| Anatomy | Entymology - a branch of morphology |
| what are the three parts of an insect? | Head, Thorax, and Abdomen |
| What 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 |
| What 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 |
| what 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) |
| what is the exoskeleton? | an organ of the body composed of three principle layers and provides rigidity to the insect form |
| What are the three layers of the exoskeleton? | the basement membrane, the epidermis, and procuticle |
| what is the function of the basement in the exoskeleton? | The basement is a non cellular membrane that covers and makes up the insect mostly |
| what is the function of the epidermis on an insect? | a cellular layer that secrets the cuticle |
| what 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 |
| what are the three parts that make up the procuticle? | the endocuticle, the exocuticle, and the epicuticle |
| what 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 |
| what is the function of the exocuticle | chitin microfibers, hardened plates called sclerites |
| what 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 |
| What 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 |
| What are the three main parts of the thorax? | prothorax, mesothorax, metathorax |
| what are the traits of the prothorax? | attached to the first pair of legs (never has wings)(covered by pronotum) |
| what are the traits of the mesothorax? | 2nd pair of legs and 1st pair of wings |
| what are the traits of the metathorax? | 3rd pair of legs 2nd pair of wings |
| QQ: What sort of creatures have wings? | birds, bats, and insects |
| what is a characteristic of the prothorax? | treehoppers a defensive appendage that can come off a creature in the event it is attacked |
| What 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 |
| what are Fossorial? | digging legs |
| what are saltatorial legs? | legs for jumping |
| What are some of the key traits of wings in insect? | rare among fauna, on the 2nd and 3rd thoracic segments |
| What 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 |
| What 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 |
| What are key traits of insect abdomen? | spiracles-breathing holes cerci-silverfish, modified for defense ovipositor-egg layer only in females |
| QQ: What is the sting? | Modified ovipositor that is only in females |
