Using the unusually well-documented butterfly fauna of Davis, Yolo County, Califor- nia, it is shown that the mainly native species commonly observed in gardens breed mostly or entirely on alien plants, especially naturalized weeds. Over 40% of the fauna has no known native hosts in the urban-suburban environment. Were certain alien weeds to be eradicated or their abundance greatly reduced, the urban-suburban butterfly fauna would disappear. This might be regarded as an unfortunate, and perhaps… Expand
Exotics as host plants of the California butterfly fauna
Impacts of introduced plant taxa on California's butterflies are expected to increase as both habitat conversion and alien introductions accelerate. Expand
Lepidoptera-habitat relationships in urban parks
Several plant species received heavy use and appeared to be important to Lepidoptera in this urban environment, particularly butterfly-bush (Buddleia davidii), mugwort (Artemisia vulgaris), knapweed, and clover (Trifolium spp.). Expand
Relative importance of habitat and landscape scales on butterfly communities of urbanizing areas.
This study investigates butterfly communities of four land-use types within different landscape contexts and reveals that variations in structure and functional composition of these communities are related to different levels of human disturbance at both landscape scale and habitat scale. Expand
