Proximate Constraints On Intruder Detection In The Dragonfly Perithemis Tenera (Odonata: Libellulidae): Effects Of Angle Of Approach And Background, Paul Switzer, Perri Eason

Faculty Research & Creative Activity

The implications of insects’ vision for territorial defense have been relatively little studied in the field. In the dragonfly Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intruders were directly in front of them; they also detected more intruders in front of them than from other angles. Intruders viewed against distant vegetation were detected more readily than were intruders against near vegetation. Residents detected more intruders …

A New Elfin Butterfly (Lycaenidae: Eumaeini) From Northern China With Comments On The Nomenclature Of Palaearctic Elfins, Kurt Johnson

The Taxonomic Report of the International Lepidoptera Survey

Ahlbergia hsui, new species, is described from two specimens recently collected in China’s Nan Shan area of endemism located along the boundary of northern China with Mongolia. In discussing the new species, the historical literature concerning Palaearctic elfin butterflies is reviewed and compared to nomenclatorial usages in D’Abrera’s widely disseminated 1993 treatment of Palaearctic butterflies; 25 errors or omissions in the latter treatment are corrected.

Salinity And Shade Preferences Result In Ovipositional Differences Between Sympatric Tiger Beetle Species, W. Wyatt Hoback, Douglas A. Golick, Tina Marie Svatos, Stephen M. Spomer, Leon G. Higley

Department of Entomology: Faculty Publications

1. Adult tiger beetles of the genus Cicindela often co-occur within a habitat but larvae do not. Larvae are sedentary and form usually permanent burrows at the site of oviposition where they require 1-3 years for development.

2. To test niche partitioning based on ovipositional preference, the behavior of two sympatric salt marsh tiger beetles, Cicindela circumpicta and C. togata (Coleoptera: Cicindelidae), were examined.

3. In laboratory studies, female C. circumpicta and C. togata distinguished between experimental salinities, with the former preferring 4 parts per thousand (ppt) and the latter preferring 12 ppt. In the field, C. circumpicta larvae were …

Celastrina Idella (Lycaenidae: Polyommatinae): A New Butterfly Species From The Atlantic Coastal Plain, David M. Wright, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

A new species of Polyommatinae, Celastrina idella, is described from the sandy Atlantic coastal plain of the eastern United States. It is presently known to occur from southern New Jersey through Georgia. Celastrina idella larvae have been recorded from four species of Ilex (holly). Celastrina idella is distinguished from sympatric C. ladon and C. neglecta by differences in larval host, flight period, pupal diapause, and adult size and wing characters. In the New Jersey pine barrens the butterfly is univoltine and flies in the spring between the flights of its sympatric congeners.

Hübner’S Helicta, The Forgotten Neonympha: The Recognition And Elevation Of Neonympha Helicta (Nymphalidae: Satyrinae) To Specific Status, The Designation Of Neotypes For N. Helicta And N. Areolatus, The Subspecific Transfer Of Septentrionalis To Helicta And The Description Of A Third Helicta Subspecies From South Florida, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Hübner (1806) based the name Oreas fimbriata helicta on a John Abbot painting of a southeastern United States satyr without a written description. Subsequent lepidopterists have nearly ignored this taxon. Helicta is herein recognized as a valid species–Neonympha helicta. A neotype is designated for helicta from Aiken County, South Carolina and deposited in the Allyn Museum of Entomology Sarasota, Florida. A neotype is also designated for Papilio areolata J.E. Smith, 1797 from Chatham County, Georia and deposited in the Allyn Museum of Entomology. Septentrionalis Davis, 1924 is recognized as the northern United States subspecies of helicta not areolatus …

A New Subspecies Of Brephidium Isophthalma (Lycaenidae: Polyommatinae) From Coastal South Carolina, Harry Pavulaan, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Brephidium isophthalma pseudofea was described in 1873 from the Florida Keys, United States. The ventral ground color of the wings in topotypical pseudofea is a yellowish brown. The antennal clubs of pseudofea have prominent orange red tips. The ventral surface of the abdomen of pseudofea is broadly white to very light gray and usually extends halfway around the sides of the light to medium brown abdomen. Specimens of B. isophthalma from coastal South Carolina differ greatly from topotypical pseudofea. Accordingly, B. i. insularus is described as a new subspecies from coastal South Carolina. The antennal clubs …

A Comment On Friedlander’S Asterocampa (Nymphalidae, Apaturinae): Designation Of Neotypes For A. Celtis And A. Clyton, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Friedlander’s 1986 [1987] treatment of the southeastern United States. taxa of Asterocampa is examined. Neotypes of A. celtis and A. clyton are designated from Burke County, Georgia to help stabilize the status of these taxa and aid in any future research. Asterocampa celtis is currently known to exist within at least 40 km of A. c. reinthali in Georgia. Their proximity, without integration, suggests evolutionary distance, perhaps even speciation. It is proposed that A. celtis is descended from A. c. alicia, and alicia from a Mexican refugium. Asterocampa clyton and A. …

The Taxonomic Report of the International Lepidoptera Survey

Megathymus cofaqui and M. yuccae are both represented in the southeastern United States by two subspecies. The type locality of both M. y. yuccae and M. c. cofaqui is the area of Burke/Screven counties Georgia. Each of their subspecies are primarily Floridian, with M. y. buchholzi extending along the immediate coast of Georgia into southern South Carolina. Topotypes of M. cofaqui from Burke County, Georgia, and Aiken County, South Carolina are phenotypically indistinguishable from both the holotype of M. cofaqui and topotypes of M. c. harrisi. Thus, M …

Plant Hybrid Zones And Insect Host Range Expansion, Diana Pilson

Diana Pilson Publications

The hybrid bridge hypothesis suggests that plant hybrids ‘‘bridge’’ the genetic gap between actual and potential host species, and that, for this reason, herbivorous insects are more likely to evolve an expanded host range in the presence of hybrids. While intuitively appealing, the hypothesis has two implicit assumptions: that phenotypic gaps between potential hosts limit host range, and that characters controlling host use are additively inherited in plant hybrids. Evaluation of these assumptions suggests that operation of the hybrid bridge hypothesis is relatively uncommon. In addition, the hypothesis has not been well integrated into existing theoretical and empirical work on …

Two New Nymphalidae From Western North Carolina: New Subspecies Of Speyeria Aphrodite And Phyciodes Batesii, Ronald R. Gatrelle

Two new subspecies are described from Macon County, North Carolina, United States. Speyeria aphrodite cullasaja is characterized by dorsal melanism, especially in females, by usually lacking the dorsal FW basal spots in cell Cu1 and Cu2, and by a narrowed buff marginal band on the ventral HW (sometimes absent in females). Phyciodes batesii maconensis males are characterized by wholly yellow ventral hind wings devoid of any dark marginal dusting or whitish crescents; and females occasionally possessing, lightly dusted, brown margins and rarely having a silvered marginal ventral HW spot. PPhyciodes batesii maconensis larvae are gregarious Aster feeders. Females are …

The Rediscovery, Taxonomy, And Biology Of Chlosyne Gorgone Gorgone And Chlosyne Ismeria (Nymphalidae) In Burke County, Georgia, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

On April 24, 1993 a colony of Chlosyne gorgone gorgone was found in Orangeburg County, South Carolina, United States. This led to the rediscovery on April 27, 1993 of C. g. gorgone at its type locality in Burke County, Georgia. This species had not been seen or collected anywhere in east coastal Georgia or coastal South Carolina since its description in 1810. The type locality is xeric, scrub oak sandhill. This habitat is generally unsuitable for the survival of later broods. The larvae of nominate gorgone have only been found on Helianthus divaricatus. Topotypical gorgone differ slightly, …

An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle

Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette

Green Canyon Environmental Research Area, Logan Utah

Despite their temperate to subarctic geographic range, American martens (Martes americana) possess a thermally inefficient morphology. The lack of morphological adaptations for reducing thermal costs suggests that marten may use behavioral strategies to optimize thermal budgets. During the winters of 1989-1990 and 1990-1991, we radio-collared and monitored the diel activity of 7 martens. A log-linear model suggested that the presence or absence of light was the only factor associated with marten activity patterns (p < 0.001). A regression of the percentage of active fixes on ambient temperature failed to detect an association (b = -4.45, p = 0.084, n = 12). Contents of marten seats suggested that their activity was consistent with the prey-vulnerability hypothesis. While martens must balance multiple life requisites, their activity patterns suggest that they accept increased thermal costs in order to increase foraging efficiency. However, the nocturnal activity of martens during winter was also consistent with the hypothesis that they may be able to limit their own exposure to predation risk. The nocturnal habits of Newfoundland martens in the winter were consistent with the hypothesis of avoidance of predation risk.

Factors Affecting Nitrogen Fixation Rates In Termites (Isoptera: Rhinotermitidae: Reticulitermes) And Termite Nitrogen Contributions Of Forest Ecosystems, Anthony Duane Curtis

Biological Sciences Theses & Dissertations

Termites host symbiotic bacteria that fix atmospheric nitrogen, which makes termites important in the biogeochemical cycling of nitrogen in ecosystems. The objective of this study was to estimate annual nitrogen contributions by termites by examining seasonal rates of nitrogen fixation, seasonal abundance of different termite castes and their nitrogenase activity, the effects of dietary nitrogen on nitrogenase activity, and low oxygen and high carbon dioxide atmospheres on termite nitrogenase activity, and the accuracy of mark-recapture studies to estimate termite population size.

Termite nitrogen fixation rates were monitored monthly for 10 Reticulitermes Holmgren colonies from June, 1993, to December, 1995. Rates …
