Differences of Two Order in Class Insecta:
feed trough a specialised tube formed by some of the mouthpart (prosboscis) for sucking nectar
Have four wings that flap in sync when in flight
scales covering body and wings, modified flattened hair
undergo holometabolous metamorphosis (egg, larvae,pupae, adult)
soft, cylindrical bodies
the forewings are usually larger and are shaped differently from the hind wings.
wings consist of an upper and lower membrane supported by a system of hollow veins
Sense organs on the feet can taste certain food substances
• Valuable in biological research
• As biological indicator
• Economic importance - production of silk from domesticated silkworm (
• Food resource - the larvae of one skipper (
• As pollinator
• Invasive species (
• Parasite on animal - feed on open wounds or bodily secretions of wild or domestic animals
• Feed on woolens, furs, silk and even feathers by fungus moth (Tineid moth)
• Damage the crops including grains, sugarcane, cotton and tobacco
• Damage in beehive by the greater wax moth (
Terrestrial Biomes: tundra ; taiga ; desert or dune ; chaparral ; forest ; rainforest ; scrub forest ; mountains
Wetlands: marsh ; swamp ; bog
Habitat Regions: temperate ; tropical ; polar ; terrestrial
Many species, particularly butterflies, are known to “puddle” at damp places, presumably to obtain dissolved minerals.
Usually stay close to the food plants used by their young and can be found in almost all land habitats. Moth and butterfly caterpillars are usually found on or near their food.

-An emarginated labrum
-A pair of exocrine glands located inside the prothorax
-A thorax fused with the first abdominal sternum
-The dorso-ventral muscles of the abdomen are numerous, short, and arranged in parallel.
-Males of many species possess a unique sclerite termed the vomer which is located above the genitalia and permits the male to clasp the female.
• Most are wingless but some have wing
• Visually large in overall size
• Long thin, antennae
• In stick insect - their legs are spaced out over a very long antennae
• In stick insect - their body is long, thin and cylindrical
• In leaf insect - their body are dorsoventrally flattened with leaf-like projection on body and leg
Live in forests or shrubby areas , tropical climates
Require leaves and woody growth for food and protection
Some phasmids inhabit cooler temperature regions where they overwinter as eggs
1)Skin colouring and marking that is camouflage. 2) Parthenogenesis. 3) Ability of the insect to play dead (thanatosis). 4)egg of the stick insect has appendage known as capitulum full of carbohydrates )Sticky toe pad, used to provide additional grip
1) Slow movement. 2) Many species is wingless or have reduced wing. 3) Reconized causes injurious to forest and shade tree by defoliation
