Lecture 4 - morphology
insects have ___ which means the right and left are ___ images - ANS bilateral symmetry,
mirror
the three distinct regions (head, thorax abdomen) are called? - ANS tagma (all have 3 tagma)
dorsal - ANS back of the insect
ventral - ANS front/underside of the insect
pleural - ANS sides of the insect
color interference - ANS light scattering through reflection of a certain area to show different
colors
pigments - ANS eating foods that are similar colors
seta (setae) - ANS hollow bristles that look like hairs. used for sensory reception, defense,
locomotion/propulsion, camouflage, display
How do insects use colors/markings? - ANS mate recognition, camouflage, warning colors,
startle markings, thermal regulation
What is Batesian mimicry? - ANS a harmless species mimics a harmful one
What is mullerian mimicry? - ANS when two species are dangerous and they look similar to
reinforce the effects of each other
startle markings - ANS used to confuse or startle predators
ocelli - ANS simple eyes that detect differences in light intensity
compound eyes - ANS large, bulbous, made up of many facets
Four main parts of mouth - ANS Labrum(upper lip), mandibles (jaws), maxilla (sensory/feelers),
labium (lower lip)
chewing mouthparts - ANS looks like claws. ants, grasshoppers, beetles.
piercing/sucking mouthparts - ANS feed on liquids. mosquito, cicada, assassin bug
