The order Lepidoptera includes all butterflies, moths, and skippers, distinguished by their scaled wings (lepis = scale, ptera = wings), coiled proboscis, and complete metamorphosis. Lepidoptera are found worldwide, with about 180,000 described species. Their life cycle includes egg, larva (caterpillar), pupa (chrysalis or cocoon), and adult stages, allowing them to exploit different ecological niches and contributing to their diversity and success.
- Scaled wings are unique to Lepidoptera, providing color and pattern for camouflage, warning, and mating.
- Larvae are important herbivores, while adults are pollinators and prey for many animals.
- Major groups include butterflies (Rhopalocera), skippers (Hesperiidae), and moths (various families).
Wing scales are the distinctive feature of Lepidoptera.

Lepidoptera Families
- Papilionidae: Swallowtail butterflies, known for large, colorful wings and tail-like extensions; classic butterfly form.
- Hesperiidae: Skippers, with robust bodies, hooked antennae, and rapid, darting flight; intermediate between butterflies and moths.
- Noctuidae: Owlet moths, mostly nocturnal, with dull forewings and sometimes striking hindwing patterns; one of the largest moth families.
- Nymphalidae: Brush-footed butterflies, with reduced forelegs and diverse, often striking wing patterns.
- Sphingidae: Hawk moths, with streamlined bodies and powerful flying ability; some species hover like hummingbirds.
Skippers are members of the family Hesperiidae.
Noctuidae moths are mostly nocturnal.

Examples of Butterflies: Papilionidae
The Papilionidae family includes the swallowtail butterflies, recognized for their large, colorful wings and distinctive "tail" extensions on the hindwings that resemble a swallow's tail (in many species). These butterflies exhibit close-to-perfect wing symmetry and vibrant patterns, often including yellows, blues, and blacks. They are mostly diurnal and are found worldwide, with a preference for warm climates.
- Larvae commonly feed on parsley, fennel, and other members of the carrot family.
- Adults are strong fliers and frequent nectar sources such as flowers, often seen in gardens and meadows.
Papilionidae caterpillars primarily feed on plants in the carrot family.
Papilionidae are most diverse in tropical regions.

Examples of Moths: Noctuidae
Noctuidae, or owlet moths, constitute one of the largest and most diverse moth families. Most are nocturnal, with adults typically sporting dull, camouflaged forewings and more colorful hindwings hidden at rest. Caterpillars of many species are major agricultural pests (cutworms, armyworms), feeding on a wide variety of crops.
- Adult moths are attracted to light (positive phototaxis).
- The family includes some species capable of rapid population increases, causing defoliation.
Adults of Noctuidae are known for being attracted to light.
Noctuidae caterpillars are considered pests due to crop damage.

Examples of Skippers: Hesperiidae
Hesperiidae, or skippers, bridge the gap between butterflies and moths. They have stout, furry bodies, hooked antennae, and exhibit a characteristic rapid, darting flight—hence their name. Their wing structure is more rigid than typical butterflies, aiding in their swift movements. Most skippers are diurnal and favor open habitats like meadows and grasslands.
- They often boast muted colors like browns, grays, or oranges.
- Larvae usually feed on grasses and sedges.
Hesperiidae skippers have uniquely hooked antennae.
Hesperiidae larvae preferentially feed on grasses.
