North America is home to multiple species of green moths. Some are widely common with widespread presence while others are only found in Southern states.
Green moths come in different sizes. With a minimum wingspan of just 10mm, these colorful moths are also found in species that have a wingspan of more than 50mm.
The green coloring of the moths varies from pale green to dark green. Emerald green moths are also highly common.
The following species of green moths are prevalent in North America.
Table of Contents
1. North American Luna Moth
North American Luna moths (Actias luna) are a common native species of green moths. The species has all-green coloring.
North American Luna moth appears in one brood in Northern states and multiple broods in Southern states.
Light green wings with gray or yellow eyespots are specific to this species.
Long green tails are also seen on the North American Luna moth.
This family of moths is seen on various plant hosts, mainly those with broad green leaves.
The North American Luna caterpillar is also mostly green, similar to the adult moth.
Caterpillars of the species have a green base color with yellow dots and short bristle-like black hairs.
2. Pale Beauty
Pale Beauty moths (Campaea perlata) get their name from their pale green-gray color.
The species has a pale green color which aids them to remain undetected on their host’s trees.
The wingspan is highly variable in Pale Beauty moths. It can measure anywhere between 21 and 50mm.
Pale Beauty moths live in North America in an expansive territory from Alaska to Florida.
The species is mostly found in woodlands where its caterpillars feed on coniferous tree leaves.
Ash, fir, and elm are just a few host trees of the Pale Beauty caterpillar.
Adults may also be seen feeding on nectar such as blueberry nectar.
3. Wavy-lined Emerald
The Wavy-lined Emerald moth (Synchlora aerata) gets its name from the gray-white lines seen across its wings.
Green is the base color of the species. Emerald green is specific to the moth, as the name of the species suggests.
Most common in North America, the moth is not limited to a single host species, like other moths.
It bites the leaves of multiple plants and includes asters, goldenrods, and yarrows.
Part of the Geometridae family of moths and butterflies, the Wavy-lined Emerald is among the first species to be noted in North America.
4. Blackberry Looper Moth
Blackberry Looper moths (Chlorochlamys chloroleucaria) are highly similar to Wavy-lined Emeralds. Both these species have an emerald green color with white or off-white lines and stripes.
The wingspan of the species is reduced compared to other North American native species. Blackberry Looper moths grow to various sizes and never measure more than 23mm.
The Blackberry Looper stands out with short bright stripes across its emerald green body as well.
This species bears the name blackberry but only the larvae of the family are known for eating blackberries.
Adults mostly feed on plants. As the Wavy-lined Emeralds, adult Blackberry Looper moths feed on a wider range of plants.
Asters, ambrosias, and yarrows are among the most common plants these moths consume.
5. Southern Emerald
Southern Emerald moths (Synchlora frondaria) are only found in Southern US territories and further South in Mexico and The Caribbean.
This species of moth has the same emerald green color as the Emerald genus. Its wings show multiple white stripes and lines as well as white veins and short white hairs across the margins.
The species is found in different climates from arid habitats to crops and even suburban areas.
Many Sothern Emerald moths are found around sunflower crops. Sunflowers are the hosts of their caterpillars which feed on the leaves, stems, and roots of sunflowers.
6. Red-fringed Emerald
Red-fringed Emerald moth (Nemoria bistriaria) broods are seen every year. The species has an emerald green color.
White stripes are seen across its wings together with off-white overlays. The margins of the wings are dark red-brown and yellow.
The antennae of the species are mostly yellow.
You can find Red-fringed moths across North America. The area of the US it lives in dictates its broods and especially its flight season.
The season is shorter in the North and longer in the South.
Red-fringed Emerald moths are active from early spring to late October in Southern states.
The species is also seen in the Northern states, but later in the season with a shorter flight period. These moths appear in May and are only active until August here.
7. Green Leuconycta Moth
Green Leuconycta moths (Leuconycta diphteroides) are prevalent in Southern US territories and Eastern US territories.
This species has a green-gray base color with distinct patterns on the wings which makes for easy identification.
Its pale green base color also has gray nuances which means its wings aren’t vivid green.
Black, white, and even pale yellow are secondary colors from the patterns on the wings are made from.
Multiple white lines and marks with black borders are seen across the wings of the species.
The margins of its wings are either pale yellow or off-white to gray.
Its antennae are mostly black with off-white marks.
The most common place to see these moths is around the host plants they lay eggs on. Goldenrods are the main host plants of its caterpillars while asters are another common host.
8. Red-bordered Emerald

Red eyespots are sometimes seen on the body or the wings of the species.
Females of the species can show up to 7 red and white eyespots on the body.
The seasonality of the species depends on the weather. Red-bordered Emeralds in the South are active all year while those in the North are only active until temperatures start to drop in the fall.
9. Green Oak-Slug Moth
Green Oak-Slug moths (Euclea incisa) are mostly small and green. They are mainly known for mimicking techniques that aim to keep them safe from predators.
These moths are known for having green wings with wide brown margins which curl up into a cylindrical shape.
This act is believed to be an act of slug mimicry. The moths try to appear as slugs so that predators move along since slugs have bad taste.
Commonly seen on oaks as caterpillars, members of the species can have a detrimental role through their consumption of tree leaves.
The caterpillar of the species is identified by a base green color with brown central nuances and long hairs that protect it from birds and other predators.
10. Smaller Parasa Moth
Smaller Parasa moths (Parasa chloris) are part of the same mimicking group as Green Oak-Slug moths.

Smaller Paras moths have a base green color with wide brown margins. The head of the species is also green but covered in short hairs.
These moths keep their wings together in a rolled position.
This rolled position doesn’t immediately give away their species as many predators take them for slugs or other species and tend to move along.
As adult Smaller Parasa moths, caterpillar Smaller Parasas are also known to keep predators away. They have irritating hairs predators tend to stay away from.
11. Bicolored Chloraspilates Moth
This species of moths (Numia bicoloraria) gets its name from its dual coloring.
