They most often attract attention when they are seen hovering at flowers in late spring and early summer. It can be difficult to distinguish the three “bumble bee clearwing” moths that occur in Colorado, particularly when they are actively moving about plants. The three species are approximately the same size, with wingspans that range between 3.2 to 5.5cm. The hummingbird clearwing is the largest and distinguished by having yellow legs, an Figure 2. Amphion floridensis, the Nessus olive/olive yellow thorax and dark abdomen with sphinx. small patches. The edges of the wings have a thick bordering edge of reddish brown. The snowberry clearwing has black legs, a black band that runs through the eye and along the thorax, a golden/olive golden thorax and a brown or black abdomen with 1-2 yellow bands. The head and thorax of the Rocky Mountain clearwing is brownish olive or olive green and the abdomen black or olive green above, with yellow underside. Although the caterpillar stage of all the clearwing sphinx moths feed on foliage of various shrubs and trees, damage is minimal, none are considered pest species.

  • Insect Survey of Four Longleaf Pine Preserves
    A SURVEY OF THE MOTHS, BUTTERFLIES, AND GRASSHOPPERS OF FOUR NATURE CONSERVANCY PRESERVES IN SOUTHEASTERN NORTH CAROLINA Stephen P. Hall and Dale F. Schweitzer November 15, 1993 ABSTRACT Moths, butterflies, and grasshoppers were surveyed within four longleaf pine preserves owned by the North Carolina Nature Conservancy during the growing season of 1991 and 1992. Over 7,000 specimens (either collected or seen in the field) were identified, representing 512 different species and 28 families. Forty-one of these we consider to be distinctive of the two fire- maintained communities principally under investigation, the longleaf pine savannas and flatwoods. An additional 14 species we consider distinctive of the pocosins that occur in close association with the savannas and flatwoods. Twenty nine species appear to be rare enough to be included on the list of elements monitored by the North Carolina Natural Heritage Program (eight others in this category have been reported from one of these sites, the Green Swamp, but were not observed in this study). Two of the moths collected, Spartiniphaga carterae and Agrotis buchholzi, are currently candidates for federal listing as Threatened or Endangered species. Another species, Hemipachnobia s. subporphyrea, appears to be endemic to North Carolina and should also be considered for federal candidate status. With few exceptions, even the species that seem to be most closely associated with savannas and flatwoods show few direct defenses against fire, the primary force responsible for maintaining these communities. Instead, the majority of these insects probably survive within this region due to their ability to rapidly re-colonize recently burned areas from small, well-dispersed refugia.

  • Fish Relationships with Large Wood in Small Streams
    Amencan F~sheriesSociety Symposium 37:179-193, 2003 Fish Relationships with Large Wood in Small Streams USDA Forest Service, Southern Research Station, Department ofFisheries and Wildlife Virginia Tech, Blacksburg, Virginia 24060, USA USDA Forest Service, Southern Research Station 1000 Front Street, Oxford, Massachusetts 38655, USA Abstracf.-Many ecological processes are associated with large wood in streams, such as forming habitat critical for fish and a host of other organisms. Wood loading in streams varies with age and species of riparian vegetation, stream size, time since last disturbance, and history of land use. Changes in the landscape resulting from homesteading, agriculture, and logging have altered forest environments, which, in turn, changed the physical and biological characteristics of many streams worldwide. Wood is also important in creating refugia for fish and other aquatic species. Removing wood from streams typically results in loss of pool habitat and overall complexity as well as fewer and smaller individuals of both coldwater and warmwater fish species. The life histories of more than 85 species of fish have some association with large wood for cover, spawning (egg attachment, nest materials), and feeding. Many other aquatic organisms, such as crayfish, certain species of freshwater mus- sels, and turtles, also depend on large wood during at least part of their life cycles. Introduction Because decay rate and probability of displace- ment are a function of size, large pieces have a Large wood can profoundly influence the struc- greater influence on habitat and physical processes ture and function of aquatic habitats from head- than small pieces.

Prof. Moraes Rego, s/n, Cidade Universitária, 50670-901, Recife, Pernambuco, Brasil. E-mail:[email protected] ABSTRACT: The caatinga, a thorn-shrub succulent savannah, is located in Northeastern Brazil and characterized by a short and irregular rainy season and a severe dry season. Insects are only abundant during the rainy months, displaying a strong seasonal pat- tern. Here we present data from a yearlong Sphingidae survey undertaken in the reserve Estação Ecológica do Seridó, located in the state of Rio Grande do Norte. Hawkmoths were collected once a month during two subsequent new moon nights, between 18.00h and 05.00h, attracted with a 160-watt mercury vapor light. A total of 593 specimens belonging to 20 species and 14 genera were col- lected. Neogene dynaeus, Callionima grisescens, and Hyles euphorbiarum were the most abundant species, together comprising up to 82.2% of the total number of specimens collected. These frequent species are residents of the caatinga of Rio Grande do Norte. The rare Sphingidae in this study, Pseudosphinx tetrio, Isognathus australis, and Cocytius antaeus, are migratory species for the caatinga.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • Clarks River NWR Hunt Plan Intra-Service Consultation 61
    REGION 4 INTRA-SERVICE SECTION 7 BIOLOGICAL EVALUATION FORM Originating Person: Kimberly Sykes Telephone Number: 270-527-5770 E-Mail: [email protected] Date: September 20, 2019 PROJECT NAME (Grant Title/Number): Clarks River NWR Hunt Plan - Increase Hunting Season Structure and Alignment The purpose of this proposed action is to provide compatible wildlife-dependent recreational opportunities on Clarks River NWR. The need of the proposed action is to meet the Service’s priorities and mandates as outlined by the National Wildlife Refuge System Administration Act of 1966, as amended by the National Wildlife Refuge System Improvement Act of 1997 (NWRSIA) to “recognize compatible wildlife-dependent recreational uses as the priority general uses of the NWRS” and “ensure that opportunities are provided within the NWRS for compatible wildlife- dependent recreational uses.” 16 U.S.C. 668dd(a)(4)). All Clarks River NWR public activities are designed to contribute to or be compatible with all refuge objectives. Clarks River NWR will continue to provide high quality, wildlife-oriented recreation to the general public and the opportunity to utilize a valuable renewable resource. A well-managed public use program will protect and preserve wildlife resources and habitats as well as maintain refuge resources by minimizing negative impacts and enhancing wildlife populations and habitat diversity. Public hunting on Clarks River NWR is an appropriate and compatible form of wildlife oriented public recreation, which is compatible with the purpose for which the Refuge was established. Hunting, being a viable management tool when used wisely, often prevents the overpopulation of species within a given habitat community and can provide for greater wildlife diversity.

Depto. de Biologia Animal, Universidade Federal de Viçosa (UFV), Avenida Peter Henry Rolfs, s/n, Campus Universitário, 36570- 000 Viçosa, MG, Brazil. ([email protected]) ABSTRACT. We describe the mating behavior of Adelosgryllus rubricephalus Mesa & Zefa, 2004. In trials carried out in laboratory we verified the following mating sequence: (1) sexual recognition by antennation; (2) courtship with male turning his abdomen towards the female, performing mediolateral antennae vibration, jerking its body antero-posteriorly and stridulating intermittently, while receptive female drums on the male’s abdomen tip, cerci and hind-tibia with her palpi or foretarsi; the male then stops and stays motionless for some seconds, extrudes the spermatophore and both restart the behavioral sequence described above; (3) copulation: male underneath female; with his tegmina inclined forward, and joins his genitalia to the female’s to promote sperm transference ; the female steps off the male, occurring a brief end-to-end position; (4) postcopulation: without guarding behavior; male retains the spermatophore and eats it. We quantified elapsed time of each behavioral sequence and discussed its implications in the observed mating behavior. KEYWORDS. Insecta, Phalangopsidae, crickets, courtship, copulation.
