Attack and Defence

Question 1

Foraging strategies

Answer 1

Sit-and-wait predators - crypsis, amnushers, traps
Active foraging - random, non-random (vibration, sound, chemicals, light)
Phoresy - on host

Question 2

Predator morphology

Answer 2

Raptoral forelegs
Mouth parts (rostrum, elongated mandibles)

Question 3

Crypsis

Answer 3

Insect resembles a general background or invisible object

Question 4

Mimesis

Answer 4

Insects hide in plain sight by resembling natural objects of the environment that are of no interest to the predator

Question 5

Mimicry

Answer 5

Model (gives out warning signal)
Mimic (defending organism)
Observer (predator)

Question 6

Batesian mimicry

Answer 6

When an edible species looks like a distasteful one

Model must be more common than the mimic one

Question 7

Mullerian mimicry

Answer 7

Model and mimic are distasteful and display warning colours

Question 8

Insect colouration

Answer 8

Aposematic colouration
Warning followed by defense mechanism
Requires predators to learn to avoid or have innate avoidance
Sympathetic distasteful species share colours

Question 9

Defense strategies

Answer 9

Catalepsis (frozen posture)
Thanatosis (feigning death)
Aggression (biting/stinging)
Armour (spines/horns)
Masting (synchronous reproduction)
Startle display (eye spots)
Escape behavior (jumping Hemiptera)
Autonomy (shedding of limbs)
