Perth Amboy residents report sightings of beautiful monarch butterflies who are on their way from Canada to Mexica during their annual fall migration. Every fall in late September, October and through November the stunning orange and black monarch butterflies make stops in NJ during their migration travels. In front and backyards and in gardens and along the waterfront, Perth Amboy residents are enjoying the many monarch butterflies that have appeared. The butterflies enjoy flower nectar and feed off the native plants in NJ. The NJ DEP has a Monarch Butterfly Conservation Guide.The New Jersey Department of Environmental Protection (DEP) has a mission to protect the wildlife and natural resources in the state for continued benefit of the public. The purpose of the Monarch Butterfly Conservation Guide is to educate people about the monarch butterfly and to provide recommendations to enhance its habitat and numbers. Protecting monarch butterflies is important as they were listed as endangered threatened with extinction because of their habitat destruction and climate change.
