Young Department of Entomology 445 Russell Labs University of Wisconsin-Madison Madison, WI 53706 Abstract. A survey of Wisconsin Scarabaeoidea (Coleoptera) conducted from literature searches, collection inventories, and three years of field work (1997-1999), yielded 177 species representing nine families, two of which, Ochodaeidae and Ceratocanthidae, represent new state family records. Fifty-six species (32% of the Wisconsin fauna) represent new state species records, having not previously been recorded from the state. Literature and collection distributional records suggest the potential for at least 33 additional species to occur in Wisconsin. Introduction however, most of Wisconsin's scarabaeoid species diversity, life histories, and distributions were vir- The superfamily Scarabaeoidea is a large, di- tually unknown.

  • A Phylogenetic Analysis of the Dung Beetle Genus Phanaeus (Coleoptera: Scarabaeidae) Based on Morphological Data
    A phylogenetic analysis of the dung beetle genus Phanaeus (Coleoptera: Scarabaeidae) based on morphological data DANA L. PRICE Insect Syst.Evol. Price, D. L.: A phylogenetic analysis of the dung beetle genus Phanaeus (Coleoptera: Scarabaeidae) based on morphological data. Insect Syst. Evol. 38: 1-18. Copenhagen, April, 2007. ISSN 1399-560X. The genus Phanaeus (Scarabaeidae: Scarabaeinae) forms an important part of the dung bee- tle fauna in much of the Western Hemisphere. Here a phylogeny for Phanaeus, including 49 Phanaeus sp., and 12 outgroup taxa, is proposed. Parsimony analysis of 67 morphological characters, and one biogeographical character produced 629 equally parsimonious trees of 276 steps. Oxysternon, the putative sister taxon is nested well within the subgenus Notiophanaeus, implying that Oxysternon might ultimately need to be synonymized with Phanaeus. Species groups of Edmonds (1994) recovered as monophyletic are paleano, endymion, chalcomelas, tridens, triangularis, and quadridens. An ‘unscaled’ equal weighting analysis yielded 57,149 equally parsimonious trees of 372 steps. The strict consensus of these trees yielded a mono- phyletic Phanaeus with the inclusion of Oxysternon. Bootstrap values are relatively low and some clades are unresolved. Dana L.

  • Birds As a Factor in the Control of a Stomach Worm of Swine
    38O BirdControl ofStomach Worm of Swine. rAuk[July BIRDS AS A FACTOR IN THE CONTROL OF A STOMACH WORM OF SWINE. • BY r•Lo•sr• B. caxM. Introduction. A GROUPof roundwormparasites known as spirurlds,the name being derived from the superfamilyname Spiruroidea,occur as adultsin a wide variety of hosts,including mammals, reptiles and birds. Theseparasites have an indirectlife history,that is one in which there is involved an intermediate host. This intermediate host is usually a small arthropod, such as an entomostracanor insect; encystedin the body tissuesof the arthropod, the larval form of the parasitedevelops to a stagewhich is infectivefor the final host. Birdswhich feed on arthropodsin largenumbers, such as water birds which eat entomostracans and insectivorous birds which eat insects, are therefore liable to infection with such parasitesand it is not surprisingthat a great variety of adult roundwormsof this groupis found to occurin suchbirds. However, the arthropodswhich are eaten by birds may be in- festedwith roundwormlarvae which as adults parasitizea group of animals other than birds, such as mammals. The fate of such larval parasiteswhich are thus introducedinto the wronghost has beenstudied by earlier workers,notably the French parasitologist Seurat, who found that the larvae migrate into the tissuesof such a host and again encyst. The presentinvestigation resulted from the discoverymade by H. L. Stoddard several years ago that the LoggerheadShrikes (Lanius ludovicianusludovicianus) in northern Florida, chiefly in Leon County, and in southernGeorgia, chiefly in Grady County, were infestedwith large numbersof roundwormsencysted in the walls of the digestivetract.

To assess their distribution in North America, I created a checklist of over 300 beetle species known to colonize dung (Chapter 2). To assess the affect of habitat and location on dung beetle diversity, I conducted sampling at Purple Springs Grazing Reserve and Cypress Hills Interprovincial Park (Chapter 3). Each habitat and location was dominated by different species for both sampling years. The affect of bait treatment and age on the attractiveness of the coprophagous insect community was assessed using fresh and frozen dung baits, with frozen baits being more attractive for the first three days (Chapter 4).

EXPLORING THE MINUTE WORLD OF THE CALIFORNIA ASPHALT DEPOSITS By W. DWIGHT PIERCE The larger mammals and birds, whose bones have been found in the Rancho La Brea asphalt deposits at Hancock Park, Los Angeles, are well known, and have become a vital part of the early story of this region. But, strange to say, with the exception of the passerine birds reported by A. H. Miller in 1929 and 1932, and the rodents and rabbits reported by Lee R. Dice in 1925, no one has critically studied the small life of the pits. Some plants, a few insects, a toad, and other small animals have been reported incidentally. The same may be said of the asphalt deposits of McKittrick and Carpinteria. Many people have thought that the story of the deposits was a closed book, but, in reality, it was less than half the story, and a new chapter is opening as the micro- fauna and microflora are studied. In the early days of the Rancho La Brea explorations a few large beetles were found in the marginal diggings and were listed. All, however, were species still existent. A few years ago, Miss Jane Everest began a more detailed analysis of the asphaltum and isolated many insect remains from pits A, B, and Bliss 29, and other scattered excavations. These will be reported upon in the present serie$, group by group.
