Identification of cocoon

Asked April 29, 2020, 7:29 AM EDT

This cocoon is located in a red maple tree in the Lochern area. Can you identify the species? Is this indicative of an invasive or harmful species? Thank you.

This looks like a bagworm cocoon. This is a serious pest and a defoliator of evergreens and some deciduous trees. Handpick and throw in the trash. Here is our website for photos and management https://extension.umd.edu/hgic/topics/bagworms-trees-and-shrubs
