Facts You Should Know. Most groups of this insect are herbivores, which means that they feed on crops, while some feed on tiny insects, and the omnivores feed on crops and insects such as an ant.
The diet of a particular caterpillar depends on its habitat when a caterpillar that feeds on crops changes location it might choose to adapt to feeding on ants cause that can be the only source of food in that area.
The funny fact about their diet is that when they turn into a butterfly their diet does not differ as to how it changes in the caterpillar stage, by that time they feed mainly on crops. These insects do not play with their food as they eat quickly, they also need the energy to change their stage, the stage of a caterpillar is of four stages which are egg, larva, pupa, and the adult which all must be completed.
The turning from a caterpillar to butterfly is extremely incredible but caterpillars are pretty amazing insects too! However, as far as this you have known facts about caterpillars you did not know before and you might seem shocked about some that seem impossible for a caterpillar to accomplish at the level of its size.

These question has caused a big confusion, as not all web pages give a full insight about the legs of a caterpillar, some come to conclude that all insect has six legs so if a caterpillar is an insect then it has six legs.
However, the are true to a point but not that true as the caterpillar does not have only six legs, moreover, we conducted interesting and well-groomed research on the legs of a caterpillar feeding you with the right source of information. Caterpillars show to have lots of legs but only six of them are true legs and are the most useful since caterpillars are insects. The prolegs have tiny hooks on the ends which help with walking and climbing on walls to improve their sticky ability.
In addition, the total number of legs that the caterpillar has is eight in number as it has two types of legs, the prolegs and the thoracic. Having read all through this article, not only getting your query answered you have gained lots of interesting facts about the caterpillar and the stages of transformation from caterpillar to butterfly and lots of others.
Most caterpillars have between eight and ten prolegs in total, each pair attached to a different subsection of the abdomen. Instead of looking like regular legs, prolegs tend to have a stubby appearance and are usually the color of the caterpillar. Though the grip is impressive, the prolegs also release quite easily for quick movement.
Even having a caterpillar on you for a few seconds might mean you feel hundreds of leg movements. Rest assured, there are only 16 legs maximum on a caterpillar, though it definitely feels like more every second.
It then rebuilds itself into a butterfly and leaves the unneeded structures behind. In the process, the nubby prolegs are lost. But think about it. Why would a butterfly need prolegs in the first place? The number of prolegs varies between species. Most caterpillars have five. That makes eight pairs or sixteen individual legs in all. The monarch butterfly caterpillar has the classic arrangements of legs, with three pairs of true legs at the front of the body, on the thorax, and five prolegs behind.
The prolegs are grouped as a set of four in the centre of the abdomen and one set of anal claspers at the back. Monarch caterpillars also have two pairs of tentacles, one at the front and one at the back, which can be mistaken for legs from above. Another common leg arrangement is that of the looper or geometrid caterpillars. These have three true legs, with a large gap between these and its two prolegs at the back of its body. Geometrids often use their anatomy to their advantage.
Many have evolved to perfectly mimic a twig by holding onto the plant with their prolegs and stretching out their body to a long stiff form, their head and true legs looking like the bud at the end of the wood. A few caterpillars of the Geometrids have more than two prolegs, some having vestigile prolegs that are much smaller than the rest. Some caterpillars of the noctuid group have a similar body form and are sometimes included in the loopers group or called semi-loopers.
These tend to vary between two to three prolegs. Slug moth caterpillars are something altogether different. These live primarily in tropical areas, and there are over 1, species. Many, such as the monkey slug moth, look genuinely bizarre, and several have nasty stings. Although slug moths have their three true legs still, instead of prolegs they have suckers. They move in a slug-like gliding way, hence their name. Some species even lubricating their path with a type of liquid silk.
Flannel moths like to break our proleg rule in the opposite direction, having seven pairs rather than the usual maximum of five. Looking like a walking tupe, many of these species have a nasty sting. Found in North America and the tropics, they become beautiful fuzzy moths once they reach maturity. A few caterpillars have a particularly interesting adaptation, with their anal claspers changed into a kind of tail.
Some caterpillars are missing a pair of prolegs elsewhere, such as the least black arches. Aside from the unusual slug moth caterpillars slowly sliding their way through the tropics, most caterpillars can be divided into two groups in terms of movements; the crawlers and the loopers.
Most Lepidopterae moths and butterflies caterpillars have three true legs, four prolegs and an anal clasper often referred to as a 5th proleg which they use to walk and to hold on to foliage. However, not all caterpillars have this same distribution of legs. The majority of one large family of moths, the Geometridae , have only one pair of prolegs and a pair of rear claspers which cause them to walk by advancing one end of their body at a time, forming a loop in their folded body.
All insects that undergo a complete metamorphosis have a caterpillar stage. The number of legs can be a useful guide in determining whether a caterpillar is a species of lepidoptera or one of the other many species of insects also with a larval stage, such as a hoverfly, ladybird, beetle or sawfly. Ladybirds above left and beetles only have three true legs and no prolegs. Sawflies above right have more pairs of prolegs which on some species can be seen extending from their three true legs the entire length of their bodies.
The single pale oval holes on the sides of the first and fourth to eleventh segments are breathing holes called spiracles.
