Introduction to the Insectarium: The most eye-catching thing in the Botanical Garden is the Insectarium. The Insectarium is located inside the gate of the Botanical Garden facing the Olympic venues. The entire building is very new and was built in 1990. The Insectarium in the botanical garden is known as the largest insect collection in North America. The exhibition hall is divided into two floors and has multiple theme halls. It displays insect specimens such as bees, praying mantises, beetles, spiders, centipedes, and scorpions, most of which are live insects. In addition, many strange insects are also on display, such as insects with strange survival weapons such as pseudoecology and protective coloration.
