Identification of cocoon

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
