Insects live in a world of motion. This leaf-footed bug climbs wind blown grass and flies off. Insects (from Latin insectum) are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen ), three pairs of jointed legs ...
Insect physiology includes the physiology and biochemistry of insect organ systems. [1] Although diverse, insects are quite similar in overall design, internally and externally. The insect is made up of three main body regions (tagmata), the head, thorax and abdomen. The head comprises six fused segments with compound eyes, ocelli, antennae and ...
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata) (head, thorax ...
Entomology. Diversity of insects from different orders. Entomology (from Ancient Greek ἔντομον (entomon) 'insect', and - λογία ( -logia) 'study') [1] is the scientific study of insects, a branch of zoology. In the past the term insect was less specific, and historically the definition of entomology would also include the study of ...
Insect biodiversity. Insect biodiversity accounts for a large proportion of all biodiversity on the planet—over half of the estimated 1.5 million organism species described are classified as insects. [1] [2] A pie chart of described eukaryote species, showing just over half of these to be insects.
Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] Insects play significant roles in the ecology of the world due to their vast diversity of form, function and lifestyle; their considerable biomass; and their interaction with plant life, other organisms and the ...
Insectarium. An insectarium is a live insect zoo, or a museum or exhibit of live insects. Insectariums often display a variety of insects and similar arthropods, such as spiders, beetles, cockroaches, ants, bees, millipedes, centipedes, crickets, grasshoppers, stick insects, scorpions, mantises and woodlice. Displays can focus on learning about ...
Imago. In biology, the imago ( Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage ("imaginal" being "imago" in adjective form), the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.
