• There are many species of insects that look like leaves, including leafhoppers, katydids, orange oakleaf butterflies, dead-leaf moths, leaf insects, and dead-leaf grasshoppers. 

• Some of these leaf bugs resemble the appearance of leaves and their behavior by mimicking the movement of a blowing leaf.

1. Leafhoppers (Cicadellidae)

Leafhoppers are tiny green leaf bugs that seemingly defy gravity with incredible jumps. Some species of grasshoppers boast vibrant hues and have striking striped patterns, while others have mastered the art of camouflage, seamlessly blending with the color of their host plant. 

Usually, these bugs are in green, brown, yellow, and mixed colors. However, many tiny green bugs that look like leafhoppers but aren’t. So, don’t get them mixed up.

Leafhoppers go through three stages of development: egg, nymph, and adult. This is when they gain their characteristic leaf-like appearance. This green bug that looks like a leaf doesn’t munch on leaves; instead, they feed on the saps of plants. Additionally, most of these bugs are 2 to 30 mm long. And up to this point, about 23,000 different species of leafhoppers have been identified, and more are being found daily.

2. Katydids (Tettigoniidae)

Katydids, also known as bush crickets and long-horned grasshoppers, are another species of green bug that looks like a leaf. They also come in other colors, such as brown, yellow, and oh-so-rare pink. You can tell a katydid from other insects by the position of its wings, which are held over its body vertically, like a roof of a house.

These bugs also boast thin, long antennae larger than its body. There are around 6,400 species of katydids in the world. While most species of katydids feed on leaves and flowers, there are ones that like to eat other insects or eggs.

3. Orange Oakleaf Butterfly (Kallima inches)

The orange oakleaf butterfly, also known as the Indian oakleaf butterfly and dead leaf butterfly, is an insect that looks like fallen leaves. What makes them unique is that they mimic the color of fallen leaves and their shape and veins. They also can change their looks according to the season.

These fluttering butterflies can be found in the forests of tropical Asian countries such as India, Laos, Vietnam, and Taiwan. Adult orange oakleaf adult butterflies mainly eat tree sap and rotting fruits. 

4. Dead-Leaf Moths (Uropyia meticulodina)

Another insect that looks like a leaf is a Dead-leaf moth. However, these moths don’t look like fresh green leaves; instead, they look like brown dead leaves, hence the name. These moths’ exceptional dead and curled leaf camouflage enables them to blend in with dead leaves, helping them to evade predators. 

Because of their brown color, you may confuse them with other brown insects. But unlike other bugs, Dead-leaf moths have wings 2 1/4 – 3 1/16 inches long.

5. The Leaf Insect (Phylliidae)

The leaf insect is a green-colored bug that looks and acts like a leaf. When a leaf insect walks, it mimics the movement of a leaf being blown with the wind by rocking its body back and forth. For this, it is also known as the “walking leaf.”

These leaf-like bugs range in length from 1.1 to 3.9 inches. And they usually eat leaves, fruits, and flowers such as blackberries and roses. They also do not bite or sting, so rest assured that you can observe them without fear.

6. Dead-leaf Grasshoppers (Chorotypus sp.)

Dead-leaf grasshoppers are a species of grasshoppers that are native to Malaysia. You can find this insect in the woodlands, meadows, and marshes. But as this bug looks like a leaf, a dead one at that, it can be quite hard to spot one. Additionally, these grasshoppers like to munch on leaves, flowers, and fruits.
