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 ...
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 ...
Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Their sense of smell is via receptors, usually on the antennae and the mouthparts. Nearly all insects hatch from eggs. Insect growth is constrained by the inelastic exoskeleton, so development involves a series of molts. The immature stages often ...
The game is played with a die (Cootie cube), game board, and Cootie bug parts. The purpose of the game is to build a complete Cootie. To collect parts, players roll the Cootie Cube (die). Each number on the die has a corresponding Cootie bug part. Players must start with the Cootie body first. In order to obtain the body, players must roll a 1.
The underside and head of a female spider. Spiders, unlike insects, have only two main body parts ( tagmata) instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma ). The exception to this rule are the assassin spiders in the family Archaeidae, whose cephalothorax is divided into ...
Thorax (arthropod anatomy) The thorax is the midsection ( tagma) of the hexapod body ( insects and entognathans ). It holds the head, legs, wings and abdomen. It is also called mesosoma or cephalothorax in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that ...
Insect wing. Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax ), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.
