Hop {Hamulus lupulus), and English Elm ( Ulmus procera) are to be found within the gen- eral area of the sightings. False nettle {Boehemia) does not occur in Newfoundland. Of the five species or subspecies of the genus Poly- gonia currently found in Newfoundland, only the Green Comma {) is reasonably common. All others are uncommon and not readily identifiable in the field. Both hops and Stinging Nettle are to be found in many Newfoundland outports, especially on the Avalon Peninsula, having originated with the early settlers. English Elm trees also are scattered and well established throughout the city of St. John's. There- fore, in areas where one or more of its host plants are present, the Hop Merchant could occur at a low popu- lation level similar to that of other recorded Polygo- nia. Its apparent anonymity could largely be due to the scarcity and difficulty in identifying members of this genus and to the lack of experienced field observers in the area.
