What are characteristics of Coleoptera?
They have threadlike antennae and long slender legs. These insects are very fast and often difficult to collect. Their agility and strong mandibles make them well-adapted for their predaceous life style.
What are the features of the insect thorax?
The insect thorax consists of three segments (called the prothorax, mesothorax, and metathorax), which may be fused but are usually recognizable. Each segment has four groups of hard plates (sclerites); the groups are the notum (upper), the pleura (sides), and the sternum (underside).
What type of mouthparts do Coleoptera have?
Both larvae and adults have strong mandibulate mouthparts. As a group, they feed on a wide variety of diets, inhabit all terrestrial and fresh-water environments, and exhibit a number of different life styles.
What are the characteristics of insect?
Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms.
What are the characteristics of Lepidoptera?
Lepidoptera are ‘typical’ insects, in that they have 4 wings, 6 legs, 2 antennae and a body divided into 3 sections – a head, thorax and abdomen. The leg and wings are attached to the thorax. In a few species of moths, the females have evolved to become wingless.
What are the three parts of thorax?
The middle tagma, or thorax, comprises three large segments: prothorax (anterior most segment), mesothorax (middle), and metathorax (posterior) (Figure 33.3).

What are the characteristics of Mycalesis?
They are notably polymorphic, with wet- and dry-season forms differing in many species, especially as regards size and number of underwing eyespots. Mycalesis superficially resemble the species Orsotriaena medus, but can readily be identified by the number of spots.
