Butterfly pupae at San Diego Zoo - level 2

The US Fish and Wildlife officials confiscated 130 butterfly pupae. Workers at the San Diego Zoo, which is a zoo in California, took care of them. They carefully unpacked the pupae to see if they were OK.

Then, they hung the pupae up. At a later point, the butterflies will move out of the pupae on their own.

This type of butterfly is known as the Birdwings. It is unusually big and it flies like a bird. It is from India and Southeast Asia.

Difficult words: official (somebody in a position of authority), confiscate (to take something officially), pupa (an insect before it becomes an adult, when a special cover protects it).
