FIELD GUIDE DESCRIPTIONS: Beadle and Leckie (2012) ONLINE PHOTOS: TECHNICAL DESCRIPTION, ADULTS: Clarke (1941); Hodges (1974) TECHNICAL DESCRIPTION, IMMATURE STAGES: ID COMMENTS: The following is based on the description in Clarke (1941). The labial palp is sordid white and the second segment is overlaid with blackish fuscous exteriorly, except at the base and apex. The third segment has a small black spot at the base anteriorly, along with a broad, black sub-apical annulus. The head is gray and the antenna is light fuscous and narrowly annulated with gray. The thorax is gray and suffused with brown anteriorly, and with a faint carmine tint. The forewing is light shining gray and marked with numerous faint, short transverse strigulae. Beginning at the end of the cell there is a conspicuous, sinuous black bar that widens and continues to the extreme base of the costa. Between the costa and the beginning of the bar at the end of the cell, there are two longitudinal brown-edged black dashes (sometimes fused) that are followed on the costa by a small, indistinct light brown shade. The costa is marked with poorly defined, light-brown spots and dashes, and is narrowly edged with pink to slightly beyond the middle. There are a series of small black spots that extend around the termen to the inner margin. The cilia are pale gray with a light-brown suffusion outwardly. The hindwing is pale, shining gray, and darker apically, with paler cilia with narrow light brown bands. The legs are pale ochreous-white and overlaid exteriorly with blackish fuscous, except at the joints and on the hind tibia. The abdomen is sordid ochreous with a slight fuscous suffusion beneath. This species is easily recognized by the sinuous black bar that extends all the way to the base of the wing. <i>Semioscopis merriccella</i> is similar, but the bar terminates well before reaching the wing base. DISTRIBUTION: <i>Semioscopis packardella</i> is primarily found in eastern North America, but scattered populations also occur in the West, including Oregon, California, Idaho, Montana, Nebraska, British Columbia, Alberta, Saskatchewan and Manitoba. In the East, the range in Canada extends from Ontario eastward to Nova Scotia. In the US, populations occur from the northeastern states west to Wisconsin and Minnesota and southward to Iowa,Tennessee, and North Carolina. As of 2020, our only records are from two sites at lower elevations in the mountains. FLIGHT COMMENT: Local populations appear to be univoltine, with most records between March and July. A seasonal peak in activity occurs from April through June. As of 2020, our two records are from April and May. HABITAT: The specific habitat requirements are poorly documented. FOOD: The hosts are unknown, but Hodges (1974) surmised that the larvae feed on <i>Crataegus</i>, <i>Prunus</i>, and <i>Sorbus</ i> species based on the close similarity of this species to a European species that feeds on the same hosts. OBSERVATION_METHODS: The adults are attracted to lights. NATURAL HERITAGE PROGRAM RANKS: GNR SU. STATE PROTECTION: Has no legal protection, although permits are required to collect it on state parks and other public lands. COMMENTS: <i>Semioscopis packardella</i> is near the southern limit of its range in western North Carolina and appears to be uncommon in the western mountains. We need additional data on its distribution and abundance before we can assess its conservation status. March 2021 The Moths of North Carolina - Early Draft 1.

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.

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,

    TIME FOR SHIFT CHANGE IN THE FABRIC OF EXISTENCE Exploring the role of darkness and artificial light for humans and biodiversity Author: Maya Strömgren Supervisor: Mattias Sandberg Master’s thesis in Geography with major in Human Geography Spring semester 2021 Department of Economy and Society Unit for Human Geography School of Business, Economics and Law at University of Gothenburg Student essay: 30 hec Course: GEO230 Level: Master Semester/year: Spring 2021 Supervisor: Mattias Sandberg Examiner: Jerry Olsson Key words: Darkness, artificial light, light pollution, biodiversity, human- non-human relations, all-ecology, non-representational theory. Abstract This thesis departs from the loss of biodiversity due to artificial light at night. The diurnal human has taken over all hours of the day instead of the natural light once, meaning that space and time have become limited for the nocturnal living species. Earlier research concern how darkness and artificial light affect either animals, insects, and plants, or humans’ health. The combination of the two, however, remains largely unresearched. Therefore, this geographical thesis dives into this gap by exploring humans and biodiversity in relation to darkness and artificial light. Building on that exploration, the aim was further to formulate generative ways forward in the matter. A qualitative method was conducted, consisting of a self-written Darkness Diary and walking interviews with a moth-expert, a bat expert, and a light designer and light artist. The theory of all-ecology was applied as an ontological stand and a geographical toolbox. Non- representational theory (NRT) was further applied as a guide in the exploration of experience.

Peter Buchner, Scheibenstraße 335, 2625 Schwarzau am Steinfeld, Austria. E-mail: [email protected] Abstract The species Agonopterix tripunctaria sp. nov. and Agonopterix medelichensis sp. nov. are described. A. tripunctaria, pre- viously misidentified as Agonopterix nodiflorella (Millière, 1866), was recognized as specifically different by the distinc- tive male genitalia. 19 specimens have been examined, DNA-barcoding yielded full 658 bp fragment of COI from two specimens and a 639 bp sequence from a third, confirming the impression of a rather isolated species. Specimens from Italy, Slovenia, Croatia and Greece had been checked, among them one reared from Ferulago campestris. A. medelichen- sis was misidentified as Agonopterix rotundella (Douglas, 1846) in NHMV; its male genitalia are erroneously depicted as A. rotundella in Hannemann (1953) and (1995). 20 specimens have been examined, from one a 555 bp fragment of COI was obtained, confirming that it is not closely related to A. rotundella. Specimens from Austria, Italy, Hungary, Slovakia, Croatia and Greece have been checked, among them one reared from Trinia glauca, which had been misidentified as A. hippomarathri. A report of A. rotundella from Russia also belongs to this species. Key words: Lepidoptera, Gelechioidea, Depressariidae, Depressariinae, Agonopterix, Europe, new species, DNA barcod- ing Introduction Depressariidae as a family initially included the genera Semioscopis, Luquetia, Levipalpus, Exaeretia, Agonopterix and Depressaria (Depressariidae Meyrick, 1883).
  • Annotated List of the Lepidoptera of Alberta Bowman 1951

    Annotated List of the Lepidoptera of Alberta Bowman 1951

    AN ANNOTATED LIST OF THE LEPIDOPTERA OF ALBERTA1.* Abstract This list consists of 1825 species and varieties of Lepidoptera which have been taken in Alberta. Of these, 657 are records of captures in the hitherto almost completely neglected Microlepidoptera. Though few specialists on this continent have studied the taxonomy of this large group, those who have done so in certain families have generously assisted in classifying the species which are recorded. Unfortunately, in a few families it has been ilnpossible to obtain this assistance. Despite the omissions this necessitates, the list constitutes the most comprehensive catalogue of Microlepidoptera which has, up to the present, been attempted for any province in the Donlinion. Arrangement and nomenclature are based on McDunnough's Check List of the Lepidoptera of Catzada alzd the United States, published in 1938 and 1939. Proposed modifications in nomenclature, presented in subsequent publications, are substituted if they appear to be gaining general acceptance. Locality records for captures are presented by a system of ecological areas of which the chief climatological and biological characteristics are briefly described. Introductory Professional entomologists are very greatly aided in the pursuit of their lifeworlc with its practical objectives by the unstinted and critical industry of competent amateurs. Such amateurs have gathered a vast mass of data upon the distribution and the relative abundance of various insects and have recorded valuable information on the biology of the groups to which they For personal use only. have devoted their particular attention. In no field of entbmological endeavor has this been more in evidence than it is in the study of Lepidoptera.

    Moths of an Aspen Parkland Area Near Nevis, Alberta

    1 MOTHS OF AN ASPEN PARKLAND AREA 3 KM SOUTH OF NEVIS, ALBERTA, 2001-2005, 2009 update Charles Durham Bird, 15 March 2010 Box 22, Erskine, AB, T0C 1G0 [email protected] The present paper incorporates a number of redeterminations and additions to the information in the reports of 2007, 2008 and 2009. THE AREA An area of rolling Aspen Parkland 3 km south of Nevis, Alberta, was studied repeatedly from 2001 to 2005. It was an acreage owned by Allen and Laura Hall. GPS readings for the area rounded off to 52.31 N and 113.05 W with an elevation of 890 m, though Google Earth readings were 52.186 N, 113.017 W and 812 m. Moths were collected with ultraviolet light traps on 42 different collection nights, details of which appear in the Appendix. The results of this research have not previously been reported. Voucher specimens are in the BIRD Collection. 2 Map showing the location of Nevis, Erskine, Stettler and Buffalo Lake in south-central Alberta. The present study area and the Buffalo Lake Moraine Conservation Area, which is on the east side of Buffalo Lake, are both examples of native Aspen Parkland. While the grass in the acreage proper is mowed, natural areas of shrub and bush remain. The traps were in all cases set up on the edge of the property so that they would be able to sample the moths in the adjoining, lightly grazed, native aspen parkland on land owned by the Church family. On the north, there is a south-facing hillside with native grasses and forbs, including a small stand of Opuntia fragilis.
