The composition of butterflies and stick insects is 400 words.
Stick insects move slowly, squatting on branches during the day and eating leaves at night. Its reproduction is also very special. Generally, eggs are laid on branches after mating, and it takes one or two years for larvae to hatch. Some females can lay eggs without mating and give birth to offspring without fathers. This phenomenon is called parthenogenesis. Stick insects are incomplete abnormal insects, and newly hatched nymphs are very similar to adults. They often climb trees at night, shed their skin several times and gradually grow into adults. Adult life span is very short, only about 3 ~ 6 months.

Stick insects are very active at night and just stay quietly during the day. Because they look like twigs, they are generally not found by the enemy. Stick insects are so cleverly disguised that they can only be found when they crawl. When it flies when it is violated, the sudden flashing color light will confuse the enemy. But this kind of colored light only flashed by, and suddenly disappeared when the bamboo leaf insect touched the ground and folded its wings. This is called "flashing color method", which is a method used by many insects to escape.

The insect perches on bamboo and other plants at rest, which is mimicry and protective, and is often difficult to be found. Men are more active,

Exercise during the day and at night, and generally eat more at night. The ventral ends of nymphs and adults bend upward, and when disturbed, they often retreat and fall down, and emit smelly liquid from the front corner of the chest and the back plate. Sexual reproduction, scattered eggs, attached to branches or laying eggs directly, hatch on the surface the next spring, and some species can parthenogenesis.

The eggs laid by stick insects are very large and look like seeds, sometimes even like the seeds of trees or shrubs eaten by bamboo leaf insects. A North American stick insect lays so many eggs that the sound of laying eggs is like the sound of rain.

Dead-leaf butterflies usually live in wooded mountainous areas and often haunt the dense mixed forests under the cliffs. When the male butterfly is active, it often flies on the leaves of broad-leaved trees more than 2 meters above the flowing water of the stream, waiting for the female butterfly to fly over and chase after mating. At this time, throwing the net and catching it is very successful. If the net immediately flies into the jungle and stops on vines or branches, it will fly fast and move fast, and be covered by cool dead leaves in its wings, so it is extremely difficult to find its habitat for a while. Its perching posture is low head and tail, and it often perches on a thick leafless trunk. This species is widely distributed in middle and low altitude mountainous areas, and its common mimicry is dead leaves. Male butterflies have a strong sense of territory and like to stop at high places to drive away butterflies that invade the territory. Adults appear in May-August, and like to suck tree juice and rotten fruit. [2]

Dead-leaf butterflies like to live in cliffs and lush forests and perch on broad leaves on both sides of streams. When the sun rises and the dew on the leaves disappears, it moves to the wound of the low trunk. Once frightened, it immediately flies away with agile movements, escapes to the top of a tall tree or hides on a vine deep in the tree, and hides by imitating the instinct of dead leaves.

Deciduous butterfly (a famous dish in China)

Get up, it's hard to find. After noon, the summer heat recedes slightly, which is a good time for the male butterfly to chase the female butterfly for mating. Dead-leaf butterfly is a rare species in China and a typical mimicry among butterflies. Very few, distributed above 900 meters above sea level. The larvae feed on Malania and Polygonaceae plants.

Butterflies are attacked by natural enemies from eggs to adults. The egg stage is often parasitized by wasp superfamily insects; Larval stage is the most vulnerable period for predation. Birds, beetles, ground bees, wasps, bedbugs, etc. It is the main predatory natural enemy of butterfly larvae, in which flies, cocoon bees and wasps often parasitize and are often infected by bacteria, fungi and viruses. The natural enemies in pupal stage are wasp, wasp and wasp. The natural enemies of adults are birds, dragonflies, stolen flies, spiders and wasps. For parasitic natural enemies, butterflies are powerless to resist, and the lost population can only be made up by increasing the number of reproduction. For predatory natural enemies, butterflies take active defensive measures and have various preventive mechanisms.
