    Study Notes

    Distinguishing Characteristics of Insects

    • Insects are distinguished from non-insect hexapods by having a three-part body (head, thorax, and abdomen) and a hard exoskeleton made of chitin.

    Unique Feature of Insect Body Structure

    • A unique feature of insect body structure is the three-part body (head, thorax, and abdomen) with a hard exoskeleton made of chitin.

    Non-Insect Hexapods

    • Non-insect hexapods belong to the group of arthropods called Entognatha, which includes proturans, collembolans, and diplurans.

    Distinguishing Insects from Other Arthropods

    • Insects are separated from other arthropods by having a three-part body (head, thorax, and abdomen) and a hard exoskeleton made of chitin.

    Ecological Niche Occupation

    • Insects are unable to occupy an ecological niche that requires a large body size, as they have a hard exoskeleton that restricts their growth.
