Gypsy Moth Pictures,

What do Gypsy Moths look like?

Gypsy Moth Caterpillars do damage trees.

Lymantria dispar dispar, commonly known as the gypsy moth.

European gypsy moth, or North American gypsy moth, is a moth in the family Erebidae that is of Eurasian origin. It has a range which covers Europe, Africa, and North America.

Carl Linnaeus first described the species Lymantria dispar in 1758. The subject of classification has changed throughout the years, resulting in confusion surrounding the species' taxonomy. This caused many references to describe this one species in different ways. The family has jumped between Lymantriidae, Noctuidae and Erebidae. Lymantria dispar dispar has been designated a sub-species of Lymantria dispar.

It is classified as a pest, and its larvae consume the leaves of over 500 species of trees, shrubs and plants. The gypsy moth is one of the most destructive pests of hardwood trees in the eastern United States.

Introduction to North America.

Gypsy moths in the United States

Progressive spread of the gypsy moth (L. dispar) across north east US from 1900–2007; compiled from county data by US Forest Service

The gypsy moth was introduced into North America in 1869 from Europe.

Étienne Léopold Trouvelot imported the moths, with the intent of interbreeding gypsy moths with silk worms to develop a silkworm industry.

The moths were accidentally released from his residence in Medford, Massachusetts.

There are conflicting reports on the resulting actions. One states that despite issuing oral and written warnings of possible consequences, no officials were willing to assist in searching out and destroying the moths. The other notes that he was aware of the risk and there is no direct evidence that he contacted government officials.

As noted in The Gypsy Moth (1896) by Forbush and Fernald, the gypsy moth was considered a nuisance just ten years after their release.

The first major outbreak occurred in 1889, and Forbush and Fernald recount the extent of devastation: all the trees being defoliated and caterpillars covering houses and sidewalks and raining down upon residents.

At first it was uncertain what species was responsible for the outbreak, but after the caterpillar was identified by entomologist Maria Elizabeth Fernald, an eradication program began in 1890.


The small larvae of the gypsy moth take to the air and are carried by the wind.

The larvae spin silken threads and hang from them, waiting for the wind to blow.

The light larvae have long hairs that increase their surface area, which are suitable for being carried aloft.

The natural spread is slow, but transportation of the moth has led to isolated gypsy moth populations, with accidental transport of the eggs being noted.

According to the United States Department of Agriculture, without intervention, this pest spreads about 13 miles per year

Typically, short distances can be traversed by larva, but there is suspicion that long distance flights are possible. It has been hypothesized that storms carried the larva across Lake Michigan to the western shore, a span of dozens of miles.


Gypsy moth caterpillar

Larvae (caterpillars) emerge from egg masses in the spring. Most larvae hatch within a week, but it could take as long as a month.

The new larvae remain on or near the egg cluster if they hatch in rainy weather or if the temperature is below 7C

The larva will disperse even if there is enough foliage for growth, they hang from silk threads and wait for the wind to send them aloft. The larva are about 3 mm when they first hatch and will grow to 50 or 90 mm in size.

The larva will first feed on the leaf hairs and then move onto the leaf epidermis.

Feeding occurs in the daytime, primarily in the morning and late afternoon As the larva grow, the feeding becomes a nocturnal activity.

When not eating, the larva will remain on the underside of the leaf and make a mat of silk for attachment.

To grow, the larva must molt.

Larva are characterized by the term 'instar', which refers to the number of times a larva has molted; a first-instar has not yet molted, a second-instar has molted once, a third-instar has molted twice, etc.

Males typically are five instars and females are six instars

When the larvae reach the fourth instar, they become nocturnal feeders, and will return to their resting places at dawn, hiding under flaps of bark, in crevices, or under branches - any place that provides protection.

Newly hatched larvae are black with long, hair-like setae. Older larvae have five pairs of raised blue spots and six pairs of raised brick-red spots along their backs, and a sprinkling of setae.

As the larval stage comes to an end they cease feeding and surround themselves in a silken net


The gypsy moth brings one of the largest impacts in defoliation of deciduous trees in the Northern Hemisphere. Since its introduction in to the United States in 1868 or 1869, it has spread both West and South, now taking over most of the hardwood forests in the eastern United States and Canada

Over three hundred species of trees and shrubs are host to the gypsy moth.

Gypsy moth larvae prefer oak trees, but may feed on many species of trees and shrubs, both hardwood and conifer.

In the eastern US, the gypsy moth prefers oaks, aspen, apple, sweetgum, speckled alder, basswood, gray, paper birch, poplar, willow, and hawthorns, among other species.

Older larvae feed on several species of softwood that younger larvae avoid, including cottonwood, hemlock, Atlantic white cypress, and pine and spruce species native to the east.

The gypsy moth avoids ash trees, tulip-tree,

American sycamore, butternut, black walnut, catalpa, flowering dogwood, balsam fir, cedar, American holly, and mountain laurel and rhododendron shrubs,

but will feed on these in late instars when densities are extremely high.

Larvae will climb up any object in their path in search of food, including telephone poles, vehicles, even people.


The males have feathery antennae versus the thin antennae of females.[2]:11 Size differences are also noted, with the forewing of the male moth being 20–24 mm long, and that of the female 31–35 mm.]

Obviously, from this it is noticeable that the females are bigger than the males. Another important difference between the sexes is that females possess fully formed wings, but do not fly.

Female flight is common in Eurasia and Asia, but these moths may be of a different species.

The other species is called the Asian Gypsy Moth.

Moths usually emerge from pupae in July, but it can vary with population density and climate. The brown male gypsy moth emerges first, usually one or two days before the females do.

The males fly in rapid zigzag patterns, but are capable of direct flight. Like most moths, the males are typically nocturnal, but can sometimes be seen flying during the day as well. The males fly up and down tree trunks, or other vertical objects in search of females.

When heavy, black-and-white egg-laden females emerge, emitting a pheromone that attracts the males

The female has a small gland near the tip of the abdomen which releases the pheromone, with a pumping motion, termed 'calling'. It can attract males from long distances, tracking the scent through its erratic flight pattern.

Courtship is not elaborate; the female must raise her wing to allow the male to couple with her.T

The moths remain in copula for up to an hour, but the transfer of the spermatophore is usually accomplished within 10 minutes.

Male moths can inseminate more than one female Multiple mating in females is possible, but uncommon, because the female stops releasing the attracting pheromone after mating.

After mating, the females begin depositing the eggs.

The adult moths live about one week.They do not possess an active digestive system and cannot feed, but can drink in moisture.

The reproductive chance for females lasts about two days, with the pheromone for attracting males being diminished by the third day.

Due to the pheromone's potency, most females will mate.

The females also produce offspring after they mate with a male, laying eggs on trees, shrubs, rocks, vehicles, and plants of many types. She typically lays about 500+ eggs.

The eggs are covered with a peachy fuzz that can cause serious rashes if they are touched by bare skin or fur, especially on humans and mammals. Then the female leaves to eat, while her eggs are protected. She does not live to see her offspring.
