January-February 2002 U.S. Fish & Wildlife Service The writer Wallace Stegner, who served as Assistant Secre­ tary of the Interior in the Kennedy Administration, once called national parks “the best idea we ever had. Absolutely American, abso­ lutely democratic, they reflect January/February 2002 Vol. XXVII No. 1 us at our best....” Since Yellow- stone National Park was established in 1872, the Na­ tional Park System has grown to encompass 83 million acres (34 million hectares) in 385 areas within 49 States, the District of Columbia, Ameri­ can Samoa, Guam, Puerto Rico, Saipan, and the U.S. Virgin Islands. Its mission is “to preserve unimpaired the natural and cultural re- sources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations.” Conserving endangered species is an important part of that mission.

Wingspan is about 2.5 to 3.6 centimeters. (1 to 1.5 inch). The upper wing surfaces of the male are iridescent blue and lavender with black margins fringed with long white hair-like scales. There are no spots on the upper surfaces of the wings. In males, the ventral surfaces of the wings are whitish with small circular gray spots in the submarginal areas and larger circular black spots located in post-median and submedian areas of the fore and hind wings. The body of the male is dark bluish brown. Females have dark brown upper wing surfaces marked with blue basal areas. The margins and wing fringe are similar to the male. Female underwings are stone gray with a dot pattern similar to the males'. The adult flight season extends from late March to early July, depending on the location and microclimatic conditions. Females lay eggs throughout the mating flight.

  • A Survey of the Grasslands of The
    A Survey of the Grasslands of the Northeast Ridge (Guadalupe Hills) as Habitat for the Mission Blue Butterfly (Icaricia icarioides missionensis) and the Callippe Silverspot (Speyeria callippe callippe) For San Bruno Mountain Watch 44 Visitacion Avenue Brisbane, California 94005 May 14, 2007 By Thomas Y. Wang Biologist San Francisco, California Introduction The Mission Blue butterfly Icaricia icarioides missionensis and Callippe Silverspot Speyeria callippe callippe are two endangered butterfly species that live on San Bruno Mountain. The U.S. Fish and Wildlife Service listed the Mission Blue in 1976 (New 1993), and the Calllippe Silverspot was listed in 1997 (USFWS 2007). Both have a restricted range due mainly to urbanization and their particular ecology. The Mission Blue butterfly lays eggs only on several species of lupines, and has an association with specific ant species for a part of its lifecycle (Cushman and Murphy 1993). The Callippe Silverspot also has a restricted host plant – Viola pedunculata. It oviposits in the vicinity of Viola pedunculata (Thomas Reed Associates 1982) or on them (Arnold 1981). The host plants for both butterflies are plants of the grasslands – a scarce plant community of the Franciscan peninsula due to urbanization. The Habitat Conservation Plan of 1983 allowed for take of Mission Blue lands in exchange for land preserved elsewhere and restoration of butterfly habitat. Parts of the Northeast Ridge became the San Bruno Mountain County and State Park. Other parts of it were slated for development and miscellaneous open space. As part of the Habitat Conservation Plan, mark-release-recapture studies were performed on the Callippe Silverspot and the Mission Blue.

Sacramento Fish and Wildlife Field Office U.S. Fish and Wildlife Service Sacramento, California February 2010 5-YEAR REVIEW San Bruno Elfin Butterfly (Callophrys mossii bayensis) and Mission blue butterfly (Icaricia icarioides missionensis) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed.

Because pardalis phenotypes effectively surround the original distribution of I. i. pheres (now extinct in San Francisco), the subspecies I. i. missionensis may well be polyphylectic in origin, having arisen independently north and south of the center of I. i. pheres distribution. Thus the present "continuous" distribution of the Mission blue is an artifact of the disappearance of I. i. pheres. This taxon may be identified by comparison with illustrations of Icaricia (Plebejus) icarioides missionensis on Plate 59 (Fig.1 and 2) of "The butterflies of North America" (03).

University of Southern California GIS Research Laboratory and Center for Sustainable Cities, Los Angeles, Cali- fornia. Introduction The butterfly monitoring scheme for the San Bruno Mountain Habitat Conservation Plan from 1982 to 2000 was plagued with a number of methodological difficulties. These included a haphazard rather than random survey design, no repeatability between years, and varying geographic coverage. While some information can be extracted from the “wandering surveys” conducted on San Bruno Mountain, a more rigorous survey design is necessary to allow managers to draw statistically significant inferences about the status of the butterflies and their responses to management actions. Indeed, since 1998, standardized transects have been established to monitor butterflies at San Bruno Mountain. This report discusses the factors that should be considered in the further development of a new monitoring protocol. While it provides as detailed guidance as possible, the ultimate survey design must incorporate the considerations of those who will imple- ment the surveys. Feasibility on paper does not always translate well to the field. This report draws on the analysis of mission blue butterfly and Callippe silverspot but- terfly survey data completed by USC.

  • Mission Blue Butterfly Habitat Restoration in the Golden Gate National Recreation Area
    National Park Service U.S. Department of the Interior San Francisco Bay Area Network Inventory and Monitoring Program Resource Brief February 2011 Mission Blue Butterfly Habitat Restoration in the Golden Gate National Recreation Area Importance: Maintaining healthy grassland ecosystems is critical to the continued survival of the federally endangered mission blue butterfly in the Golden Gate National Recreation Area (GGNRA). Mission blue butterfly habitat consists of coastal grassland or a mix of coastal grassland and scrub where silver lupine (Lupinus albifrons var. collinus), summer lupine (Lupinus formosus) or varied lupine (Lupinus variicolor) are present. These three species are the only plants that mission blue caterpillars can eat, though silver lupine is the mission blue’s preferred host plant. Adult butterflies must lay their eggs on one of these lupines so Above: Mission blue they cannot stray far. butterfly habitat dotted with lupines in the Unfortunately, vast portions of mission blue habitat have already Marin Headlands.

These habitat patches are threatened by invasions of non-native trees and other plants and by a lack of natural disturbances such as historic elk grazing and wildfires that would normally prevent scrubland from taking over. French broom, (Genista monspessulana), Pampas grass (Cortaderia jubata and C. pampas ), Cape ivy (Delairea odorata), and thoroughwort (Ageratina adenophora) are some of the invasive plants that commonly threaten mission blue habitat in the GGNRA.

    Survey of the endangered Mission blue butterfly in the Marin Headlands Spring 2008 Susie Bennett Golden Gate National Parks Conservancy 201 Fort Mason San Francisco, CA 94123 SUMMARY 2008 Field Season In the spring of 2008, seventeen permanent transects distributed among five monitoring regions in the Marin Headlands (north of San Francisco) were monitored for Mission blue butterflies. Weather permitting, surveys were performed every 7 to 10 days from February 25, 2008 through June 6, 2008. Thirteen surveys were completed during this time frame, and Mission blue butterflies were seen on six of the thirteen surveys. During the surveys, 40 Mission blues were observed on transects and 107 were seen off transect. Locations of butterflies seen off transect were recorded using a handheld GPS device whenever possible. The first adult Mission blue observed during these surveys was seen on March 26, 2008 and the last observed butterfly was seen on May 16, resulting in a 52 day flight season. Most butterflies were observed early in the flight season, with a peak of 22 butterflies seen on transect (88 on and off transect) observed in a single day (on and off transect) on April 11. Males comprised 72% of the transect observations and 64% of off transect observations. Several pairs of butterflies were observed interacting, including four instances of male-male interactions, two instances of apparent courting between males and females, and one observation of a male and a female mating. Mission blue butterflies were observed at four of the five monitoring regions. No butterflies were seen at Battery Duncan and only one butterfly was seen at Wolfback Ridge.

  • Progress Report for the Mission Blue Butterfly (Icaricia Icarioides Missionensis) at Twin Peaks Natural Area
    Progress Report For The Mission Blue Butterfly (Icaricia icarioides missionensis) At Twin Peaks Natural Area Stuart B. Weiss, Ph.D. Christal Niederer Creekside Center for Earth Observation Lisa Wayne Kirra Swenerton San Francisco Recreation and Park Department November 8 , 2012 Executive Summary In May 2012, a total of 11 female and 5 male Mission blue butterflies were transferred from San Bruno Mountain to Twin Peaks Natural Area. These butterflies were used to supplement the existing small population, and to further reintroduction efforts from 2009 and 2011. Both post diapause larvae and adult butterflies were noted at Twin Peaks before the additional butterflies were translocated, indicating success from the previous releases. The number of adults translocated was below our permitted quota of 40 females and 20 adults. Adults were difficult to find this year at San Bruno Mountain. Butterfly numbers were down at some other sites, and high winds and fog limited success on scheduled field days. A new collection protocol was initiated, which increased collection area and streamlined capture time, while preventing overcollecting. As in previous years, all butterflies were released on a robust Lupinus albifrons or L. variicolor host plant the same day at Twin Peaks. In many cases, butterflies were released under a mesh enclosure attached to the lupine, in order to encourage oviposition and to prevent butterflies from leaving the site. On cool days, when butterflies were inactive, this step was skipped to minimize handling. Adults were again released at Mission Ridge and Gardenside. No releases were made at Mission Flats based on low number of released individuals this year, and high numbers of releases there in previous years.
