We believe this is a member of the superfamily Pyraloidea, which includes the families Pyralidae and Crambidae, but we are not having any luck identifying the species. We do not believe it poses a threat to your hemp plant. Perhaps one of our readers will have better luck with an identification than we have had.
Update: June 11, 2019
Thanks to a comment from Karl, we now know that this is a Sparganothis Fruitworm Moth, Sparganothis sulfureana, a Tortricid Moth in the family Tortricidae, a new category for our site. According to BugGuide: “Larvae feed on a variety of forbs and woody plants, including some crops, such as corn (maize) and cranberry.” Tortricids of Agricultural Importance does not list Cannabis as a host plant, but it is surely a woody plant and we will have to retract our earlier statement about it not posing a threat to Benjamin’s hemp plant. It might pose a threat.
Very interesting! Even in an area where blueberries (apparently a pest of cranberry and blueberries) are abundant I have never heard of this species before. It seems to be polyphagus so I will keep my eye out for damage to the hemp. I suspect it will not prefer to reproduce on the hemp so it will migrate but time will tell Thank you for the update
