Luna Moth Caterpillar

  • The size of an adult human hand’s palm, these enormous, shapely moths are a delicate green color with eye-shaped patterns on their hindwings and small crescent-shaped loops on their forewings.
  • Caterpillars of the Luna moth are lime green in color with magenta patches and scanty hairs, as well as a faint stripe running lengthwise right below the spiracles.

Luna Moth Meaning

  • Luna is a Latin word that means “moon” and refers to the moon-like eyespots on its wings.
  • Moon moths, or American moon moths, are other names for them.
  • The name is doubly appropriate because these night-flying moths are most active when the moon is high in the sky.

  • With a wingspan of 3 to 4 inches, Luna moths are among the largest moth species in North America.

Food & Diet

  • Caterpillars of the Luna moth consume the leaves of walnuts, hickories, pecans, persimmons, sweet gums, and sumacs.
  • Adults, like other members of the gigantic silkworm family, have reduced mouthparts and do not consume any food.
  • Adults only survive for roughly a week as a result.


  • It is active at night and sleeps during the day.
  • Its wing coloring helps them in hiding. If a Luna Moth is about to be assaulted, it will rear up, make clicking noises, and spit a foul-tasting substance to defend itself.
  • They have a nighttime method for avoiding bat capture. Bats’ echolocation hunting mechanism is confused by the lengthy twisted hind wings, according to scientists.


  • They are exclusively found in North America and can be found as far north as Nova Scotia, as far south as southern Florida, west as Saskatchewan, and as far east as the Gulf Coast of eastern Texas.
  • They like deciduous hardwood woods to live in. 


  • Typically found in wooded places.
  • It can be found from Nova Scotia to Saskatchewan in southern Canada.
  • It can be found in every eastern state in the United States, from Maine to Florida, and west to eastern Texas and eastern North Dakota.

Luna Moth Life Cycle

  • Male Luna Moth are attracted to female Luna Moths because they emit perfume (a chemical compound).
  • Mating is usually done after midnight.
  • The eggs are laid in small clusters on the leaves of the host plants throughout the next few nights.
  • The eggs hatch into tiny, hungry caterpillars in a week, and they’ll molt five times before wrapping themselves in a papery cocoon.
  • The adult Luna Moth emerges from the pupa after three weeks, generally in the morning so that the sun can dry their wings before their maiden flight.
  • Northern moths only reproduce once a year, in June. Southern moths can breed twice or three times a year.

Predators & Parasites

  • They are eaten by owls, bats, bald-face hornets, parasitic wasps, and flaming searcher ground beetles, to name a few predators.
  • Luna moths, particularly large larvae and adults, are prized by insectivores.
  • As a result, luna moths have evolved amazing defenses against predators.
  • The caterpillars have a pale green tint, similar to the foliage they eat.


  • The defense mechanisms of this creature are fascinating.
  • Their distinctive eyespots are thought to have evolved as a defense strategy, and they are known to make a sharp clicking sound by rubbing their mandibles together when attacked.

Purple Luna Moth

  • It is only found in North America.
  • Their long, thin tails extend from their vivid green wings.
  • The presence of a purple or pink ‘bumper’ at the front borders of the wings is difficult to overlook.
    The forewings necessarily have had a downy coating.
  • Their wings have four distinct eyespots, and their antennae are highly fluffy.


  • It represents a never-ending search for truth and knowledge, as well as the gift of intuition, psychic perception, and heightened awareness. Matters about “seeing the light.”

Luna Moth Caterpillar Poisonous

  • They are quite harmless.
  • They are not poisonous.
  • Because of their brilliant colors and hairy body, they could be mistaken as harmful.

Host Plants

  • Host plants are the plants on which an organism feeds and survives.
  • Consider the pickiest eater you’ve ever met.
  • Even if they don’t appreciate a large variety of foods, they are likely to eat more than one.
  • Imagine being able to eat only one type of food.
  • That’s how insects that have a specific host plant feel! The best example of a Host plant is Milkweed. 

Luna Moth Tattoo

  • Luna Moth are supposed to be symbols of endless repetition and are spiritually tied to the moon.
  • It symbolizes tenacity in the face of hardship, adaptation, determination, and success, all of which are derived from this interesting transmutation process.
