The moth is a polyphyletic insect group that contains all members of the order Lepidoptera. The fungus moth (Tineidae) and the webbing clothes moth (Tineidae) are common North American moths.

Moths differ from butterflies in various ways. Moths sleep open-winged, while butterflies sleep closed-winged. In contrast to moths, butterflies have long and slender antennae. Butterflies feed in the day while moths are nocturnal, mostly.

Moths help the ecosystem. They pollinate flowers and produce seeds, yet sadly, moths provide food for many insects, frogs, birds, bats, and other creatures.

A Moth’s Life-Span

The habitats of moths are varied. They are found in marshes, gardens, dunes, and mountain peaks; therefore, their life cycle is surprising. The embryonic stage of a moth’s life cycle occurs inside the female’s eggs.

To provide sustenance for the larvae, the female looks for a place to lay eggs. After laying 50 eggs in two weeks, a female dies. (Read Can Dogs Eat Mint Leaves)

The larval or caterpillar stage is the second stage of moth development. Its protein- and the nutrient-rich shell is the first thing they eat when they emerge from it. It eats 2,700 times its weight throughout this time.

The third cycle is the pupal stage which follows the larval stage. Caterpillar pupae become adult moths within a cocoon at this stage. The pupa stage is also called a chrysalis, and the larvae use all the food they eat to convert at this stage.

The moth then enters the imaginal stage, which lasts about a week, where adult moths emerge from their cocoons.

If you ask, do moths eat clothes? You might encounter a few different species nibbling on the natural fibers found in woolen garments and soft cashmere. Two such species are Tineola bisselliella, or clothes moths, and Tinea pellionella, or case-making clothes moths.

Adult moths lack the mouthparts required to consume lint from your clothing. Instead, the moth larvae’s voracious hunger is performing the feeding, where the textile pests chewing organs can eat through anything.

A Cherry Dagger species of moth, for example, will eat only cherry trees, and The Common Oak Moth eats oak trees.

Harvester butterfly adults may puncture the bodies of woolly aphids with their short proboscis (tongue) and consume their juices.

Moths will devour pet fur or chew through synthetic materials to burrow into natural fibers underlying if they run out of clothing fibers.

The larvae hatch in four to ten days, depending on the temperature. Warm temperatures promote faster hatching, whereas cool conditions slow or prohibit hatching.

Depending on the food source and temperature, larvae can live anywhere from 35 days to two and a half years. They can do a lot of damage to materials during that period. (Read Do Deer Eat Pepper Plants)

The larvae weave a web (webbing moths) or a case (casemaking moths) around themselves as protection and disguise as they emerge.
