Among earthworms, also called annelids, there are three ecological groups. You can observe worms from these groups to aid worm identification.

Earthworms that prefer to live and eat at the surface are epigeic earthworms. They tend to range from 1 to 7 centimeters long and are reddish-brown. They have darker skin on their backs, probably to protect them from sunlight. Millions of earthworms can live in an acre of land. Those earthworms that favor living in mineral soil are endogeic earthworms.

They lack skin pigmentation, so they are paler, and some of them are bluish, yellow, pink or white. These earthworms like to eat mineral soil for its micro-organisms.

You may find them under rocks and logs, or they may emerge after rainfall. These worms tend to range from 2 to 12 centimeters long. A third type of earthworm is the kind that likes to burrow deep underground; these are anecic earthworms.

They can grow to a fairly large size, as long as 15 centimeters, and are red-brown in color. These worms can eat a great deal off of a forest floor. While they are quite different from each other, there are at least three similarities between earthworms and tapeworms.

They both have muscular systems. They both have a mesoderm. And another of the three similarities between earthworms and tapeworms is that they possess a central nervous system. While a number of caterpillar and worm types work as pests or parasites, many do provide benefit to the environment. Caterpillars become butterflies and moths that can pollinate plants, which then can produce fruits and seeds for people and animals to consume.

Caterpillars are also essential for pollinating native species. It is crucial to provide native plants for caterpillars because they are choosy animals, and invasive or introduced plants are often not favored. Some worms greatly benefit the environment, not just as food for other animals, but for their earth-turning and composting abilities. She spent nine years working in laboratory and clinical research.

Facts on Caterpillars. Caterpillars have long hairs or bristles on their bodies, which can detach and lodge into the skin or mucous membranes of the predator.

This poison is so powerful that in the case of the South American silk moth, it can be fatal to human beings. Much like worms, caterpillars also spit juices and produce bad smells to ward off attackers. Caterpillars also have the ability to create a silk line and drop out of site if a predator approaches.

One of the most obvious differences between caterpillars and worms is caterpillars move around on three pairs of legs, while worms have no limbs at all. Worms move around by contracting their segments. Each segment has two pairs of hairs called setae. The setae help worms grip the soil or other materials.

In general, worms and caterpillars move slowly. When faced by an attacker, however, they can move fairly quickly. No, only caterpillars, which have 3 pairs of legs, become a butterfly or a moth. They are different sizes, colors, and shapes.

The cocoons are all different also! You can tell what kind of butterfly a caterpillar is going to change into! Very interesting, but I would like to know…do caterpillars become butterflies, and do worms become moths?

Do caterpillars mainly live above ground? Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.
