Lesions After Sting
Saddleback Caterpillar Forest Huval, D. Ring, T.E. Reagan, Dale K.Pollet Description The saddleback caterpillar (Acharia stimulea) is a sluglike caterpillar that has a bright brown spot in the middle of a green saddle-shaped area on its back. It has four prominent horns on each end of the body that hold potent hemolytic venom. The caterpillars can grow up to 1 inch (2.54 cm) when mature. Saddlebacks are solitary feeders and can be found on a variety of foliage, including apple, basswood, cherry, chestnut, dogwood, elm, maple, oak, plum and even corn. The saddleback caterpillar is found across the eastern United States, ranging from Florida to New York, and as far westward as Texas, Indiana and Kansas. Sting Reactions Saddlebacks are venomous and are among the most common stinging caterpillars in North America. The saddleback sting is immediately painful, with radiation from the site of the sting to the local lymphatic group. Without blistering, symptoms usually subside within two to eight hours. Symptoms, including migraines, gastrointestinal issues and asthma, can last for five hours. A sting may leave red blotches on the site. Allergies to these stings have been documented, and stings should be watched for any potential anaphylactic reaction. Management of Stings TOP: Saddleback caterpillar, John A.

A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains, -

MORSY2 Military Medical Academy1 and Department of Parasitology, Faculty of Medicine, Ain Shams University, Cairo 115662, Egypt Abstract Spider bites are uncommon medical events, since there are limited number of spiders world- wide with fangs strong enough to pierce human skin, and most spiders bite humans only as a fi- nal defense when being crushed between skin and another object. Thus, most lesions attributed to spider bites are caused by some other etiology. The spiders that can cause medically signifi- cant bites include widow and false widow spiders (worldwide), recluse spiders (mostly North and South America), Australian funnel web spiders (eastern coastal Australia) and Phoneutria spiders (Brazil). Acute spider bites most commonly result in a solitary papule, pustule, or wheal. Systemic symptoms can accompany envenomation of widow; funnel web, and Phoneu- tria spiders, and less often, those of recluse spiders.

Kons Jr. Last Update: June 2001 Abstract A systematic check list of 489 species of Lepidoptera collected in the University of Florida Natural Area Teaching Lab is presented, including 464 species in the superfamilies Drepanoidea, Geometroidea, Mimalonoidea, Bombycoidea, Sphingoidea, and Noctuoidea. Taxa recorded in Psychidae, Yponomeutidae, Sesiidae, Cossidae, Zygaenoidea, and Thyrididae are also included. Moth taxa were collected at ultraviolet lights, bait, introduced Bahiagrass (Paspalum notatum), and by netting specimens. A list of taxa recorded feeding on P. notatum is presented. Introduction The University of Florida Natural Area Teaching Laboratory (NATL) contains 40 acres of natural habitats maintained for scientific research, conservation, and teaching purposes. Habitat types present include hammock, upland pine, disturbed open field, cat tail marsh, and shallow pond. An active management plan has been developed for this area, including prescribed burning to restore the upland pine community and establishment of plots to study succession (http://csssrvr.entnem.ufl.edu/~walker/natl.htm). The site is a popular collecting locality for student and scientific collections. The author has done extensive collecting and field work at NATL, and two previous reports have resulted from this work, including: a biodiversity inventory of the butterflies (Lepidoptera: Hesperioidea & Papilionoidea) of NATL (Kons 1999), and an ecological study of Hermeuptychia hermes (F.) and Megisto cymela (Cram.) in NATL habitats (Kons 1998). Other workers have posted NATL check lists for Ichneumonidae, Sphecidae, Tettigoniidae, and Gryllidae (http://csssrvr.entnem.ufl.edu/~walker/insect.htm). -
What's Eating You? Tarantulas (Theraphosidae)
Close enCounters With the environment What’s Eating You? Tarantulas (Theraphosidae) Lauren E. Krug, BS; Dirk M. Elston, MD arantulas belong to the family Theraphosidae, which contains more than 900 species of T hairy and often very large spiders (Figure). Depending on the species, the tarantula’s body length ranges from 1 to 4 in with 3- to 12-in leg spans. At 12 in, the largest reported species is the Goliath bird- eating spider (Theraphosa blondi). The tarantula’s body consists of 4 pairs of legs that terminate in retractable claws, allowing the spider to grip and climb. Two additional pointed appendages called chelicerae are located just below the eyes and are used to grip food and prey. They contain the venomCUTIS glands that allow the spider to immobilize and kill its prey.1 In addition to the regular hairs that cover the Tarantula. spider’s body, most New World species possess barbed urticating hairs that can be released to defend the spider when it feels threatened.

Swarth, C. Et Al. the 2007 Jug Bay Bioblitz Reliort. 2008
2007 Jug Bay BioBlitz Report Christopher Swarth, Lindsay Hollister, Elaine Friebele, Karyn Molines and Susan Matthews Jug Bay Wetlands Sanctuary December 2008 Introduction A BioBlitz is a 24-hour field survey and inventory of organisms in a well-defined area such as a park or other natural area. The objective of this intensive survey is to generate a catalog or list of all species that are identified or collected during the brief survey period. The first BioBlitz in the United States was conducted in 1996 in Washington, DC. Today dozens of BioBlitzes are held annually in the United States (see Wikipedia Encyclopedia; http://en.wikipedia.org/wiki/BioBlitz. A BioBlitz increases local knowledge of biodiversity and involves local naturalists and the public in coordinated fieldwork and observation. The surveys raise the awareness among the general public about the natural world and the importance of biodiversity. The species distribution and occurrence information that is obtained from a BioBlitz also provides resource managers with a deeper understanding of the natural lands under their management, thus enabling improved habitat stewardship. The 2007 Jug Bay BioBlitz took place at the Jug Bay Wetlands Sanctuary over a 24-hour period, from 12:00 (noon) on 15 September to 12:00 on 16 September. We organized this event in order to take advantage of the growing interest in biodiversity by the public and to tap in to the community of active, highly skilled naturalists in the Washington DC/Baltimore area. For this first-time effort we concentrated the field surveys on groups of organisms for which local biogeographical information was poor or incomplete (for example, ants, ground bees, spiders and zooplankton), rather than on the groups for which our knowledge on distribution was relatively thorough such as birds and herps. -

PATHOLOGY OF THE DERMATITIS CAUSED BY MEGALO- PYGE OPERCULARIS, A TEXAN CATERPILLAR.* BY NATHAN CHANDLER FOOT, M.D. (From the Department of Comparative Pathology, GeorgeFabyan Foundation, Ha~vard Medical School, Boston.) PLATES 62 AND 63. (Receivedfor publication, December22, 1921.) INTRODUCTION. A small larval moth has been causing dermatitis in southern Texas for the past decade, particularly during the years 1913 and 1920. It is known locally as the puss-caterpillar, opossum bug, Italian asp, and, by Mexicans, el perrito (the puppy), and belongs to the family Megalo- pygida~, of the group known as slug caterpillars. As it has not been investigated systematically from a medical standpoint up to the present time, the work reported in this paper was undertaken at the suggestion of Mr. F. C. Bishopp, of the United States Bureau of Entomology, who is stationed at Dallas, Texas, and to whom the writer is much indebted for the caterpillars studied and notes concerning their distribution and injurious effects. Mr. Bishopp reports the following clinical symptoms from regions infested by the caterpillars. All stages of the larva are capable of inflicting stings, the intensity of the lesions being in proportion to the size of the caterpillar. There is a marked variability in the susceptibility of different individuals. At some seasons there have been epidemics of dermatitis so widespread that public schools in San Antonio, Texas, were closed until the surrounding trees could be sprayed. The severity of the sting varies with its location and the thickness of the skin affected. There is at first a localized, painful area of erythema, which burns intensely. -
