Annotated Records of Species of Pentatomoidea (Hemiptera) Collected at Lights

Records of specimens of Pentatomoidea collected at various light sources in Alabama, Arizona, Florida, Georgia, Illinois, Louisiana, and Texas are presented. Of the 51 species and subspecies reported, about 75% belong to the Pentatomidae

The First Records in Illinois of \u3ci\u3eHeliconius Charitonius\u3c/i\u3e (Lepidoptera: Heliconiidae) and \u3ci\u3ePhoebis Agarithe\u3c/i\u3e (Lepidoptera: Pieridae)

(excerpt) Our key to Illinois butterflies, exclusive of the skippers (Hesperiidae), was published in 1980. It includes those butterflies listed by Irwin and Downey in their 1973 Illinois checklist plus two species,Anaea aidea (Guerin-Meneville) (Nymphalidae) and Celastrina ebenina Clench (Lycaenidae), added to the state list after 1973

A List of the Scutelleroidea of the La Rue-Pine Hills Ecological Area with Notes on Biology

A survey of the scutelleroid fauna of the LaRue-Pine Hills Ecological Area, Union County, Illinois was conducted from May, 1972 to September, 1974. Forty-nine species were collected, five of which were state records. The remaining 44 represented over 57% of the species presently listed for Illinois. Life history information was collected for the majority of species, including host plants, predators and parasites. The pertinent literature is summarized for each species

A List of the Butterflies (Lepidoptera: Papilionoidea) of the La Rue-Pine Hills Ecological Area

A survey of the adult butterfly fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted from March through July in 1979, and March through November in 1980. Forty nine species and subspecies were collected including all six papilionids known to occur in Illinois. Notes were taken on seasonal flight periods and butterfly-plant associations

Diversity and Community Structure of Stream Insects in a Minimally Disturbed Forested Watershed in Southern Illinois

The Lusk Creek Watershed, located in Pope County, IL, long has been rec- ognized as a high quality area of biological significance, but surveys of the stream macroinvertebrate fauna have been limited. Thus, a survey of the benthic insect community at 11 sites in the upper portion of Lusk Creek was conducted from May 2003 to April 2005. A total of 20,888 specimens, mostly immatures, were examined during the study and represented eight orders. The Diptera, by far, was the most abundant order, with 18,590 specimens, almost all of which were members of the Chironomidae or Simuliidae. Members of the EPT (Ephemer- optera, Plecoptera, Trichoptera) contributed 1,550 specimens. The Coleoptera was represented by 647 specimens, most of which were members of Stenelmis (Elmidae) (n = 612). The Shannon diversity index (H ́) ranged from 1.07-2.01 for individual sites and was indicative of relatively undisturbed streams in this region. Jackknife analyses of richness estimated that as many as 37 taxa were unobserved in this survey. Results provide information on reference conditions in the region and a foundation for future monitoring

Eastern Range Extension of \u3ci\u3eLeptoglossus Occidentalis\u3c/i\u3e With a Key to Leptoglossus Species of America North of Mexico (Heteroptera: Coreidae)

Leptoglossus occidentalis is reported for the first time from Illinois and Michigan, and confirmed for Indiana. A key to the species of Leptoglossus occurring in America north of Mexico is presented

Potential structural material problems in a hydrogen energy system

Potential structural material problems that may be encountered in the three components of a hydrogen energy system - production, transmission/storage, and utilization - were identified. Hydrogen embrittlement, corrosion, oxidation, and erosion may occur during the production of hydrogen. Hydrogen embrittlement is of major concern during both transmission and utilization of hydrogen. Specific materials research and development programs necessary to support a hydrogen energy system are described

Assessing invasive plant species as threats in Mojave Desert parks

The invasion and persistence of exotic plant species threatens the natural features that national parks are designed to protect. For example, park managers have witnessed an increase in the frequency, extent and intensity of fires along with a reduction in native species richness and diversity. Many park managers are familiar with a suite of highly invasive plants, but lack a comprehensive and systematic way of prioritizing invasive plant species based on potential threats to the parks’ resources. We have entered into a collaborative project with the National Park Service’s Inventory and Monitoring program to develop an invasive plant early detection and monitoring protocol for the Mojave Desert Network (MOJN),which includes seven national park units. Our first step was to identify and prioritize invasive plants presently occurring or having the potential to invade each of the seven parks. To date, we have compiled a list of 350 species considered unnatural or weedy to the Mojave Desert region. From this comprehensive list, 154 were identified as having a medium or higher impact on the desert ecosystem. Since the MOJN hosts a wide variety of habitat types, our second step was to identify locations that are most vulnerable to invasion. We are currently synthesizing existing literature on species richness and elevation relationships, life-history and spatial distribution for these plants species
