“Like moths to a flame” is a saying that alludes to insects’ apparent attraction to artificial light. A new study has found a potential explanation for the behavior.
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
A simple light trap A more complex moth trap. Entomologists primarily use light-based moth traps, which exploit the phototactic behavior of moths, attracting them to a light source. Moths navigate by using natural light sources such as the moon and stars, and artificial light sources can confuse and draw them in.
These flights take place during the twilight hours during which blue light (400–475 nm) rather than UV light (10–400 nm) is dominant and attracts the moths. Blue light's role in the Indian-meal moth foraging behavior has recently been harnessed as a form of pest control since it is attractive to the moth. [13]
Butterflies and moths can see ultraviolet (UV) light and wing colors and patterns are principally observed by Lepidoptera in these wavelengths of light. [13] The patterns seen on their wing under UV light differ considerably from those seen in normal light. The UV patterns act as visual cues that help differentiate between species for mating.
The moths have lived in Europe and Asia for thousands of years but were accidentally introduced to Boston in the 1860s. Spongy moths feed on foliage of many plant varieties but prefer oak trees.
The colour was a perfect camouflage on light-coloured trees covered with lichens. The new form, carbonaria, was completely black. There was an intermediate form, called insularia, which was light-coloured with speckled wings, but distinct from typica in that it was not whitish. The moths were active at night, and rested on tree trunks and ...
