Question
Why did Viceroy butterflies copy the Monarchs?
Solution
Monarch butterflies are not tasty to birds, unlike Viceroy butterflies. Viceroys defend themselves against the birds by emulating the Monarchs, therefore the more they resemble them, the less likely it is that they will become bird supper.

Read the given extract and answer the following questions.

The question he tried to answer was simple: What is the purpose of the twelve tiny gold spots on a monarch pupa? “Everyone assumed the spots were just ornamental,” Ebright said. To find the answer, Ebright and another excellent science student first had to build a device that showed that the spots were producing a hormone necessary for the butterfly’s full development. This project won Ebright first place in the county fair and entry into the International Science and Engineering Fair. There he won third place for zoology. He also got a chance to work during the summer at the entomology laboratory of the Walter Reed Army Institute of Research. |
