Hi - Horseweed is a host plant for various species of moths, and various bees and flies feed on the nectar. https://www.marylandbiodiversity.com/viewSpecies.php?species=4245
Refer to the following page and see the section on fauna associations, https://www.illinoiswildflowers.info/weeds/plants/horseweed.htm.
This plant spreads easily by seeds and can become problematic. If you decide not to keep it, it is easy to pull up by hand.
