Young Department of Entomology University of Wisconsin-Madison 445 Russell Labs 1630 Linden Dr. Madison, WI 53706, U.S.A. Abstract: A three-year survey of Wisconsin Mordellidae (Coleoptera) encompassing a compilation of data from literature records and local collections as well as field work including trapping, hand-collecting, and rearing yielded 68 species comprising 14 genera in three tribes. Sixty-three species (92% of Wisconsin fauna) represent new state species records, not previously recorded from the state in the literature. Plant-associations and state- specific temporal and spatial distribution data for larvae and adults are noted as available. Distributional records suggest 16 additional species and one additional genus are likely to occur in Wisconsin.

  • Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015)
    Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015) By Richard Henderson Research Ecologist, WI DNR Bureau of Science Services Summary This is a preliminary list of insects that are either well known, or likely, to be closely associated with Wisconsin’s original native prairie. These species are mostly dependent upon remnants of original prairie, or plantings/restorations of prairie where their hosts have been re-established (see discussion below), and thus are rarely found outside of these settings. The list also includes some species tied to native ecosystems that grade into prairie, such as savannas, sand barrens, fens, sedge meadow, and shallow marsh. The list is annotated with known host(s) of each insect, and the likelihood of its presence in the state (see key at end of list for specifics). This working list is a byproduct of a prairie invertebrate study I coordinated from1995-2005 that covered 6 Midwestern states and included 14 cooperators. The project surveyed insects on prairie remnants and investigated the effects of fire on those insects. It was funded in part by a series of grants from the US Fish and Wildlife Service. So far, the list has 475 species. However, this is a partial list at best, representing approximately only ¼ of the prairie-specialist insects likely present in the region (see discussion below). Significant input to this list is needed, as there are major taxa groups missing or greatly under represented. Such absence is not necessarily due to few or no prairie-specialists in those groups, but due more to lack of knowledge about life histories (at least published knowledge), unsettled taxonomy, and lack of taxonomic specialists currently working in those groups.

  • The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
    INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

  • Effects of Prescribed Fire and Social Insects on Saproxylic Beetles in A
    www.nature.com/scientificreports OPEN Efects of prescribed fre and social insects on saproxylic beetles in a subtropical forest Michael D. Ulyshen1 ✉ , Andrea Lucky2 & Timothy T. Work3 We tested the immediate and delayed efects of a low-intensity prescribed fre on beetles, ants and termites inhabiting log sections cut from moderately decomposed pine trees in the southeastern United States. We also explored co-occurrence patterns among these insects. Half the logs were placed at a site scheduled for a prescribed fre while the rest were assigned to a neighboring site not scheduled to be burned. We then collected insects emerging from sets of logs collected immediately after the fre as well as after 2, 6, 26 and 52 weeks. The fre had little efect on the number of beetles and ants collected although beetle richness was signifcantly higher in burned logs two weeks after the fre. Both beetle and ant communities difered between treatments, however, with some species preferring either burned or unburned logs. We found no evidence that subterranean termites (Reticulitermes) were infuenced by the fre. Based on co-occurrence analysis, positive associations among insect species were over two times more common than negative associations. This diference was signifcant overall as well for ant × beetle and beetle × beetle associations. Relatively few signifcant positive or negative associations were detected between termites and the other insect taxa, however. Dead wood is one of the most important resources for biodiversity in forests worldwide, supporting diverse and interacting assemblages of invertebrates, fungi and prokaryotes1,2. In addition to many species that oppor- tunistically beneft from dead wood, about one third of all forest insect species are saproxylic, meaning they are strictly dependent on this resource at some stage in their life cycle, and many of them have become threatened in intensively managed landscapes3,4.
