Nov 17, 2022 · How Does An Insect Heart Work? Do all insects have wings; Do Insects Feel Pain? Unlike a human’s vertebral column, an insect’s spine is a cellular outgrowth of its exoskeleton coated in the cuticle. While growing and forming an exoskeleton, a single layer of epidermal cells secretes the cuticle that then hardens and creates a thorn-like spine.

The exoskeleton, sometimes called the cuticle, covers the entire outer body of an insect; there’s no interior skeleton. Made of a polysaccharide derived from glucose, and called chitin, it protects a completely soft interior. The chitin can be firm or yielding, depending on its thickness. So, while an insect’s face and legs have thin layers to allo...
Setae (sing. seta), cover the entire body of most species. They often look like hair, but are actually chitin, like the rest of the insect’s exoskeleton, and can take several forms, including hairy-looking, bristly, and spiny. Setae may also be widened and flattened into scales, like those on the wings of butterflies and moths. Most setae are attac...
Insects produce colors in nearly every hue imaginable, sometimes in spectacular fashion, like some of the scarab beetles and butterflies. The colors are produced in several different ways: Some are the result of ordinary pigments, mainly melanin, which don’t change. But others result from light waves that refract (bend) after striking microscopic r...
Most insects have five senses, but they don’t detect stimuli in the same way humans do. For instance, they don’t have an actual nose, but they do have sensory organs all over their body that serve the same purpose. Insects can: 1. See, using compound eyes for visual resolution, and ocelli for light detection. 2. “Hear” through the movement of recep...
A means of communication among insects is with organic compounds called pheromones (scents). They’re messages that elicit responses from other members of the same species: there’s food over here; come mate with me; stay away from my eggs; help me fight this predator; flee; and more. The pheromones are released through glands located in several plac...
The brain, tiny as it is, can process myriad bits of input, and direct actions to the rest of the body. And, it has a human-like mid-brain structure (although more basic) that demonstrates levels of consciousness! Research suggests that they probably don’t feel grief or jealousy, but they may feel something like hunger and pain, and perhaps a sort ...
Most adult insects have two large compound eyes. They’re comprised of hundreds or even thousands of tiny lenses. Each lens (ommatidium) is connected to an optic nerve and faces a single direction, one that’s just a tad different from all the others. The brain receives and interprets visual input from all of them to form a complete picture. Compound...
In addition to their compound eyes, all adult insects have two or three tiny “simple eyes,” called ocelli (oh-CELL-ee). They have only one lens each, and can’t focus. Located at the top or front of the head (the position varies), their job is to detect the intensity of light and dark. Immature insects—known variously as nymphs, caterpillars, naiads...
Insects don’t have ears, but that doesn’t mean they can’t “hear,” in their own way. Sound waves create vibrations, and insects can detect them through sensory organs attached to stiff hairs scattered here and there on their body. Some species also have these organs on their antennae. A few, including cicadas, grasshoppers, and moths, have a thin ty...
The head has two antennae (an-TEN-ee), with three (some flies) up to 140 (cockroaches) muscled segments. The antennae (singular: antenna) serve as primary sense organs for smell, taste, touch, temperature, humidity, and pressure. They’re flexible and highly varied: long, short or stubby, feathery, bristly, thin, straight, or hair-like. Some even re...
4 days ago · Tibia: often the longest segment of the insect leg- is covered in hairs or spines that aid pollen collection or gripping. Tarsus: the final section of the insect leg is further divided into five sections, tarsomeres, usually ending with tiny claws or pads. Insects do not just use their legs to walk.
Insects don't have spines; they are invertebrates. Insects have segmented bodies. Their bodies are divided three sections - the head, the thorax, and the abdomen. The head has antennae and a pair of compound eyes. Insects have six legs, one pair on each of its three segments. Some insects also have wings. Insects also have an exoskeleton.
In many insects, certain epidermal cells are specialized as exocrine glands. These large, secretory cells produce compounds (e.g. pheromones, repellants, etc.) that are released on the surface of the exoskeleton through microscopic ducts. Tiny hair-like projections or surface sculpturing of the cuticle are known as microtrichae or pile (PILL-EE ...
Large projections are termed spines. These are of multicellular origin. Appendages on the legs of insects, but joint connected, are called spurs. The wings of some insects, like the Lepidoptra, also present large numbers of structures, in addition to normal setae, which are spatulate, or scale-like in shape, and are often highly colored.

Jun 13, 2017 · The blood, or hemolymph, in insects is free-flowing throughout the body cavity and is pumped via the heart.
