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.

Clemson was named as "Public School of the Year" in 2001 by Time Magazine for its "Communication across the Curriculum" program. Recent findings have shown that they communicate with their ant protectors by means of vibrations as well as chemical means. Continued distinctions continue into the 2000s. The Lycaenid butterflies are particularly well known. News & World Report magazine.

Some caterpillars obtain protection by associating themselves with ants. In 1995, the Carolina Panthers played their inaugural season in Clemson, and in 1997, Clemson was ranked as one of the "Top 50 Public Universities" in the United States by U.S. 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. In the 1990s, Clemson underwent additional transformations, which included an internal restructuring of the university from nine colleges into five, in an effort to streamline operations and cut costs. This mechanism is not found in any vertebrates. Sportscaster Brent Musburger once described the Tiger's entrance, or "running the hill," as "the most exciting 25 seconds in college football.". 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. Memorial Stadium (or "Death Valley") nearly doubled its capacity during these years of popularity, with many games selling out to this day.

For instance, a tobacco hornworm will increase its own weight ten thousand times in less than twenty days. They also defeated conference rival Wake Forest 82-24, setting numerous stadium, school, and conference records. They have the fastest growth rate of any animal in the world. During the 1981 season, the Tigers beat top 10 teams Georgia, North Carolina, and Nebraska. Caterpillars have rightfully been called eating machines. Clemson achieved great recognition during its 1981 football season, when the Tigers were undefeated, winning the Orange Bowl 22-15 over the Nebraska Cornhuskers to become national champions. These toxic species, such as the Cinnabar moth (Tyria jacobaeae) caterpillars, are brightly striped or coloured in red and yellow - the 'danger' colours. The University continued to expand into the 1970s when enrollment topped 10,000 for the first time.

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. Clemson's expanding student body and expanded academic offerings prompted college administrators to submit to the South Carolina legislature to change its name to Clemson University in 1964. Some caterpillars eat the leaves of plants that are toxic to other animals. Lucinda Harris, who entered a semester later, would become the first African-American female student, and later married Gantt. However, some birds, like cuckoos, will swallow the hairiest of caterpillars. In sharp contrast to the strenuous and violent situations at other southern universities in the early 1960s, Clemson became peacefully integrated on January 22, 1963, when Harvey Gantt became the first African-American student at Clemson. 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. Cooper Library, the Bryan Mall and "Shoebox" residence areas, and the innovative Lee Hall were also constructed.

More aggressive self-defence measures are taken by the spitfires and hairy caterpillars. Throughout the 1960s and 1970s, additional buildings, including the R.M. Others have a body coloration that closely resembles their food plant. Today, only one of the original Johnstone buildings is still standing on the campus. 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. Much of the building was torn down by 2004. Some caterpillars have large 'false eyes' towards the rear of their abdomen. The building's appearance became noticeably bad leaving many to feel that it was more of an eyesore on the campus.

These methods can be either passive, aggressive, or both. Over time, Johnstone became a "landmark" for students and alumni, although perhaps not always in a good way. 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 slabs weighed 224 tons and were nine inches thick, 122 feet long, and 43 feet wide. They rely on their antennae to help them locate food. This method - the Youtz-Slick "lift-slab" method - lifted reinforced concrete slabs onto columns with hydraulic jacks. Rather than having fully-developed eyes they have a series of six tiny eyelets or 'ocelli' on the lower portion of their head. The Johnstone Hall complex became a model for college dormitories, implementing a new raise-slab construction method, a practice which was featured in many architectural magazines at that time.

Caterpillars do not have very good eyesight or senses. The campus also experienced a frenzy of construction during the 1950s, as new academic buildings and contemporary student housing was constructed. These tubules are called 'spiracles', and inside the body they connect together into a network of airtubes or 'tracheae'. training remained until 1969. Air enters their bodies through a series of small tubules along the sides of their thorax and abdomen. Compulsory R.O.T.C. Caterpillars do not breathe through their mouths. Following this advice, the first women were enrolled in Clemson in 1954, also the first year the school entered civilian status.

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). In its findings, the group recommended that Clemson drop its military status and become a civilian institution and that it should enroll women. 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. In 1953, a consulting firm was enlisted to help Clemson college plan a path for its future. Another difference is that lepidopteran caterpillars have crochets or hooks on the prolegs. Edwards. 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. Cooper and Robert C.

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. Bill providing increased opportunities for Americans to go into higher education, Clemson experienced a significant period of expansion under the leadership of two long-serving presidents, Robert M. They eat leaves voraciously, grow rapidly, shed their skins generally four or five times, and eventually pupate into an adult form. As a result of the G.I. Caterpillars have long segmented bodies and many sets of "legs". Only the United States Military Academy and Texas Agricultural and Mechanical University (since 1963 Texas A&M University) provided more. A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths). Clemson ranked third in the country in institutions providing Army officers.

          . Henry Aubrey Strode was selected by the Clemson Trustees to lead the new institution. A president would also be appointed by the trustees to oversee the day-to-day operations of the college. Clemson called for a 13-member Board of Trustees to govern the course of Clemson Agricultural College, with seven "lifetime" trustees and six trustees selected by the South Carolina state assembly to serve two-year terms.

          They participate in the NCAA's Division I (I-A for football)and in the Atlantic Coast Conference (Atlantic Division). The school's sports teams are called the Tigers. Plans for the campus also include a full-scale, four-vehicle capacity rolling-road model wind tunnel. Private sector companies that have committed so far to establishing offices and/or facilities on the campus include the Society of Automotive Engineers and The Timken Company.

          BMW, Microsoft, IBM, and Michelin are all corporate partners of CU-ICAR. The campus also includes an Information Technology Research Center being developed by BMW Manufacturing Company. CU-ICAR will include a graduate school to open in 2006 with Master's and Doctorate level degrees in automotive engineering, offering programs focused on systems integration. The university's newest academic endeavor is the Clemson University International Center for Automotive Research (CU-ICAR)[1] a 250 acre automotive and motorsports research campus located in nearby Greenville.

          The University's most noted academic programs include those in agriculture, architecture, business, education, engineering, nursing, and textile studies. Academically, the university is divided into five colleges: Agriculture, Forestry and Life Sciences; Architecture, Arts and Humanities; Business and Behavioral Science; Engineering and Science; and Health, Education and Human Development. Today, Clemson is classified by the Carnegie Foundation as a Doctoral/Research University-Extensive, a category comprising less than 4 percent of all universities in America. Clemson's engineering program ranks 57th in the country.
