in any other direction are all a mile + away so I have used some very bright although non-MV lamps that I have.

I will also try rumaging around on the ground surrunding the trap.

With any luck we shall get some nights without the downpours we have been experiencing lately rain and I can try running a trap all night. I was a bit more concerned with water entering the trap.

I keep the use of the trap down to twice sometimes three times a week.
