- 1AnatomyEntymology - a branch of morphology
- 2what are the three parts of an insect?Head, Thorax, and Abdomen
- 3What are 6 major features of an insect?External Skeleton (for muscle attachment, body shape, container for the body contents, Protective Covering, Barrier to water loss, soft membranes between hard plates
- 4What are the directional features of an insect?anterior-towards the head
posterior-towards the tail
lateral- towards the side
dorsal-towards the ground
ventral-towards the back - 5what is segmentation?repeating structures and segments of the body, each segment has bits of each system (reproductive(etc) in all parts of it's body *(repetition)
- 6what is the exoskeleton?an organ of the body composed of three principle layers and provides rigidity to the insect form
- 7What are the three layers of the exoskeleton?the basement membrane, the epidermis, and procuticle
- 8what is the function of the basement in the exoskeleton?The basement is a non cellular membrane that covers and makes up the insect mostly
- 9what is the function of the epidermis on an insect?a cellular layer that secrets the cuticle
- 10what is the function of the procuticle in the exoskeleton?the pro cuticle is made up of a protein and carb mixture and is hard but flexible
- 11what are the three parts that make up the procuticle?the endocuticle, the exocuticle, and the epicuticle
- 12what is the function of the epicuticle in the procuticle?this part keeps the insect from drying out is mad of a waxy protein that maintains moisture and protects from parasites and is the outermost layer
- 13what is the function of the exocuticlechitin microfibers, hardened plates called sclerites
- 14what are the three main parts of an insect head?vertex, compound eye, ocellus, antennae-sensory, mouthparts-shperical design for chewing or pumping, mandible, palp-similar to antannae
- 15What are the major types of mouth parts?chewing-beetles, grasshopper
piercing-sucking aphids-mosquitoes, many of these cause diseases
siphoning-butterflies, moths- rolled up mouths, nectar feeders
chewing lapping-honeybees both chew and have tongues
sponging-flies dissolve and sponge up food - 16What are the three main parts of the thorax?prothorax, mesothorax, metathorax
- 17what are the traits of the prothorax?attached to the first pair of legs (never has wings)(covered by pronotum)
- 18what are the traits of the mesothorax?2nd pair of legs and 1st pair of wings
- 19what are the traits of the metathorax?3rd pair of legs 2nd pair of wings
- 20QQ: What sort of creatures have wings?birds, bats, and insects
- 21what is a characteristic of the prothorax?treehoppers a defensive appendage that can come off a creature in the event it is attacked
- 22What are the key characteristics of insects legs?multi segmented, for flexibility:
coxa- attaches to hip
tibia-lower leg
femur-big upper leg
tarsus-foot area - 23what are Fossorial?digging legs
- 24what are saltatorial legs?legs for jumping
- 25What are some of the key traits of wings in insect?rare among fauna, on the 2nd and 3rd thoracic segments
- 26What are a few of the chronological traits of insect wings?some insects lost their wings (fleas)
some changed over time (hemiptera), some never had wings - 27What are a few of the basic designs of wings in insects?Large membrane full of veins, hemiptera (true bug half wing (fly)
Elytra - hardened fully does not flap typical in beetles
Diptera forewings membranes large
lepidoptra-scales butterflies - 28What are key traits of insect abdomen?spiracles-breathing holes
cerci-silverfish, modified for defense
ovipositor-egg layer only in females - 29QQ: What is the sting?Modified ovipositor that is only in females
