Butterflies and Moths

Butterflies and moths belong to a group of insects called Lepidoptera. Like all insects, butterflies and moths have a head, thorax, abdomen, two antennae, and six legs. Additionally, moths and butterflies have four wings that are almost always covered by colored scales, and a coiled proboscis for drinking liquids such as flower nectar. There are exceptions to these generalizations; some moths have wingless adults and some primitive moths lack a proboscis.

How many kinds of butterflies and moths exist?
Butterflies and moths are found on all continents except Antarctica, and scientists estimate that there are approximately 12-15,000 species of butterflies and 150-250,000 species of moths. In the United States and Canada, more than 750 species of butterflies and 11,000 species of moths have been recorded. Many species of moths and a few kinds of butterflies are still being discovered.

What kinds of butterflies and moths live in my area?

Collapse1997 Species Report Card: The State of U.S. Plants and Animals (PDF, 32 pp., 505 KB)
Description: How are the nation's plants and animals faring? Which species are at greatest risk and most in need of special care to ensure their survival? Conservation of our natural resources often requires difficult choices, and in an era of limited resources we must have clear priorities that provide answers to questions such as these. The 1997 Species Report Card: The State of U.S. Plants and Animals addresses this need by providing the latest figures on the condition of our species from the scientific databases of NatureServe. Provides data for number of species by conservation status for vertebrates, mammals, birds, reptiles, amphibians, freshwater-fishes, Lepidoptera, decapoda, bivalvia, plants, conifers, angiosperms.
