Caterpillar

The striking caterpillar of the Emperor Gum Moth

A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths).

Caterpillars have long segmented bodies and many sets of "legs". They eat leaves voraciously, grow rapidly, shed their skins generally four or five times, and eventually pupate into an adult form.

Caterpillars have six true legs (being hexapods) on the thorax, up to four pairs of prolegs on the middle segments of the abdomen, and sometimes a single pair of prolegs on the last abdominal segment. The sawfly larva (Hymenoptera) superficially resembles a caterpillar, but can usually be distinguished because the caterpillar has a gap between true legs and prolegs, whereas the sawfly does not. Another difference is that lepidopteran caterpillars have crochets or hooks on the prolegs. The gap between the prolegs and the true legs can vary from a slight gap in some species to a large gap in families such as the geometridae. The geometrids, also known as inchworms or loopers, are so named because of the way they locomote, appearing to measure the earth (the word 'geometrid' means 'earth-measurer' in Greek).

Caterpillars do not breathe through their mouths. Air enters their bodies through a series of small tubules along the sides of their thorax and abdomen. These tubules are called 'spiracles', and inside the body they connect together into a network of airtubes or 'tracheae'.

Caterpillars do not have very good eyesight or senses. Rather than having fully-developed eyes they have a series of six tiny eyelets or 'ocelli' on the lower portion of their head. They rely on their antennae to help them locate food.

Many species of birds and animals consider caterpillars to be a tasty protein snack, so the caterpillars have evolved several methods of protecting and/or camouflaging themselves. These methods can be either passive, aggressive, or both. Some caterpillars have large 'false eyes' towards the rear of their abdomen. This is an attempt to convince predators that their back is actually their front, giving them an opportunity to escape to the 'rear' when attacked. Others have a body coloration that closely resembles their food plant.

More aggressive self-defence measures are taken by the spitfires and hairy caterpillars. These caterpillars have spiny bristles or long fine hairs that will irritate anything that brushes against them, or spit acidic digestive juices at potential enemies. However, some birds, like cuckoos, will swallow the hairiest of caterpillars.

Caterpillar

Some caterpillars eat the leaves of plants that are toxic to other animals. They are unaffected by the poison themselves, but it builds up in their system, making them highly toxic to anything that eats one of them. These toxic species, such as the Cinnabar moth (Tyria jacobaeae) caterpillars, are brightly striped or coloured in red and yellow - the 'danger' colours.

Caterpillars have rightfully been called eating machines. They have the fastest growth rate of any animal in the world. For instance, a tobacco hornworm will increase its own weight ten thousand times in less than twenty days. One of their adaptations that enables them to eat this much is a mechanism in a specialized midgut which transports ions at a very high rate to the lumen (midgut cavity), to keep the potassium level higher in the midgut cavity than in the blood. This mechanism is not found in any vertebrates.

The aim of all these aggressive defense measures is to assure that any predator that eats (or tries to eat) one of them will not be in a hurry to repeat the experience.

Some caterpillars obtain protection by associating themselves with ants. The Lycaenid butterflies are particularly well known. Recent findings have shown that they communicate with their ant protectors by means of vibrations as well as chemical means.

Some caterpillars are considered serious pests of agriculture or forestry. The include the Small White butterfly (brassicas), the Pine Butterfly, and the Codling Moth (apples).

"Tiny, snail-eating caterpillars found in Hawaiian rain forests tie up their prey with sticky silk and snack on them at leisure. [...] It is the first time that caterpillars that eat snails or any other mollusk have been found." July 22, 2005

Other carnivorous species of caterpillars are also known, but still represent a tiny fraction of all known representatives of these insect larvae.

The include the Small White butterfly (brassicas), the Pine Butterfly, and the Codling Moth (apples). According to a report of Center on Philanthropy at Indiana University published by the Giving USA Foundation, as of 2005, there are 1,010,395 charities in the USA. Some caterpillars are considered serious pests of agriculture or forestry. RSPCA Told to Put Human Needs Before Animal Pain). Recent findings have shown that they communicate with their ant protectors by means of vibrations as well as chemical means. This can reduce the possibilities of fraud and increase the opportunities for charities to receive tax breaks; it may also indirectly allow the government to influence the scope and agenda of charities (e.g. The Lycaenid butterflies are particularly well known. In some countries (including the UK, Canada, Australia, and the United States) a charitable organization needs, by law, to register with the government.

Some caterpillars obtain protection by associating themselves with ants. These are set up for specific causes, such as curing diseases; providing goods or services for people or areas that lack them; nature conservation; and many others. The aim of all these aggressive defense measures is to assure that any predator that eats (or tries to eat) one of them will not be in a hurry to repeat the experience. The term is also applied to organizations such as a charitable trust, a charitable foundation, or a corporation set up entirely for charitable purposes. This mechanism is not found in any vertebrates. . One of their adaptations that enables them to eat this much is a mechanism in a specialized midgut which transports ions at a very high rate to the lumen (midgut cavity), to keep the potassium level higher in the midgut cavity than in the blood. Charity is also used as a forename, intended to evoke the idea that one so named is a giving person.

For instance, a tobacco hornworm will increase its own weight ten thousand times in less than twenty days. The act of giving money, goods or time to such a charitable trust or other worthy cause is described as charity or charitable giving. They have the fastest growth rate of any animal in the world. In its most extreme form charity can be self-sacrificial. Caterpillars have rightfully been called eating machines. In Christian theology, for example, it is one of the three theological virtues, meaning loving kindness towards others; it is held to be the ultimate perfection of the human spirit, because it is said to both glorify and reflect the nature of God. These toxic species, such as the Cinnabar moth (Tyria jacobaeae) caterpillars, are brightly striped or coloured in red and yellow - the 'danger' colours. Charity is a central part of most of the world's religions.

They are unaffected by the poison themselves, but it builds up in their system, making them highly toxic to anything that eats one of them. It is one conventional English translation of the Greek term agapē. Some caterpillars eat the leaves of plants that are toxic to other animals. Charity is a term that refers to giving.
