    If not that then it does resemble some larvae of other species in Hemitheini. Hoping a book I ordered, Caterpillars of Eastern North America, will help. Posted 6 years ago

    I think it may be Mesothea incertata. https://bugguide.net/node/view/40965
    
    "Larva: green with brown dorsal stripe; body slender and without noticeable bumps or protrusions; head and first thoracic segment with pair of pointed horns."
    
    "Larvae feed mainly on leaves of willow and Sweet Gale (Myrica gale), but also on alder, birch, Buffaloberry (Sherpherdia canadensis), gooseberry, New Jersey Tea (Ceanothus americanus), pine, and members of the rose family (Rosaceae). Associated with Labrador Tea (Ledum groenlandicum) and Bearberry (Arctostaphylos uva-ursi) in Alberta"
