Red Admiral
Before Europeans arrived on the scene, red admiral butterflies used stinging nettle, as pictured below.
Most stinging nettle has been removed. Although it is supposed to have healing properties, people don't like being stung, so they get rid of it. Now Red Admirals are more likely to use a common weed, pellitory, pictured below. Or hops, the picture below the stinking nettle. (host plant)
