Your photo is of an Imperial moth. The more yellow color tells me it is a male, the females have more brown markings. This is one of the giant silk moths in the family Saturniidae. Being so large they do fly rather awkwardly.
The adults come to lights at night. They do not feed.
Larva come in a green or brown coloration. According to Bugguide, larvae feed on leaves of Bald Cypress, basswood, birch, cedar, elm, hickory, Honeylocust, maple, oak, pine, Sassafras, Sweetgum, sycamore, and walnut.
The larva pupate in burrows in the soil. The pupa stage is what overwinters, so the adult comes out in summer.
In Newark you probably only have one generation per year.
They are beautiful moths.
