Detailed explanation-1: -Explanation: The butterflies were migrating in response to external stimuli. Migration is the movement of organisms from one place to another in response to external stimuli.
Detailed explanation-2: -The monarch has 2 defence mechanisms The monarch (Danaus plexippus) uses two methods of self-defence – warning colouration and toxicity. The monarch butterfly’s bright colours are warning signs for vertebrates to stay away. Scientists call this aposematic colouration.
Detailed explanation-3: -DESCRIPTION: The monarch is a large orange butterfly that flies with its wings held in a “v” shape. The wings have prominent dark veins and two rows of white spots at the edges, and the body is dark. The wingspread ranges from 89 to 105 millimeters (about 3.5 to 4 inches).
Detailed explanation-4: -The monarch is the only butterfly known to make a two-way migration as birds do. Unlike other butterflies that can overwinter as larvae, pupae, or even as adults in some species, monarchs cannot survive the cold winters of northern climates.
Detailed explanation-5: -The Painted Lady is the most cosmopolitan of all butterflies. It is found all over the world except in some parts of South America and Australia. This wide natural prevalence is remarkable for a tiny butterfly. This is due to its ability to perform long-distance flights.
