What do you know? After sending the MV out into the garden to reignite the 'Warren Road Back Garden Moth Year List', and being successful with a Spring Usher, the past two nights trapping have produced... bugger all! Both nights have been very mild, mostly cloudy and I have even inspected the trap in the wee small hours dressed but in my jimjams - and not felt even chilly. I'm not being greedy, a Chestnut would have done!
So, how do I break this blank spell? Make a sacrifice to the Moth Gods? Should I just accept that in suburbia at this time of year a blank night is the norm? Change the bulb? Ah, that jogs a memory. I seem to remember reading somewhere that you should change your MV bulb every season as it loses some of its ability to function at 100%. Is that something that the bulb manufacturers invented to ensure that we buy them more frequently? Whatever the truth is, I will replace the bulb tonight that is, admittedly, at least into its third year.
There is no doubt that those MVs operating in woodland at this time of year are the ones that are going to catch higher numbers. One chilly December night I drove from Brighton back to north Surrey and was amazed at the number of moths that the car headlights picked up as I drove through the countryside, particularly well wooded areas. Literally hundreds of them. I put the MV out in the garden as soon as I got home, even though it was quite cold, convinced by my drive home that I would be successful. The next morning the trap was empty.
