Insect defenses Flashcards
Primary insect defenses
cryptic color
mullerian
batesian
aggressive
cryptic coloration
change color, resemble inedible object to hide
poop, plant, casing
must
-behave
-important when rest
-mostly nocturnal
-dont usually aggregate
interferes with feeding and mating
Mullerian mimicry
-warning colors (typically red, orange, yellow alternating with black)
-nasty (secondary defense)
monarchs and viceroys
Batesian mimicry
edible and has disguise to look poisonous
must
-have model be poisonous and more common than mimic
-slight resemblance has value
Aggressive mimicry
look, behave, and smell like hosts
Secondary insect defenses
flight patterns
death feigning
spines/stings
detachable body parts
deflection of attack
startle displays
chemical defenses
integrated defenses
flight patterns
evasive (tumbling), abrupt color change (closing wings butterflies), startle response (flash), signaling (clicking)
spines
hymenopteran sting to paralyze, social ones sting venom for vertebrates, female sting (ovipositor)
deflection of attack
other body parts resemble important ones that are able to be lost if needed
startle display
make predator hesitate (sudden movement, threat posture)
integrated defenses
different life stages to resemble different disguises
