Butterflies
Physical Features:
1. Three pairs of legs
2. Body divided into 3 parts: head, thorax, and abdomen
3. Large eye on both sides of head; large spherical structures, consists of thousands of omatidea
4. Two pairs of wings
5. Dust-like scales
6. Scales give wings special colors.
7. Good sense of taste
8. release pheromones
9. antennae used for balance in flight
10. no teeth or mandibles
11. feeding mechanism: long double barreled tube: proboscis
Systems:
1. Butterflies pass through four stages in life: egg, larva, pupa, and adult.
2. Reproductive, respiratory, circulatory and digestive systems take place in the abdomen
3. Circulatory system is pretty simple. -> heart is attached to long tube that extends from abdomen to head. Blood is pumped through tube and then released into tissues. Blood seeps through tissue and back to abdomen, sucked back into heart, process occurs again.
4. No transportation of oxygen in blood; use valves called spiracles
5. Males look for females to inseminate; females lay eggs (around 100 in lifetime)
Bees
Physical Features:
1. flying insects related to wasps, ants, hornets, etc
2. short, thick bodies covered with hair
3. six legs
4. three body parts: head, thorax, and abdomen
5. Thorax has three segments with a pair of legs on each
6. tiny waist connects to thorax and abdomen
7. fly about 12.5 miles
8. has two compound eyes made of ommatidia and three simple eyes, ocelli
9. wings
10. antennae
11. mandible, glossa, labrum, and two maxillae
12. stinger
13. leg structure: coxa, throchanter, femur, tibia, metatarsus, and tarsus
14. head contains about 950,000 neurons
System:
1. female mates with several males
2. bee has a colony-level immune response that normally helps heal and infection
3. complex super-organism with physical, chemical, and behavorial defenses at different levels
4. robust immune system that is very effective
5. haploidiploid sex-determination system
6. have two reproductive functions
7. all sperm cells produced by a particular bee are genetically identical
8. main function is to fertilize a receptive queen
9. has a tracheal system
10. open circulatory system (no veins)
