No change recommended. www.fws.gov/ecos/ajax/docs/five_year_review/doc3216.pdf Mission Blue Butterfly (285 KB) David Wright, USFWS DESCRIPTION The mission blue ( Icaricia icarioides missionensis ) is a small, delicate butterfly in the Lycaenidae (gossamer-winged butterfly) family. 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.

  • The Consequences of a Management Strategy for the Endangered Karner Blue Butterfly
    THE CONSEQUENCES OF A MANAGEMENT STRATEGY FOR THE ENDANGERED KARNER BLUE BUTTERFLY Bradley A. Pickens A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August 2006 Committee: Karen V. Root, Advisor Helen J. Michaels Juan L. Bouzat © 2006 Bradley A. Pickens All Rights Reserved iii ABSTRACT Karen V. Root, Advisor The effects of management on threatened and endangered species are difficult to discern, and yet, are vitally important for implementing adaptive management. The federally endangered Karner blue butterfly (Karner blue), Lycaeides melissa samuelis inhabits oak savanna or pine barrens, is a specialist on its host-plant, wild blue lupine, Lupinus perennis, and has two broods per year. The Karner blue was reintroduced into the globally rare black oak/lupine savannas of Ohio, USA in 1998. Current management practices involve burning 1/3, mowing 1/3, and leaving 1/3 of the lupine stems unmanaged at each site. Prescribed burning generally kills any Karner blue eggs present, so a trade-off exists between burning to maintain the habitat and Karner blue mortality. The objective of my research was to quantify the effects of this management strategy on the Karner blue. In the first part of my study, I examined several environmental factors, which influenced the nutritional quality (nitrogen and water content) of lupine to the Karner blue. My results showed management did not affect lupine nutrition for either brood. For the second brood, I found that vegetation density best predicted lupine nutritional quality, but canopy cover and aspect had an impact as well.

  • The Radiation of Satyrini Butterflies (Nymphalidae: Satyrinae): A
    Zoological Journal of the Linnean Society, 2011, 161, 64–87. With 8 figures The radiation of Satyrini butterflies (Nymphalidae: Satyrinae): a challenge for phylogenetic methods CARLOS PEÑA1,2*, SÖREN NYLIN1 and NIKLAS WAHLBERG1,3 1Department of Zoology, Stockholm University, 106 91 Stockholm, Sweden 2Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Av. Arenales 1256, Apartado 14-0434, Lima-14, Peru 3Laboratory of Genetics, Department of Biology, University of Turku, 20014 Turku, Finland Received 24 February 2009; accepted for publication 1 September 2009 We have inferred the most comprehensive phylogenetic hypothesis to date of butterflies in the tribe Satyrini. In order to obtain a hypothesis of relationships, we used maximum parsimony and model-based methods with 4435 bp of DNA sequences from mitochondrial and nuclear genes for 179 taxa (130 genera and eight out-groups). We estimated dates of origin and diversification for major clades, and performed a biogeographic analysis using a dispersal–vicariance framework, in order to infer a scenario of the biogeographical history of the group. We found long-branch taxa that affected the accuracy of all three methods. Moreover, different methods produced incongruent phylogenies. We found that Satyrini appeared around 42 Mya in either the Neotropical or the Eastern Palaearctic, Oriental, and/or Indo-Australian regions, and underwent a quick radiation between 32 and 24 Mya, during which time most of its component subtribes originated. Several factors might have been important for the diversification of Satyrini: the ability to feed on grasses; early habitat shift into open, non-forest habitats; and geographic bridges, which permitted dispersal over marine barriers, enabling the geographic expansions of ancestors to new environ- ments that provided opportunities for geographic differentiation, and diversification.

Less than 1% of historic Fender’s habitat remains and much of that has been degraded by invasive grasses and forbs. To date, research involving Butte is surprising, especially considering Lasius alienus was the habitat restoration for Fender's blue has focused primarily on how invasive vegetation affects the adult dominant tending species and exhibited an expected pattern in stage, but recent work suggests ant tending may significantly increase survivorship in Fender's blue larvae, resulting in a higher population growth rate. Fender's blue, like ~45% of all lycaenids, maintains a previous work at Baskett Slough NWR, OR [2] facultatively mutualistic relationship with ants. Our work indicates that Fender's blue larvae are tended by at least six ant species in as many genera.

Here, we investigate the role of biogeography and the evolution of ecological traits on the diversification of the Holarctic arcto-alpine butterfly genus Oeneis (Lepidoptera: Satyrinae). We reconstructed the molecular phylogeny of the genus based on one mitochondrial (COI) and three nuclear (GAPDH, RpS5, wingless) genes. We inferred the biogeographical scenario and the ancestral state reconstructions of climatic and habitat requirements. Within the genus, we detected five main species groups corresponding to the taxonomic division and further paraphyletic position of Neominois (syn. n.). Next, we transferred O. aktashi from the hora to the polixenes species group on the bases of molecular relationships. We found that the genus originated in the dry grasslands of the mountains of Central Asia and dispersed over the Beringian Land Bridges to North America several times independently.
