We recommended no change in status. http://ecos.fws.gov/docs/five_year_review/doc2518.pdf (Latest info on this species.) DESCRIPTION The callippe (ca-LIP-ee) silverspot is a medium-sized butterfly in the brush foot family (Nymphalidae). It has a wingspan of about 5.5 centimeters (2.2 inches). The upper wings are brown with extensive black spots and lines, and the basal areas are extremely dark. The undersides are brown, orange-brown and tan with black lines and distinctive black and bright silver spots. The basal areas of the wings and body are densely hairy. The caterpillars are dark- colored with many branching sharp spines on their backs. Identification of the subspecies is challenging in some parts of its range because it can hybridize with Lilian’s and Comstock’s silverspot butterflies, producing offspring that are intermediate in appearance. Life History and Ecology The callippe silverspot butterfly has one flight of adults per year. It undergoes complete metamorphosis (a structural transformation during the development of an organism) from egg to larval, pupal and adult stages. Egg Stage During the early summer flight season, females lay their eggs on the dry remains of the larval food plant, Johnny jump-up ( Viola pedunculata ), or on the surrounding debris.

    Effect of different grazing regimes on Viola pedunculata populations at King Ranch - 2010 December 16, 2010 Prepared by: Elizabeth Bernhardt Tedmund Swiecki Prepared for: Sue Wickham Solano Land Trust 1001 Texas Street, Ste C Fairfield, CA 94533 P HYTOSPHERE R ESEARCH 1027 Davis Street, Vacaville, CA 95687-5495 707-452-8735 email: [email protected] URL: http://phytosphere.com 2010 - King Ranch V. pedunculata grazing study Page 2 of 16 SUMMARY This report discusses second year results of a study that investigates how specific changes to the grazing regime at King Ranch affects cover of Viola pedunculata, the larval food plant of the Callippe silverspot butterfly. In 2007, we established plots in six clusters of three plots each at widely spaced locations on the ranch, with three clusters on each of two common soil types. Cover in these plots was read in spring 2007 and 2008 to serve as a baseline. One plot in each cluster was excluded from grazing early in the grazing season in 2009 and 2010. A second plot in each cluster was excluded from grazing late in the season in 2009 and 2010. The plots excluded from grazing did not differ in V. pedunculata cover or grass cover compared to plots which had not been excluded from grazing. Although grass cover and vegetation height were negatively correlated with V. pedunculata cover, excluding plots from grazing for short periods did not result in V. pedunculata cover differences. Vegetation height and cover were correlated with precipitation during the growing season. Due to the interactions that exist between grazing impacts and weather, we recommend that the study be continued for at least two to three more years, so that treatment effects can be assessed over a wider range of weather conditions.

  • 3.4 Biological Resources for the Purpose of This EIR, Biological Resources Comprise Vegetation, Wildlife, Natural Communities, and Wetlands and Other Waters
    Impact Analysis Alameda County Community Development Agency Biological Resources 3.4 Biological Resources For the purpose of this EIR, biological resources comprise vegetation, wildlife, natural communities, and wetlands and other waters. Potential biological resource impacts associated with the program and the two individual projects are analyzed. Potential impacts are described quantitatively and qualitatively in Section 3.4.2, Environmental Impacts. This section also identifies specific and detailed measures to avoid, minimize, or compensate for potentially significant impacts on biological resources, where necessary. 3.4.1 Existing Conditions Regulatory Setting Federal Endangered Species Act Pursuant to the federal Endangered Species Act (ESA), USFWS and the National Marine Fisheries Service (NMFS) have authority over projects that may result in take of a species listed as threatened or endangered under the act. Take is defined under the ESA, in part, as killing, harming, or harassing. Under federal regulations, take is further defined to include habitat modification or degradation that results, or is reasonably expected to result, in death or injury to wildlife by significantly impairing essential behavioral patterns, including breeding, feeding, or sheltering. If a likelihood exists that a project would result in take of a federally listed species, either an incidental take permit, under Section 10(a) of the ESA, or a federal interagency consultation, under Section 7 of the ESA, is required. Several federally listed species—vernal pool fairy shrimp (Branchinecta lynchi), longhorn fairy shrimp (Branchinecta longiantenna), vernal pool tadpole shrimp (Lepidurus packardi), California tiger salamander (Ambystoma californiense), California red‐legged frog (Rana draytonii), Alameda whipsnake (Masticophis lateralis euryxanthus), and San Joaquin kit fox (Vulpes macrotis mutica)—have the potential to be affected by activities associated with the Golden Hills and Patterson Pass projects as well as subsequent repowering projects.

  • Details of Important Plants in Rpbg
    DETAILS OF IMPORTANT PLANTS IN RPBG ABIES BRACTEATA. SANTA LUCIA OR BRISTLECONE FIR. PINACEAE, THE PINE FAMILY. A slender tree (especially in the wild) with skirts of branches and long glossy green spine-tipped needles with white stomatal bands underneath. Unusual for its sharp needles and pointed buds. Pollen cones borne under the branches between needles; seed cones short with long bristly bracts extending beyond scales and loaded with pitch, the cones at the top of the tree and shattering when ripe. One of the world’s rarest and most unique firs, restricted to steep limestone slopes in the higher elevations of the Santa Lucia Mountains. Easiest access is from Cone Peak Road at the top of the first ridge back of the ocean and reached from Nacimiento Ferguson Road. Signature tree at the Garden, and much fuller and attractive than in its native habitat. ACER CIRCINATUM. VINE MAPLE. SAPINDACEAE, THE SOAPBERRY FAMILY. Not a vine but a small deciduous tree found on the edge of conifer forests in northwestern California and the extreme northern Sierra (not a Bay Area species). Slow growing to perhaps 20 feet high with pairs of palmately lobed leaves that turn scarlet in fall, the lobes arranged like an expanded fan. Tiny maroon flowers in early spring followed by pairs of winged samaras that start pink and turn brown in late summer, the fruits carried on strong winds. A beautiful species very similar to the Japanese maple (A. palmatum) needing summer water and part-day shade, best in coastal gardens. A beautiful sight along the northern Redwood Highway in fall.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. We describe a rearing protocol that allowed us to raise the threatened butterfly, Argynnis diana (Nymphalidae), while bypassing the first instar overwintering diapause. We compared the survival of offspring reared under this protocol from field-collected A. diana females from North Carolina, Georgia, and Tennessee. Larvae were reared in the lab on three phylogenetically distinct species of Southern Appalachian violets (Viola sororia, V. pubescens,andV. pedata). We assessed larval survival in A. diana to the last instar, pupation, and adulthood. Males reared in captivity emerged significantly earlier than females. An ANOVA revealed no evidence of host plant preference by A. diana toward three native violet species. We suggest that restoration of A. diana habitat which promotes a wide array of larval and adult host plants, is urgently needed to conserve this imperiled species into the future. 1.

(SUBGENUS SPEYERIA) (NYMPHALIDAE) FROM WASHINGTON DAVID G. JAMES Department of Entomology, Washington State University, Irrigated Agriculture Research and Extension Center, 24105 North Bunn Road, Prosser, Washington 99350; email: [email protected] ABSTRACT. Comparative illustrations and notes on morphology and biology are provided on the immature stages of five Arg- ynnis spp. (A. cybele leto, A. coronis simaetha, A. zerene picta, A. egleis mcdunnoughi, A. hydaspe rhodope) found in the Pacific Northwest. High quality images allowed separation of the five species in most of their immature stages. Sixth instars of all species possessed a fleshy, eversible osmeterium-like gland located ventrally between the head and first thoracic segment. Dormant first in- star larvae of all species exposed to summer-like conditions (25 ± 0.5º C and continuous illumination), 2.0–2.5 months after hatch- ing, did not feed and died within 6–9 days, indicating the larvae were in diapause. Overwintering of first instars for ~ 80 days in dark- ness at 5 ± 0.5º C, 75 ± 5% r.h. resulted in minimal mortality. Subsequent exposure to summer-like conditions (25 ± 0.5º C and continuous illumination) resulted in breaking of dormancy and commencement of feeding in all species within 2–5 days. Durations of individual instars and complete post-larval feeding development durations were similar for A. coronis, A. zerene, A. egleis and A.

  • Alameda Whipsnake: the Fasttest Snake in the West by Mike Westphal
    Alameda Whipsnake: The Fasttest Snake in the West by Mike Westphal A narrow footpath circles the crest of Mt. Diablo. The sunlight comes early to this high place and in May will warm the rocky soil around the manzanita bushes early in the morning, once the fog has burned away. If you were a snake - a fast snake, a snake that hunted lizards by day - you would live in a place like this, a place among the shrubbery where you could heat up and go. If you, on the other hand, up and go. If you, on the other hand, were a person and Photo by Sheila Larsen / USFWS wanted to pay a call on the Alameda whipsnake, you might also come here. A simple wooden rail follows the footpath on the downhill side. Walk slowly along the rail and watch the ground. Be quiet and alert. The Alameda whipsnake does not wait. If it sees you and doesn’t want to hang around, it will be gone before you even know what you’re looking at. If you are careful enough, you may see a rare and beautiful snake - a snake built for speed. Its body is long (to six feet) annd whiplike (hence the name). The neck is slender, topped with a darting head that houses the big eyes of a visual predator. In color, it is the deep, deep green traditional to British racecars; it is detailed on either side with a bold orange stripe. The whipsnake is polished and glossy in the morning sun. Stare at it as long as you can, for this is no "sit-and-wait" predator, and will soon move away to chase down a fat lizard for breakfast.
