Golden drifts of beggar's ticks add late-summer color to the landscape. The name, beggar's tick, refers to the seed shape. The achene has stiff awns that are barbed with two teeth-like structures which can easily latch onto humans or animals. This is a type of seed dispersal referred to as "hitchhiking". The caterpillars of the butterfly Nathalis iole (Dainty Sulfur) are known to favor the foliage of Bidens spp. as a food source and the seeds are popular with Bobwhite and Purple and Goldfinches. | This is one of the prettier and more drought tolerant Bidens spp. It blooms in marshes, meadows and bogs throughout North Carolina from August to October.
