Life History of \u3ci\u3eCeratocombus Vagans\u3c/i\u3e (Hemiptera: Heteroptera: Ceratocombidae), With Notes on the Immature Stages

The biology and life stages of Ceratocombus vagans are given together with distributional notes. The current systematic position of Ceratocombidae is reviewed. This species is one of the most generalized Hemiptera: Heteroptera known. Its predatory habits lend credance to the idea that primitive Hemiptera: Heteroptera were predaceous as suggested by Stys and others. Ceratocombus vagans occurs in moss, leaf litter, and under loose bark. It has wide distribution in much of North America

Dead Leaf Clusters as Habitats for Adult \u3ci\u3eCalliodis Temnostethoides\u3c/i\u3e and \u3ci\u3eCardiastethus Luridellus\u3c/i\u3e and Other Anthocorids (Hemiptera: Heteroptera: Anthocoridae)

Two species of Anthocoridae (Hemiptera: Heteroptera) were found in dead-leaf clusters of black oak in west-central Michigan, Calliodis temnostethoides and Cardiastethus luridellus. These clusters resulted from full- leafed trees being blown over by a severe wind storm in May 1998. They contained spiders, springtails, tubiliferan thrips, small beetles, and psocids, besides the predaceous anthocorids. Such habitats are well-known for some bugs elsewhere. Because only adults were collected, it was assumed that the more permanent habitat was likely to be under bark. Further attention to this habitat likely will result in additional records for other species of Anthocoridae

\u3ci\u3eArhyssus Hirtus\u3c/i\u3e (Hemiptera: Heteroptera: Rhopalidae) in Minnesota: The Inland Occurrence of an East Coast Species

Arhyssus hirtus (Hemiptera: Heteroptera: Rhopalidae), is reported from the Cedar Creek Natural History Area, a Long-Term Ecological Research site, outside of Minneapolis, Minnesota where over 4000 species of arthropods have been collected. This species has previously been known only from a narrow zone along the sandy edges of the Atlantic Ocean (Maryland, Massachusetts, New Jersey and New York). The species is known on Hudsonia tomentosa at these ocean sites, but other hosts may be involved at Cedar Creek. This small species of Arhyssus occurs in both micropterous and macropterous forms, unusual for this genus. Thus far, only micropterous forms have been collected at the Minnesota site

Myrmecophyes oregonensis, a new species of Halticini (Hemiptera, Miridae) from the western United States. American Museum novitates ; no. 2697

11 p. : ill. ; 26 cm.Includes bibliographical references (p. 10-11)."Myrmecophyes oregonensis (Hemiptera, Miridae, Orthotylinae, Halticini) is described as new from central and south central Oregon. This is the first record of the genus from the Western Hemisphere. Information is provided on the male and female genitalia, femoral trichobothria, and pretarsus. This saltatorial antlike species apparently breeds on the native perennial bunch grass Agropyron spicatum"--P. [1]

Physiological effects of tourism and associated food provisioning in an endangered iguana

© The Author 2013. Deliberately feeding wildlife is an increasingly popular tourism-related activity despite a limited understanding of long-term impacts on the species being fed. As a result, tourist behaviours that may have adverse impacts on imperiled species have often been encouraged without the necessary evaluation or oversight. Here, we report the responses of Northern Bahamian Rock Iguanas (Cyclura cychlura) to human-visitation pressure and associated food provisioning. We compared a variety of blood chemistry parameters of iguanas subjected to supplemental feeding at popular tourist destinations with iguanas occurring on islands where supplemental feeding does not take place. We demonstrate that male and female iguanas inhabiting tourist-visited islands where supplemental feeding occurs do not differ in body condition or baseline stress and stress response (determined by corticosterone levels) compared with iguanas from non-visited islands. Both males and females from tourist-visited sites experienced a greater incidence of endoparasitic infection and atypical loose faeces. Indicators of dietary nutrition, including glucose, potassium, and uric acid values, also differed for both sexes from tourist-visited and unvisited islands. Male iguanas from visited islands differed significantly from those on non-visited islands in calcium, cholesterol, cobalt, copper, magnesium, packed cell volume, selenium, and triglyceride concentrations, whereas female iguanas from visited islands differed significantly in ionized calcium. Although the interpretation of these differences is challenging, chronic biochemical stressors could compromise individual health over time or decrease survivorship during periods of environmental stress. We suggest protocols that can be adopted throughout the region to ensure that supplemental feeding has fewer impacts on these long-lived iguanas
