    SYSTEMATICS OF THE MEGADIVERSE SUPERFAMILY GELECHIOIDEA (INSECTA: LEPIDOPTEA) DISSERTATION Presented in Partial Fulfillment of the Requirements for The Degree of Doctor of Philosophy in the Graduate School of The Ohio State University By Sibyl Rae Bucheli, M.S. ***** The Ohio State University 2005 Dissertation Committee: Approved by Dr. John W. Wenzel, Advisor Dr. Daniel Herms Dr. Hans Klompen _________________________________ Dr. Steven C. Passoa Advisor Graduate Program in Entomology ABSTRACT The phylogenetics, systematics, taxonomy, and biology of Gelechioidea (Insecta: Lepidoptera) are investigated. This superfamily is probably the second largest in all of Lepidoptera, and it remains one of the least well known. Taxonomy of Gelechioidea has been unstable historically, and definitions vary at the family and subfamily levels. In Chapters Two and Three, I review the taxonomy of Gelechioidea and characters that have been important, with attention to what characters or terms were used by different authors. I revise the coding of characters that are already in the literature, and provide new data as well. Chapter Four provides the first phylogenetic analysis of Gelechioidea to include molecular data. I combine novel DNA sequence data from Cytochrome oxidase I and II with morphological matrices for exemplar species. The results challenge current concepts of Gelechioidea, suggesting that traditional morphological characters that have united taxa may not be homologous structures and are in need of further investigation. Resolution of this problem will require more detailed analysis and more thorough characterization of certain lineages. To begin this task, I conduct in Chapter Five an in- depth study of morphological evolution, host-plant selection, and geographical distribution of a medium-sized genus Depressaria Haworth (Depressariinae), larvae of ii which generally feed on plants in the families Asteraceae and Apiaceae.

  • English Nature Research Report No
    23 6 REQUIREMENTS FOR CONSERVATION 6.1 Introduction A very few examples of the artificial habitats considered in this report have statutory protection as SSSI or LNRs, A few, not all the same ones, have good invertebrate records. None have good enough invertebrate records, as seen in the Introduction, to be able to define invertebrate "communities" by more than species lists and, cxcasionally, relative abundances of some species in a very few years. The importance of such habitats for biodiversity consewation is however substantial, as demonstrated above. Few Broad Habitat types could boast as inany as 12-15% of the list of nationally scarce and rare species, and no other for which no Key Habitat has been defined. The situation is therefore one in which we have the minimal knowledge needed to know how important the problem is and, so far, only the skeleton of a conservation strategy which will address it, Clearly we need to know more about the invertebrates, more about the sites concerned and have a better strategy for conservation. It is not easy to judge how to do this and to set the priorities in the right urder. In the following I leave aside the purely synanthropic species which are either controversial for conservation (such as specific parasites) or common species present as curiosities well outside their global range (such as camel crickets and the range of tropical pyralid moths which breed in aquatic nurseries). 6.2 lnvertcbratc surveys We know too little about the invertebrate faunas of artificial sites, in particular and in general, There are two consequences of this, First, important sites may disappear unknown because they have not been surveyed or have been inadequately surveyed.

  • 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.

  • South-Central England Regional Action Plan
    Butterfly Conservation South-Central England Regional Action Plan This action plan was produced in response to the Action for Butterflies project funded by WWF, EN, SNH and CCW by Dr Andy Barker, Mike Fuller & Bill Shreeves August 2000 Registered Office of Butterfly Conservation: Manor Yard, East Lulworth, Wareham, Dorset, BH20 5QP. Registered in England No. 2206468 Registered Charity No. 254937. Executive Summary This document sets out the 'Action Plan' for butterflies, moths and their habitats in South- Central England (Dorset, Hampshire, Isle of Wight & Wiltshire), for the period 2000- 2010. It has been produced by the three Branches of Butterfly Conservation within the region, in consultation with various other governmental and non-governmental organisations. Some of the aims and objectives will undoubtedly be achieved during this period, but some of the more fundamental challenges may well take much longer, and will probably continue for several decades. The main conservation priorities identified for the region are as follows: a) Species Protection ! To arrest the decline of all butterfly and moth species in South-Central region, with special emphasis on the 15 high priority and 6 medium priority butterfly species and the 37 high priority and 96 medium priority macro-moths. ! To seek opportunities to extend breeding areas, and connectivity of breeding areas, of high and medium priority butterflies and moths. b) Surveys, Monitoring & Research ! To undertake ecological research on those species for which existing knowledge is inadequate. Aim to publish findings of research. ! To continue the high level of butterfly transect monitoring, and to develop a programme of survey work and monitoring for the high and medium priority moths.

  • Proceedings of the United States National Museum
    PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM issued |i;|\X^H by the SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol.86 Washington: 1939 No. 3064 RESTRICTION OF THE GENUS GELECHIA (LEPIDOP- TERA: GELECHIIDAE), WITH DESCRIPTIONS OF NEW GENERA By August Busck The genus Gelechm Hiibiier/ type G. rhomhella (Schiffermiiller), has become, in the course of years since its erection, a "wastebasket" ^ for hundreds of heterogeneous species of gelechiids that could not readily be assigned to other genera on wing or palpal characters. The result is an aggregation of more than 400 such species under the generic name Gelechia. Quite aside from the inconvenience of such an unwieldy number of species in one genus, it is apparent that this lumping does not represent a natural grouping, but that many of the included species are less related to their associates in the check lists under that genus than they are to the species placed in other genera. Gnorimoschema Busck {Phthorimaea Meyrick), for example, which has been correctly separated for many years on obvious pterogostic and oral characters, is clearly more closely related to Gelechia proper than most of the genera here eliminated from the concept. For this reason it is included in the synoptic tables in this paper, and figures of the genitalia are given for comparison (pi. 68, fig. 2; pi. 65, fig. 36). Several sound attempts have been made by workers in continental Europe, notably Heinemann,^ to make a more natural classification by the erection of separate genera for species with certain slight modi- fications of wing structure and palpal characters in common, but the 1 Verzeichniss bekannter Schmetterlinge, p.
