A moth...
This moth flies in the daytime. It sips nectar through its long proboscis and even looks like a hummingbird!

What does it look like? edit

Moths have 4 wings with delicate scales that rub off easily. They have a long coiled tube (proboscis) for drinking nectar or tree sap. The proboscis is small or absent in some species. A few species have jaws for eating pollen.

Most moths are night fliers and have dark, dull colors. Those that fly in the day have brighter colors. Moths have different ways of holding their wings. Some hold them like a roof over the body. Others curl them around the body. Antennae sometimes look like combs or feathers.

Yucca Moths are small with a wingspan of 1-3/8 inches or less. Many are black or metallic blue. They are sometimes marked with gold or silver. Others are pure white. They have long threadlike antennae. The wings are covered with tiny hair-like spines under the scales.

This is the moth with the largest wingspan - It is called the White Witch!

Where does it live? edit

Fairy Moths are found throughout North America, at the edges of shady woods. In the northern regions, they can be seen flying April through July.

Yucca Moths live in dry regions wherever yucca plants grow. They are found from New York to the Midwest, south to the Southwest and Mexico. Many caterpillars live inside leaves and feed on leaf tissue. They are called leaf miners, They make tiny lines or spots on leaves. Others spin cases (cocoons) from dark coarse silk. Some make cocoons at the base of the tree. Others wrap up in living leaves. Adults can be seen in flight May through July.

Potato Tuber Moths live in potato fields and storage areas. They are found in the southern and southwestern United States.

Ailanthus Webworm Moths live in meadows of southern New England to Michigan and south to the Gulf of Mexico.

Manroot Borer Moths live in dry open areas. They are found in Kansas and western Texas, in southern California, and north to Oregon.

Spanish Vine Borers live in open areas that are being prepared for raising crops (cultivated). They are found from southern Canada to Mexico, but not on the Pacific Ocean coast.

Doll’s Clearwing Moths live in woods where the trees are not too close together. They live on tree-lined streets and along roads. They are found along the Atlantic coast from Massachusetts to the Appalachian Mountains in Virginia.

California Sycamore Borers live in forests that have California sycamores and oaks trees. They are found from Idaho to California and north to Washington.

Fruit Tree Leaf-Roller Moths are found throughout North America. They are found in forests and orchards living among trees. Their caterpillars live in rolled up leaves held together with silk.

Orange Tortrix Moths live in orchards and in fields where shrubs and plants grow close to the ground. They are found from Wyoming to California and north to Canada.

Codling Moths are found throughout North America in fruit orchards, especially apple and pear trees.

What does it eat? edit

Fairy Moth caterpillars feed on flowers or seeds of milkweed and other plants. As they grow they feed on foliage.

Yucca Moths eat foliage and seeds. Their caterpillars eat yucca plant seeds. Without moths, yucca plants cannot reproduce by pollination. They have to reproduce by root offshoots instead. Fewer new yucca plants grow by offshoots.

Clothes Moth caterpillars have moveable cases and live near a food source. They feed on leaves, fungus, vegetable fibers, and hair. Adults are short-lived and do not feed. Bagworm Moths spin a cocoon to carry around while feeding.

Gelechiid Moth caterpillars include leaf miners, gall makers, and seed eaters. Leaf miner larvae live inside plant leaves. Leaf miners make little lines in the leaf. Gall makers cause little bumps on leaves, stems, flowers, and roots. Galls appear in many shapes and sizes.

Potato Tuber caterpillars feed on leaves, stems, and potatoes. Ermine Moth caterpillars eat leaves or bore into fruit. Spanish Vine Borer caterpillars eat gourds, squash, pumpkin, cucumber, and musk-melon.

Clear Winged Moth caterpillars make holes on stems, roots, and bark of trees and other plants. Dolls Clearwing Moth caterpillars bore into willow and poplar trees. California Sycamore-Borer caterpillars usually eat older, living trees.

Fruit Tree Leaf-Roller caterpillars eat leaves of apple, pear, quince, and walnut trees. Orange Tortrix caterpillars feed on buds, leaves, and blossoms of fruit trees and shrubs. Codling Moth caterpillars feed on fruit.


 
The larvae of this moth eats clothing.

How does it defend itself? edit

Some species of moths make a clicking sound to defend against bats. The clicking sound disrupts echolocation signals that bats use to find prey.

Fruit Tree Leaf-Roller caterpillars use silk threads to drop to the ground when threatened. They use the same threads to return to their nests after danger passes.

The Wood Tiger Moth has bright colors to warn predators. This moth has two kinds of defenses. One is a very bad smell to keep birds away. The second is a toxic fluid that defends against insects.

What stages of metamorphosis does it go through? edit

Bagworm Moth females lay eggs in a cocoon to protect the caterpillars.

Gelechiid Moth females lay 150 to 300 eggs on leaves, stems, or exposed tubers (fleshy outgrowths). The caterpillars spin silken cocoons.

California Sycamore-Borer females lay eggs in bark crevices. Caterpillars hatch in a few days and bore into the bark. They make tunnels where they over-winter and mature.

Fruit Tree Leaf-Roller females lay their eggs in tree trunks or branches. They cover them with a kind of cement. The eggs hatch in the spring. They grow in rolled-up leaves.

Orange Tortrix females lay masses of pale-yellow eggs on twigs and branches. Caterpillars make nests among twig tips, where they overwinter and grow.

What special behavior does it exhibit? edit

Fruit Tree Leaf-Roller caterpillars make silk threads to drop to the ground when danger threatens. ok

A Leaf-Roller caterpillar makes silk threads to wrap up a leaf and make a protective covering. ok

Yucca Moth females make a sticky ball from yucca flower pollen. They carry the ball to a different yucca flower to lay their eggs. This cross-pollinates the plant so many flowers will bloom. It also makes food for the caterpillars. ok

How does this bug affect people? edit

Adult flying moths do not damage clothing. Clothes Moth larvae make holes in clothes made from wool, silk, and other fibers.

Pantry Moths are also called Indian Meal Moths. They eat flour, bird seed, pet food, cereal and other grains.

Most Gall-making moths do not damage host plants. Galls are often used in flower arrangements and crafts.
