Types of Caterpillars with Identification Chart & Pictures

Caterpillars come in many shapes, sizes, colors, and types. Some types of caterpillars have soft smooth colorful bodies that can be green, black, orange, or white. Some of these caterpillars may have stripped bodies or have interesting camouflage markings. Other kinds of caterpillars have furry bodies, spiky bodies, or horns on their bodies or heads. A caterpillar identification chart can help you identify the different types of caterpillars.

Caterpillars are larval creatures that turn into moths or beautiful butterflies after they metamorphose. Understanding how to identify types of caterpillar allows knowing what they will turn into. For example, one of the most striking types of caterpillar has black, yellow, and white stripes and this turns into the famous monarch butterfly.

Another reason to know how to identify certain types of caterpillars is to know which ones are dangerous or poisonous. For instance, the hair on some furry types of caterpillars can cause irritation when touched.

Types of stinging caterpillars have hollow bristles that contain poisonous toxins. When you touch these dangerous caterpillars, they release the venomous toxins that can cause a wide range of reactions from mild stinging and itching to intense pain. Some spiky caterpillars like the giant silkworm moth caterpillar can even cause death.

So you need to be careful when touching any fuzzy caterpillars even if they look harmless.

Caterpillar Identification

To identify caterpillars, it is important to take note of their size, color, type of hairy covering, and specific markings such as stripes, spots or ‘horns’. Most stinging caterpillars are identified by spine or fine hairs covering their body. Some types of furry caterpillars also look deceiving. For example, some woolly caterpillars look like soft fluffy worms. However, their bristles are a defense mechanism and it can be spiky and painful.

In this article, you will learn about many types of caterpillars and how to identify them properly. You will find out pictures of caterpillars and learn about their unique characteristics.

Types of Caterpillars (With Pictures and Names) – Caterpillar Identification

Even though many types of caterpillars look different and have various characteristics, they all have one thing in common – they love to eat. For example, some types of caterpillars can increase their weight thousands of times in a few weeks.

Let’s look in more detail at these fascinating and interesting-looking worms.
