Finding moths

Observing moths is very easy; you don’t even have to actively look for them. By using two simple methods to attract moths, all you have to do is wait for them to come to you. Moths are attracted to light (no one really knows why although there are a number of theories), and also to the smell of fermented sugar and ripe fruit – both food sources.

Light set up for beginners

  1. Any type of light will attract moths. Just leave a porch light on and wait and see what is attracted to it. If you are in a field or forest, you can use battery-operated lights or even a flashlight. Entomologists use black lights and mercury vapor lights, which emit light in a color spectrum that moths find irresistible. These types of lights can be ordered online at relatively low cost.
  2. Moths need a surface to rest on. White sheets are often used. Hang a sheet over clothes line or between two trees, and shine the light on it. An outside wall also works well if your light is set up near a house or a building.
  3. Wait for the moths to come to your light so you can observe and photograph them.
——Specialty lights and light traps can be purchased from entomological equipment suppliers such as BioQuip (Tel: 310-667-8800). Mercury Vapor and black lights can also be purchased from hardware stores or ordered online. Blacklights can also be found in Party stores. ——

moth sugaringSugaring for moths

  1. Moths can smell food from a distance. When provided with fermented sugar and fruit, they will fly right to it. This method of attracting moth is simply called ‘sugaring’.
  2. Make “moth food A mix of sugar, fruit (banana, peach or other overripe fruit) and beer will work. Try Dave’s not-so-secret recipe or experiment with your own recipe.
  3. Brush the mix on tree trunks an hour before dusk.
  4. Check every 30 minutes to see what’s coming to the bait.
