Moths are among the most diverse and successful organisms on earth.
Scientists estimate there are 150,000 to more than 500,000 moth species.
Their colours and patterns are either dazzling or so cryptic that they define camouflage. Shapes and sizes span the gamut from as small as a pinhead to as large as an adult’s hand.
Most moths are nocturnal, and need to be sought at night to be seen – others fly like butterflies during the day.

National Moth Week celebrates the beauty, life cycles, and habitats of moths. “Moth-ers” of all ages and abilities are encouraged to learn about, observe, and document moths in their backyards, parks, and neighborhoods.
