Some moths are leaf miners.

1 Attraction to light

Moths are notable for apparently being attracted to light, or more specifically, are known to circle ambient objects. The reason for this behaviour is not known. Moths do not fly directly away from the light due to a visual distortion called a Mach band. One researcher, Henry Hsiao, has conjectured that moths, as nocturnal creatures, fly towards the darkest part of the sky in pursuit of safety. Moths are thus inclined to circle ambient objects in the Mach band region, usually at a radius of about one foot, depending on the species.

Night blooming flowers usually depend on moths (or bats) for pollination, and artificial lighting can draw moths away from the flowers, impacting the plant's ability to reproduce. Light pollution is coming under increasing scrutiny as a source of many subtle ecological changes.

Moths of the type understood to be "attracted to light" are, instead, flummoxed by the proliferation of artificial lights in their local environment, which, if brighter than the brightest celestial object (e.g., the moon), will usurp that object's significance as the reference point for the moth's flight. To travel in a straight line, a moth would maintain the same angular relationship with the (relatively stationary) moon. Encountering a brighter artificial light, as the moth maintains its angular relationship to the source of light (per its evolved mode of navigating), but, because the light is nearby, that consistent angle results in a decreasing spiral, until the moth strikes the light source.

2 Moths as pests

Moths are commonly regarded as pests because the larvae of a few species eat fabricSee cloth Fabric is also the name of a London dance club. such as clothes and blanketquilt is one type of blanket. A blanket is a (usually square- or rectangular-shaped) piece of cloth, generally intended to keep people warm, especially while they sleep. It can be distinguished from sheets by its thickness and its intention; the thickests made from natural fibres such as wool. They are less likely to eat mixed materials containing artificial fibres.

There are some reports that can be repelled by the scent of wood from juniper50-55 species; see text. Junipers are coniferous plants in the genus Juniperus of the cypress family Cupressaceae. There are about 50-55 species of juniper, widely distributed throughout the northern hemisphere, from the arctic, south to tropical Africa i and cedarCedrus deodara ''Cedrus libani C. libani var. libani C. libani var. stenocoma C. libani var. brevifolia C. libani var. atlantica Cedar correctly refers to those trees belonging to the genus Cedrus in the coniferous plant family Pinaceae. They are most clo, by lavender or by other natural oils. However, many consider this unlikely to prevent infestation. NaphthaleneNaphthalene (also known as naphthalin, naphthaline, tar camphor, white tar, albocarbon, or naphthene) is a crystalline white solid hydrocarbon, with the empirical formula C H. It is volatile, forming a flammable vapor. Its molecules consist of two benzene (the chemical used in mothballMothballs are small balls of chemical pesticide and deodorant used when storing clothing and other articles susceptible to damage from mold or moth larvae. They come in two different formulations, one using naphthalene and the other using paradichlorobenzs) is considered more effective, but there are concerns over its effects on health. Freezing items infested with moth larvae will not kill them. An effective way of disposing of moths without the use of chemicals is to use Electric Fly Traps
