Moth evening, held down the track May 2003
This was a great place as there was an abundance of different types of trees under which the detectors could be placed. The lights are about 150 watts and give off a high UV light source, so it is best not to look at them directly. The lights are powered by small portable generators, and left on for about 2 hours. Overnight is better, but you tend to get 80% of what you will get in a couple of hours

On a temporary basis the moths may be put in a tube for closer examination. All the moths are released at the end of the session |
