U.S. Fish & Wildlife Service Butterflies Bill Williams River National Wildlife Refuge Butterflies at Bill Williams River NWR The Bill Williams River National Wildlife Refuge supports the last and largest remnant of the native riparian habitats that once filled the valleys of the lower Colorado River and its tributaries. These now unique habitats support many butterfly species. A total of 34 species have been documented in the refuge, 11 (32%) of which were found only here in a recent study (Nelson and Andersen 1998). One species, MacNeill’s sootywing skipper, is of some concern to conservationists due to its rarity. The larvae apparently only feed on one species of saltbush (Atriplex lentiformis), a native shrub of the lower Colorado River valley. Wiesenborn (1997) often observed adults flying between the saltbush and honey mesquite (Prosopis glandulosis).
