Discussion | Eucnide lobata is known in the flora area from Starr County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eucnide urens is found primarily in the Mojave Desert but extends into surrounding areas. Asydates inyoensis, soft-wing flower beetles of the family Melyridae, have been found in flowers of E. urens; they collect pollen on dorsal setae and likely serve as pollinators.
