I made an appointment with my classmates to visit the insect specimen exhibition today. There are so many specimens there! There are many I haven't seen. "Stick insects" is one of them. It is distributed in Indonesia and looks like bamboo: its body is like a thin and long bamboo pole, its legs and feet are like dead branches, and its wings are interesting, like transparent bamboo leaves. No wonder it's called "stick bug"! In addition to "stick insects", there are many butterfly specimens: some have many spots, and some are blue to glow. These butterflies have different colors and are worth seeing. When I saw the ancient trilobite fossils and fish fossils, I felt that nature was so great; But when I see black spiders and scorpions, I can't help shivering: I'm afraid they will come back to life and bite me! Finally, I bought a butterfly specimen called "Big Purple Narrow Butterfly". This visit opened my eyes!
