Did you know that caterpillars have a unique feature called "stemmata" or "ocelli" that function as simple eyes?
These light-sensitive cells differ from the compound eyes found in adult insects on the sides of the Caterpillar's head in pairs. The number of ocelli can vary from species to species, with most having six arranged in three pairs.
However, some caterpillars may have fewer or additional ocelli. Despite their small size, these ocelli play an essential role in helping caterpillars detect changes in light intensity and navigate their environment, especially during low-light conditions.

Are caterpillars insects? The answer is yes, but they are an incomplete form of certain insects4. Caterpillars are the larval stage of 180,000 insects belonging to the order Lepidoptera, which includes butterflies and moths. Caterpillars develop to become their winged adult form.
Generally, caterpillars have a cylindrical body shape with a segmented structure. Each body segment typically bears a pair of legs.
They live on every continent except Antarctica. Some countries known for their diverse caterpillar populations include the United States, Brazil, Australia, India, China, and African and European countries.
One interesting fact about caterpillars is that they have two types of legs: true legs and prolegs or false legs.
The true legs are the three pairs of jointed legs located on the Caterpillar's thoracic segments closest to its head. These legs are"true" because the Caterpillar retains them into adulthood when it transforms into a butterfly or moth. They use these legs to crawl and walk.
Additionally, on their abdomen, caterpillars possess several pairs of fleshy, unjointed prolegs adorned with tiny hooks called crochets. A caterpillar may have up to five pairs of prolegs, but the number can vary among species. These prolegs firmly grip surfaces as they move about while feeding or resting.
However, caterpillars shed these prolegs as they approach pupation, developing structures needed for metamorphosis into chrysalides or pupae during their transition to adult butterflies or moths.
Additionally, sometimes larvae from the Hymenoptera order - which includes ants, bees, and wasps - get mistaken for caterpillars. However, there are key differences. For example, sawfly larvae superficially resemble caterpillars but have unique features. They sport prolegs on each abdominal segment, unlike caterpillars. Caterpillars have hooks on their prolegs, a feature not found in sawfly larvae.
Different caterpillar species have evolved to feed on specific host plants1, a fact often reflected in their common names. For example, the Monarch Butterfly Caterpillar feeds exclusively on a milkweed plant5, while the Swallowtail Caterpillar consumes plants from the Apiaceae (carrot) family.
However, few caterpillar species have evolved to be carnivorous or omnivorous. These caterpillars have adaptations that allow them to eat insects or other small animals. Examples of carnivorous caterpillars include the Harvester Caterpillar, which feeds on aphids, a favorite of the ladybug, and the Lacewing Caterpillar, which preys on small insects.
Next on our caterpillar facts is their stinging abilities. Stinging caterpillars, like the Puss Caterpillar, Io Moth Caterpillar, and Flannel Moth Caterpillar, possess specialized structures with venomous spines or irritating substances as a defensive adaptation. Found in various regions of North and South America, these caterpillars deliver painful stings when touched, deterring predators and potential threats.
Contact with the venomous spines can cause localized reactions, such as an intense burning sensation, swelling, and redness.
While the stings can be uncomfortable and lead to allergic reactions in some cases, they are generally not life-threatening for humans and subside over time without medical intervention.
However, it is best to avoid handling or touching caterpillars in the wild, especially if unsure of their identification, and exercise caution when exploring natural habitats where other caterpillars may reside.

Another caterpillar fact that you might be interested in is that silkworm caterpillars can spin silk threads from a particular protein in their salivary glands.
They use this silk to weave a cozy cocoon for protection as they transform into pupae. The silken thread spun by a single silkworm can be up to 900 meters long, over half a mile! Humans have been breeding silkworms for their silk for thousands of years, a practice known as sericulture.
While silk and silk fabric have many uses, including in fashion and medicine, silk production involves boiling the cocoon killing the moth.
Scientists are exploring ways to use silk in medical applications like stitches, artificial skin, and drug delivery systems because our bodies accept silk more quickly than other materials.

Corn snakes, like many colubrid snakes, are not venomous because they lack the specialized glands and fangs required for venom production and delivery. Instead, they are constrictors, which means they subdue their prey through constriction rather than venom injection. Corn snakes have powerful muscles and flexible bodies that can overpower their game.
A corn snake detects potential prey by using its keen sense of smell and flicking its tongue to pick up scent particles in the air. When the time is right, the corn snake strikes, seizing the prey with its sharp teeth and coiling its body around it. They then swallow their prey whole, usually head first.
Pythons have several names. Each name reflects something unique about the python, whether it's a physical trait or the region they call home. Consider the Ball pythons, also called Royal pythons. It's an odd name for a snake, but it perfectly captures its tendency to curl into a tight ball when feeling threatened.
This little snake hails from sub-Saharan Africa, and although it's the smallest species on the continent, its name is undoubtedly a big conversation starter.
Now, let's journey to Southeast Asia, where we encounter two remarkable species: Burmese pythons, known for their immense size, takes its name from its homeland, Burma (now Myanmar), and the reticulated python, which got its name from its appearance. 'Reticulated' describes something resembling a net or network, perfectly describing the intricate pattern adorning this python's skin.
As apex predators, pythons maintain the delicate balance of ecosystems. Their primary contribution lies in controlling the populations of rodents and other small creatures, which is no small task considering their rapid breeding rates.
Their insatiable appetite is a natural barrier against an unchecked explosion of rodent populations, preventing ecological imbalance. Rodents are notorious disease carriers, transmitting Lyme disease, leptospirosis, and even the plague.
By regulating rodent populations, pythons unintentionally help curb the spread of these diseases, promoting healthier and balanced ecosystems.
Beetles, belonging to the order Coleoptera, are incredibly diverse insects that comprise a quarter of all known living organisms! There are an estimated 400,000 identified species of beetles, with so many species yet to be discovered1. Among them, there are size variations that would make your jaw drop.
On one end of the scale, we have the almost invisible feather-winged beetles, no larger than 0.01 inches. The Fringed Ant Beetle (Nymphister Kronaueri) is the smallest known beetle and measures around 0.25 millimeters in length. On the other end, the Goliath Beetle, which can grow to 6.7 inches and weigh 1.8 ounces, is one of the longest and heaviest insects in the world.
Furthermore, beetles live in almost every habitat except the extreme polar regions. They live in the driest deserts and the wettest tropical rainforests!
Gorillas are the largest primates on Earth. Adult female gorillas tip the scales at 70-90 kg, whereas their male counterparts, standing tall at a whopping six feet, can weigh anywhere from 300 to 450 pounds. That's roughly equivalent to 135 to 200 kilograms!
The largest being the eastern gorillas, specifically the silverback males from the eastern lowland gorillas. These creatures can clock in at 400 pounds, equivalent to 180 kilograms, and stand tall at approximately 5.6 feet or 1.7 meters. These impressive creatures live in the forests of Central Africa.

Moose are the largest and heaviest extant species in the deer family. From the towering Alaskan moose of the North American wilderness to the more modestly-sized European moose, the eight moose sub-species illustrate these intriguing creatures' adaptability and ecological variety. They belong to the Cervidae family, including other members such as elk, caribou, and white-tailed deer.
With adult males weighing between 900 and 1,400 pounds, moose tower above their deer relatives. On the other hand, female moose weigh an average of 800 to 1,300 pounds. These majestic animals can also stand up to 6.5 feet tall at the shoulder.
Moose are not only known for their size but also their distinctive physical characteristics. They have elongated faces and an overhanging muzzle that extends beyond their upper lip. Furthermore, moose have relatively large and mobile ears that can rotate independently.
Adult male and female moose have a flap of skin, known as a bell or dewlap, hanging beneath their chin. The size of the bell increases with age and is more pronounced in dominant males. It serves as an additional visual display during the fall mating season and helps intimidate rival males.
The scientific name of the moose is Alces alces. However, other countries don't call them "moose." In British English, these majestic animals are more commonly called "elk." The largest moose population is in Canada, whose residents call them rubber-nosed swamp donkeys.
The term "elk" comes from the Old Norse word "elgr," which various European languages later adopted to refer to this animal. When European settlers arrived in North America, they met the indigenous Algonquin people who called the animal "moose" or "smoosh," which means twig-eater or stripper and eater of bark.
This naming inconsistency has caused some confusion. In North American English, "elk" refers to a completely different species of deer, scientifically known as Cervus Canadensis. North American elk, also called wapiti, share a few similarities with moose, such as antlers and herbivorous diet. However, they are smaller in size and have a distinct appearance.
