प्रश्न
Why did Ebright start a project of tagging butterflies?
उत्तर
The last page of the book Travels of Monarch X, which Ebright's mother gave him, contained an invitation. In order to analyse the migration path of monarch butterflies for his research, Dr. Fredrick A. Urquhart requested readers to tag butterflies. Therefore, Ebright put little sticky tags on the monarchs' wings.

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. |
