Step 2: Explanation of other options. - (A) Aposematism involves bright warning colors to signal toxicity.
- (B) Batesian mimicry involves harmless organisms mimicking harmful ones to avoid
predation. - (D) M¨ullerian mimicry involves two harmful species mimicking each other to reinforce
predator avoidance.
Step 3: Conclusion.
Moth caterpillars mimicking bird droppings are best described by masquerade, which is a
form of mimicry involving deception through resembling an inedible object.
