FLINT, JR. I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 520 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the worid. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. Robert McC. Adams Secretary Smithsonian Institution SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 520 Studies of Neotropical Caddisflies, XLV: The Taxonomy, Phenology, and Faunistics of the Trichoptera of Antioquia, Colombia Oliver S. Flint, Jr. SMITHSONIAN INSTITUTION PRESS Washington, D.C. 1991 ABSTRACT Oliver S. Flint, Jr. Studies of Neotropical Caddisflies, XLV: The Taxonomy, Phenology, and Faunistics of the Trichoptera of Antioquia, Colombia. Smithsonian Contributions to Zoology, number 520, 113 pages, 412 figures, 6 graphs, 1 map, 11 tables, 1991.—The Department of Antioquia, with its capital Medellin, is situated in the northwestern quadrant of Colombia, South America. In elevation it runs from sea level to 3,900 meters and, in general, has abundant rainfall. Most of the material comes from the montane areas near Medellin, including year long emergence trap collections made at 3 sites by U. Matthias. These emergence trap collections show a definite correlation between emergence and rainfall pattern. The fauna, although nearly 46% is still known only from this one region, seems to show a distribution pattern that extends along the Andes to Ecuador and/or Venezuela, at a minimum. The 37 genera recorded belong to 13 families, and contain 124 named species, plus another 23 species whose material was not adequate for description. Of the 124 named species, 69 are described as new in this work. All the species are keyed, discussed, and illustrated. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.

Apresentação O presente trabalho traz informações a respeito dos animais invertebrados, com destaque para aqueles que habitam o ambiente cavernícola. Sem qualquer pretensão de esgotar um assunto tão vasto, um dos objetivos principais deste guia básico de identificação é apresentar e caracterizar esse grande grupo taxonômico de maneira didática e objetiva. Este guia de identificação foi elaborado para auxiliar os técnicos e profissionais de várias áreas de conhecimento nos trabalhos de campo e nas vistorias técnicas realizadas pelo Ibama. É preciso esclarecer que este guia não pretende formar “especialista”, mesmo porque para tanto seriam necessários muitos anos de dedicação e aprendizado contínuo. Longe desse intuito, pretende- se apenas que este trabalho sirva para despertar o interesse quanto à conservação dos invertebrados de cavernas (meio hipógeo) e também daqueles que vivem no ambiente externo (meio epígeo).

  • Trichoptera: Calamoceratidae) in a Tropical Rainforest Stream of Puerto Rico
    Life history and phenology of Phylloicus pulchrus (Trichoptera: Calamoceratidae) in a tropical rainforest stream of Puerto Rico Limarie J. Reyes-Torres1, 2 & Alonso Ramírez2 1. Department of Biological Sciences, University of Southern Mississippi, Hattiesburg, MS, 39460; [email protected] 2. Department of Environmental Sciences, University of Puerto Rico, San Juan, Puerto Rico 00931; [email protected] Received 30-X-2017. Corrected 12-II-2018. Accepted 08-III-2018. Abstract: Caddisflies are abundant, diverse, and important insects in freshwater ecosystems. However our knowledge on their life history is incomplete, in particular for the Neotropics. The objectives of this study were to describe the life history and phenology of Phylloicus pulchrus in the Luquillo Experimental Forest, Puerto Rico. Eggs and larvae were reared to determine the species lifespan and time in each instar. Larval instars were determined based on a head width vs. pronotal suture length correlation (N= 120). Larvae and benthic leaf litter were sampled monthly at a headwater stream for a year; all specimens were classified into instars based on their case size. Adult P. pulchrus were sampled monthly for a year with a light trap and at various times with a Malaise trap. Monthly environmental variables were related to species and sex abundance. There was a gradient of egg development where eggs (within compound masses) closest to the water were more developed. There were five larval instars and reared larvae showed longer development times and more variable body measurements in later instars. The best correlation for larval instar determination was case length-head width (Pearson= 0.90, P= 2.2e-16, N= 120).

  • Insects and Other Arthropods from Kwajalein Atoll (Marshall Islands)
    Vol. XXI, No. 2, December, 1972 271 Insects and other Arthropods from Kwajalein Atoll (Marshall Islands) Bernard B. Sugerman U. S. ARMY, HAWAII Kwajalein Atoll is located in the Ralik (Sunset or Western) Chain of the Marshall Islands in the West Central Pacific Ocean. It is 2100 nautical miles southwest of San Francisco. Lying less than 700 miles north of the Equator, Kwajalein is in the latitude of Panama and the southern Philippines; it is in the longitude of New Zealand, 2300 miles south, and the Kamchatka Peninsula, USSR, 2600 miles north. Kwajalein Atoll is of coral reef formation in the shape of a crescent loop enclosing a lagoon. Situated on the reef are approximately 100 small islands, with a total land area of only 5.6 square miles (3584 acres). The three largest islets, Kwajalein (1.2 square miles), Roi-Namur and Ebadon, at the extremities of the Atoll, account for nearly half the total land area. While the typical size of the remaining isles may be about 140 by 225 m, the smallest islands are no more than sand cays that merely break the water's surface at high tide. The lagoon enclosed by the reef is the world's largest lagoon, having a surface area of 902 square miles. The Atoll's longest dimension is 75 miles from Kwajalein to Ebadon, and its average width is about 15 miles. Kwajalein Islet at the Atoll's southern tip and Roi-Namur at its northern extremity are 50 miles apart. All islets are flat and few natural points exceed 15 feet above mean sea level; those which do are sand dunes.

  • Spatial and Temporal Occurrence of Beet Armyworm (Lepidoptera: Noctuidae) Moths in Mississippi
    Armyworm Symposium 2002: Adamczyk et al. 229 SPATIAL AND TEMPORAL OCCURRENCE OF BEET ARMYWORM (LEPIDOPTERA: NOCTUIDAE) MOTHS IN MISSISSIPPI J. J. ADAMCZYK, JR.1, M. R. WILLIAMS2, J. T. REED2, D. W. HUBBARD1 AND D. D. HARDEE1 1USDA, ARS, Southern Insect Management Research Unit P.O. Box 346, Stoneville, MS 38776 2Mississippi State University, Department of Entomology and Plant Pathology Clay Lyle Building, Mississippi State, MS 39762 ABSTRACT Throughout 1994-2000, adult beet armyworm, Spodoptera exigua (Hübner) populations were monitored in the delta and hill regions of Mississippi using pheromone traps. Signifi- cant differences in the mean number of moths trapped were found among different geo- graphical areas of the state. A trend was observed where the greatest number of moths was found in the Mississippi Delta, located in the western region of the state. The lowest number of moths was found in the hills located in the eastern region of the state. An annual profile of beet armyworm populations in the western section of the Mississippi Delta also revealed that wide-scale immigration of this pest typically begins at 200 Julian days (mid-July). This date could be used as a benchmark to determine when and if population levels are high enough to have the potential to cause economic damage to crops in the Mississippi Delta. Key Words: Spodoptera, migration, movement RESUMEN A travéz de los años 1994 a 2000, se realizaron un monitoreo de las poblaciones de adultos del gusano trozador de la remolacha, Spodoptera exigua (Hübner) en las regiones de la Delta y las colinas del Estado de Mississippi usando trampas de feronomas.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • Rapid Assessment of a Coastal Countryside in El Salvador
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol.2(1):34-51, 2009 Research Article Butterfly (Papilionoidea and Hesperioidea) rapid assessment of a coastal countryside in El Salvador Timothy C. Bonebrake1 and Rubén Sorto2 1Stanford University, Center for Conservation Biology, Dept. of Biology, Stanford, CA 94305- 5020. Email: [email protected] 2SalvaNATURA, Conservation Science Program, 33 Ave. Sur. #640. Colonia Flor Blanca, San Salvador, El Salvador, C.A. Email: [email protected] Abstract Conservation organizations often must rely on data collected quickly and cheaply to make informed decisions in unstudied regions. Butterflies represent an opportunity in this respect, in that many species can typically be sampled and identified in a short time and provide an indication of habitat or conservation value as well. During nine days of sampling in June 2008, we found and identified 84 butterfly species and 1,856 butterfly individuals at Playa El Icacal, Department of La Unión, El Salvador, using transect counts. Through species richness estimators and a ratio extrapolation based on a list of species expected to be found onsite, we sampled 40-60% of the butterfly community present. Species richness at the site is estimated to be between 100 and 200 species. Sites with small patches of dry forest (La Bocana and La Laguna) had higher species richness than sites without dry forest (Hacienda Casco, El Manglar, and El Esteron). While two weeks is not enough time to fully document the butterfly community in 20 km2 of neotropical coastal countryside, we were able to provide a valuable estimate of species richness and provide some information as to which areas in the region hold the most conservation value.

  • A Preliminary Assessment of Insect Diversity in Imbak Canyon – Batu Timbang
    Journal of Tropical Biology and Conservation 16: 9–24, 2019 ISSN 1823-3902 E-ISSN 2550-1909 Research Article A Preliminary Assessment of Insect Diversity in Imbak Canyon – Batu Timbang Arthur Y. C. Chung*, Momin Binti, John L. Yukang Forest Research Centre, Sabah Forestry Department, P. O. Box 1407, 90715 Sandakan, Sabah *Corresponding author: [email protected] Abstract This insect diversity survey by the Sabah Forestry Department team was carried out from 16th to 20th of August, 2017 in Imbak Canyon – Batu Timbang area. Nocturnal insect diversity was assessed through light-trapping while diurnal insects were documented through fruit-baited traps, sweep nets and forceps. The mean nocturnal insect species richness was 48 species while the mean abundance was 55 individuals. These values were affected by the presence of many wild honeybees, Apis dorsata and the unexpectedly wet weather. Some Bornean endemic species were recorded, which included moths, beetles, dragonflies and a butterfly species. The Bornean endemic butterfly, Papilio acheron, is a rare species documented during the survey. Interesting and iconic species recorded are the Malaysia national butterfly, Trogonoptera brookiana and the world’s largest bush cricket, Macrolyristes imperator. These insect data provide salient information to enhance the conservation of the Batu Timbang forest. They will serve as baseline information for other insect research work in future. Threats, such as forest fire, fragmentation, illegal clearing of vegetation and poaching are likely to indirectly affect the insect fauna. As such, continuous monitoring and enforcement at strategic locations are important to minimize these threats.
