The life of butterflies is closely connected to flowering plants, which their larvae ( caterpillars) feed on, and their adults feed and lay their eggs on. They have a long-lasting history of co-evolution with flowering plants. Many of the details of plant anatomy are related to their pollinators, and vice versa. [2] The other notable features of butterflies are natural gas in spanish their extraordinary range of colours and patterns, and their wings. These are discussed below.

Angiosperms (flowering plants) evolved in the Lower Cretaceous, but did not become common until the Upper Cretaceous. Butterflies were the last major 10 gases group of insects to appear on the planet. [1] They evolved from moths in the latest Cretaceous or the earliest Cainozoic. The earliest known butterfly fossils date to the mid Eocene epoch, between 40–50 million years ago. [3]

Like moths, butterflies have four wings covered with tiny scales. When a butterfly is not flying, its wings are usually folded over its back. The wings are patterned and are often brightly coloured. There are many different kinds of butterflies. The males and females of each kind are often slightly different from each other. Butterfly watching is a popular hobby. Some people also keep collections of dead butterflies that they have caught.

Like most insects, butterflies have three main body parts. These parts are the head, the thorax, and the electricity hair stand up abdomen. The body is protected by the exoskeleton. The body is made up of sections, known as segments. In between the segments there are flexible areas that allow the butterfly to move. All three parts of the body are covered in very small scales. The scales give the butterfly its color. [4] Wings and flight [ change | change source electricity questions grade 6 ]

Butterflies have a very characteristic flying style. They usually do not fly in straight lines. Their style is well described by the children’s version of their name: ‘flutter-by’. Some species are capable of strong, long flights (see monarch butterfly migration) and others never leave the woods they were born in. They can survive bird pecks on the wings quite well. Late in the season damage to their wings can often be seen, and electricity physics ppt still they continue flying quite well.

The mouth of an adult butterfly does not have jaws. It has a kind of mouth that is made to suck liquids. This mouth is called a proboscis. The proboscis is made up of two hollow tubes. The tubes are locked together in the middle. When the butterfly is not using its proboscis, it is coiled up in the head. It can uncoil the proboscis when it wants to feed. [4]

The legs of a butterfly are made for walking, holding onto things, and tasting. There are three pairs of legs. [4] There are four main parts of the leg. They are the trochanter, the femur, the tibia, and the foot. [5] At the end of each foot, there is a pair of claws. Butterflies in the family Nymphalidae have very short front legs. They keep there front legs close to their bodies. This makes it look like they only have two pairs electricity usage calculator spreadsheet of legs. [4] In some species, there is a movable body part on the tibia that is used to clean the antennae. [6]

The abdomen is the third part of the body. It is made up of ten segments. The abdomen gas mask bong review is much softer than the head and the thorax. At the end of the abdomen are the reproductive organs. In the male, there is a pair of claspers. They are used to hold on to the female during mating. In the female, there is a tube made to lay eggs.

Butterflies go through complete metamorphosis. This means that there are four parts in a butterfly’s life. The first part is the egg. The second part is the caterpillar electricity icon (sometimes called the larva). The third part is the chrysalis (sometimes called the pupa). The fourth part is the adult (sometimes called the imago). [4] Egg [ change | change source ]

Butterfly caterpillars can vary in size, color, and shape. They may have spines, bristles, or soft body extensions. All caterpillars have 13 body segments. The first three segments make up the thorax. The thorax has three pairs of legs. These legs are called true legs. The other 10 segments make up the abdomen. The abdomen has five pairs grade 6 science electricity multiple choice test of soft legs called prolegs. The prolegs have tiny hooks at the end of the each foot. They are used to hold on to things. The hooks are called crochets. [4]

A caterpillar’s skin does not grow. As the caterpillar grows inside its skin, the skin becomes too tight. In order for the caterpillar to grow bigger, it sheds its too-tight skin. After the old skin is shed, there is a new, larger skin. This is known as molting. A caterpillar will molt four to five times before turning into a pupa. Each part between molts electricity bill nye worksheet is called an instar. [4]

Some species of caterpillars (in the family Lycaenidae) are tended by ants. The caterpillars have special glands that make a sweet liquid called honeydew. The ants like the honeydew. In return for the honeydew, the ants protect the caterpillars from predators. The caterpillars also have special body parts that make sounds. The caterpillar will make sounds with the body parts and call the ants when the caterpillar is being attacked by predators. The ants hear the sounds and come to protect the caterpillar. [7]

Caterpillars in the family gas house gang Papilionidae have a special organ. This organ is called an osmeterium. It is a bad-smelling gland that is shaped like a snake’s tongue. It is kept behind the inside of the head. When a predator tries to eat the caterpillar, the caterpillar will release the osmeterium. This scares the predators away.

Many pupae are easy for predators to attack. Some caterpillars (in the family Hesperiidae and the subfamilies Parnassiinae and gas 4 less Satyrinae) make shelters out of silk and leaves to protect themselves when they become pupae. These shelters are called cocoons. Most butterfly pupae do not have cocoons to protect themselves. Instead, the pupae have brown or green colors to camouflage themselves among leaves and branches. Pupae that do not have cocoons are called chrysalids or chrysalises. [4] Survival [ change | change source ]

Some butterflies may be in trouble because of habitat loss. Because of the destruction of forests and grasslands, some types of butterflies have nowhere to feed and lay eggs. To help, some people plant a butterfly garden with flowers having lots of nectar for butterflies to feed on. Some people also keep plants that butterflies lay eggs on, and enjoy watching the caterpillars hatch out and feed on the plant. Chemical sprays that are used to keep pests la gasolina cancion away from garden plants, also kill butterflies.
