School Tours

Learning about the world of entomology is essential for every science lesson plan. Our museum is filled with species from all over the planet that engage students and showcase insect’s incredible adaptations, diverse habitats, and unbelievable camouflage.

Our lessons and activities are all specifically designed to complement and address the Next Generation Standards that students are tested on. Coming to the Philadelphia Insectarium and Butterfly Pavilion isn’t just a fun experience, it effectively takes the place of certain lessons that would have to be taught regardless in the classroom.

Featured Arthropod

The Macleay’s Spectre, a large stick insect from Australia, is a fascinating example of adaption. Its camouflage makes it nearly indistinguishable from its leafy home.

In addition to their incredible camouflage, their bodies contort like a scorpion’s attack pose when threatened to ward off predators, and their bodies are able to sway in the breeze, just like a leaf.

Come visit and see how many you can spot!
