The motivation for this survey was to determine the presence-absence of the wandering skippering in five other lagoons and gather a relative abundance where they were found.
The wandering skipper (Panoquina errans) is a small butterfly of the family Hesperiidae. It is identifiable by its rich dark brown color and cream-colored spots on the dorsal forewing. The wandering skipper is found only along the coast in southern California, Baja California and northwestern mainland Mexico. Populations have been recorded from Huntington Beach, Upper Newport Bay, and Capistrano Beach. In San Diego, the wandering skipper has been documented in the Tijuana Estuary, San Dieguito Lagoon, and Agua Hedionda lagoon, but it appears that no extensive survey data have been published. The five lagoons surveyed were San Elijo, Los Penasquitos, Kendall-Frost, Famosa Slough, and Sweetwater marsh. Butterflies were detected using a Pollard walk with two observers moving along a line through potential habitat. Binoculars were used to aid visual identification. A handheld GPS unit was used to record the location of each individual detected; photos were taken when possible to confirm identification. Salt grass patches were also recorded using a handheld GPS device. Surveys were conducted in August through September of 2010 between the hours of 10am and 3pm. Temperature, wind speed, and cloud cover were recorded. This datalayer is a point file containing observations of the wandering skipper. Each of the 170 points represents an individual observation. The surveys were conducted by San Diego Associatation of Governments (SANDAG) staff and others.
