Moth
Moths are winged insects in the order Lepidoptera, the same order as butterflies.
Moths are winged insects in the order Lepidoptera, the same order as butterflies. They include about 160,000 species worldwide and are usually nocturnal, though some are active by day. Most moth species have larvae called caterpillars that feed on plants, while adult feeding habits vary by species.
Classification and diversity
Moths are insects in the order Lepidoptera. They are a very large group, with roughly 160,000 known species worldwide.
Appearance and differences from butterflies
Moths and butterflies are closely related, but moths are often described as having feathery or threadlike antennae, duller colouring, and more nocturnal habits. These are general patterns, not absolute rules for every species.
Life cycle and diet
Moths undergo complete metamorphosis from egg to larva, pupa, and adult. Caterpillars usually feed on plant material, while adults may feed on nectar, fruit, sap, or not feed at all. Most moth larvae are caterpillars that feed on plants. Adult moth diets vary; many drink nectar, sap, or fruit juices, and some adult moths do not feed at all.
Human relevance
Most moths are harmless, but some species can be household or agricultural pests. A few species may have defensive hairs or other features that can cause irritation or minor harm. Most moths are harmless to people, though some species can be pests in homes, clothing, or stored food.
