Spotting Butterflies Says Ulsh New & Features “A butterfly’s lifespan generally cor- responds with the size of the butterfly,” Spotting Butterflies says Ulsh. The tiny blues often seen in the mountains generally only live about How, when and where to find Lepidoptera in 10 days. Some species, however, will the Cascades and Olympics overwinter in the egg, pupa or chrysalid form (in the cocoon prior to becoming winged adults). A few Northwest spe- cies overwinter as adults, and one—the mourning cloak—lives for ten months, and is the longest lived butterfly in North America. The first thing that butterflies do upon emerging from the chrysalis and unfold- ing their wings is to breed. In their search for mates, some butterflies “hilltop,” or stake out spots on high trees or ridgelines to make themselves more prominent. A butterfly’s wing colors serve two distinct purposes. The dorsal, or upperside of the wings, are colorful, and serve to attract mates. The ventral, or underside of the wings generally serves to camouflage the insects. So a butterfly such as the satyr comma has brilliant orange and yellow Western tiger and pale tiger swallowtail butterflies “puddling.” When looking for for spots when seen with wings open, and butterflies along the trail keep an eye on moist areas or meadows with flowers. a bark-like texture to confuse predators when its wings are closed.

    256 JOURNAL OF THE LEPIDOPTEHISTS' SOCIETY INCISALIA FOTIS SCHRYVERI (LYCAENIDAE): BIONOMIC NOTES AND LIFE HISTORY CLIFFORD D. FERRIS University of Wyoming, Laramie and RAY E. STANFORD Denver, Colorado In the years that have elapsed since the original description of Incisalia fotis schryveri Cross (1937), little additional information has been gath­ ered regarding the biology of the insect. The distributional limits have been imprecisely determined, the immature stages have remained un­ described, and only vague speculation has appeared regarding possible host plants. This paper constitutes the first description of the immature stages and a record of the host plant. The insect was studied in Wyoming (by Ferris) and in Colorado (by Stanford). In the paragraphs which follow, where regional differences exist, state names will bc mentioned; otherwise descriptions pertain to the entire range of schryveri. Ecology and Nature of Habitat Incisalia fotis schryveri occurs in multiplc colonies in the eastern foot­ hills of the Front Range of the Rocky Mountains in north-central Colo­ rado, and in the continuation of this range into south-eastern Wyoming. Its northern limits, or possible blend zones with I. fotis mossii (H. Edwards), have yet to be determined, but in Colorado it seems to ex­ tend no farther south than El Paso Co. Rccords are also available from Boulder, Clcar Creek, Douglas, Gilpin, and Larimer Cos. The species probably occurs also in thc northeast portion of Park Co., along the Platte River, and may be found in parts of Teller Co. In Wyoming, it is known from Albany, Carbon, and Converse Cos., and is associated with the Laramie, North Platte, and Platte Hiver drainages.

    Summary of: Surveys for Seaside Hoary Elfin ( Incisalia polia maritima ) and Insular Blue Butterfly ( Plebejus saepiolus littoralis ) at North Spit ACEC and New River ACEC Holly F. Witt, Wildlife Biologist Madeleine Vander Heyden, Wildlife Biologist Bureau of Land Management Coos Bay District North Bend, Oregon 31 August 2006 During the summer of 2006, surveys for Seaside Hoary Elfin ( Incisalia polia maritima ) and Insular Blue Butterfly ( Plebejus saepiolus littoralis ) were conducted at North Spit ACEC and New River ACEC in Coos County, Oregon on lands administered by the Coos Bay District of the Bureau of Land Management. The surveys were conducted by Dana Ross of Corvallis, Oregon, under a contract funded through the Oregon/Washington BLM & Region 6 Forest Service Interagency Special Status/Sensitive Species Program (ISSSSP). This document incorporates the report of survey methods and results Dana submitted to Coos Bay BLM. The Seaside Hoary Elfin ( Incisalia polia maritima ) and Insular Blue Butterfly (Plebejus saepiolus littoralis ) have an extremely limited (maritime) range and are known from only a few historical sites. Coos Bay BLM is within the range of both species and contains habitat suitable for their presence. Identification of these butterflies requires an expert familiar with local species. Both species are listed as Bureau Sensitive within Oregon by the BLM special status species program. BLM 6840 - Special Status Species Management policy objectives are: To ensure that actions requiring authorization or approval by the Bureau of Land Management (BLM or Bureau) are consistent with the conservation needs of special status species and do not contribute to the need to list any special status species, either under provisions of the ESA or other provisions of this policy.

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.
