-1 pair of chelicerae (fang-like)
-ex: spiders
crustacea correct answers -2 pairs of antennae
-biramous appendages (pinchers)
myriapoda correct answers -1 pair of atennae
-respiration via tracheal system
-ex: centipede
athropod classification correct answers -major sister phyla:
P. mollusca
P. annelida
-dubious arthropods
P. targigrada
P. onychophora
-definite arthropods
P. athropoda
tardigrada correct answers waterbears
-can withstand extreme temps
subphylum atelocerata correct answers -one pair of atennae
-unbranched (uniramous) appendages
-tracheal system
class hexapoda correct answers subclass entognatha
-mouthparts enclosed
subclass ectognatha
-mouthparts projected forward

insect diversity correct answers 52% of species are insects and estimated 5-30 mil
species
most common insects correct answers coleptera (beetles), lepidoptera
(butterflies/moths), hymenoptera (ants/bees/wasps), diptera (flies)
insect abundance correct answers very high abundance
-170 million bugs/person
consequences of diversity and abundance correct answers 1. insects exploit almost
every resource
-tobacco leaves, oil pools, nuts, hot springs, skin pores
-also in every climate or habitat (even extreme temps/altitudes) except marine
environments (still has arthropods tho)
2. inevitable interactions with humans
-direct attack/harm
-indirect attack: resource competition
-beneficial food and produce food products
types of human interactions: afflictions correct answers -destroy food
-destroy materials (ex: cotton)
-destory body tissues
-transmit disease
-annoying/painful
types of human afflictions: benefits correct answers -useful products (honey/silk)
-food source
-pollination
-pest control (biological control)
- waste decomposition (dung)
-forensic science info
-ecosystem participants
-basic research
-art and decoration
-medicine
