The Reading / Listening - Light and Insects - Level 6

Everyone knows that light attracts insects. In prehistoric times, our ancestors questioned why winged insects buzzed around fire. An old saying describes this attraction as being, "like a moth to a flame". However, a recent study dispels the long-believed notion that insects head towards light because they like it. Biologists at Imperial College London have reported that insects are drawn to light because it helps with their orientation when in flight. The scientists said artificial light actually disorients nocturnal bugs like moths and mosquitos, often to fatal ends. Jamie Theobald, co-author of the study, said all our speculations about why insects fly toward light "might have been wrong".

The scientists conducted their research in a rainforest in Costa Rica. They installed artificial lights under the canopy and observed the creatures' flying behaviour. Insects usually navigate by the moon to fly in straight lines. However, around the artificial lights, the bugs became confused and made arcs and erratic patterns of flight. An entomologist said: "Natural sky light…helps maintain proper flight….Artificial sources…can produce continuous steering around the light and trap an insect." This explains why so many insects fly to their death into bug zappers. Artificial light adversely affects an insect's ability to find a mate, forage for food, and defend itself against predators.

However, a recent study dispels / spells the long-believed notion that insects head / back towards light because they like it.

    everyone knows that light attracts insects in prehistoric times our ancestors questioned why winged insects buzzed around fire an old saying describes this attraction as being like a moth to a flame however a recent study dispels the longbelieved notion that insects head towards light because they like it biologists at imperial college london have reported that insects are drawn to light because it helps with their orientation when in flight the scientists said artificial light actually disorients nocturnal bugs like moths and mosquitos often to fatal ends jamie theobald coauthor of the study said all our speculations about why insects fly toward light might have been wrong

    the scientists conducted their research in a rainforest in costa rica they installed artificial lights under the canopy and observed the creatures flying behaviour insects usually navigate by the moon to fly in straight lines however around the artificial lights the bugs became confused and made arcs and erratic patterns of flight an entomologist said natural sky lighthelps maintain proper flightartificial sourcescan produce continuous steering around the light and trap an insect this explains why so many insects fly to their death into bug zappers artificial light adversely affects an insects ability to find a mate forage for food and defend itself against predators
