This Chinese Mantis was found crawling on the Clay Pit Ponds Nature Center building one early morning.
They were accidentally introduced to Pennsylvania in 1896 by a shipment of plants to a nursery in Philadelphia. Once it was observed that they eat garden pests, people would import mantis egg cases to protect their plants. These insects have spread across much of the eastern and midwestern United States with the classification of non-native in New York.
Fun Fact: Chinese Mantisโ can detect movement up to 60 feet away.
