They are fascinating creatures ; I ran a moth trap in my garden for some years, but now the residents in the small development where I live ( just 6 houses) have all voted to keep the garden lighting on all night - as a security measure - not that there has ever been a single incident of problem in the 7 years it has existed - but the average age of residents is about 80 +.. so maybe they are all a bit more nervous than I am as a young 79 and 3/4 ....) and my moth trap is not worth running. I did go to one of the nature reserves on the other side of the county for a time, but the 25 mile journey through the rush hour in the morning took too at least an hour and a half, so I gave up. In UK we divide the moths into the macro - the bigger ones - maybe 600 species , and the micro - 2000 species , and it is usual to concentrate only on the macro until you are very very good ... I never got that good, but we have some lovely species in the macro. My favourite are the elephant hawks - before we had those pesky lights on all night, in the right season, I would get a moth trap full of them - mabe 40 or more - they would perch on my finger whilst I took their pictures.
