FAUSKEl AND R. D. GUSTIN 2 ABSTRACT. Twenty-seven species of the subfamily Crambinae known as sod web­ worm moths were collected from South Dakota. A key to species has been included as well as their distribution patterns in South Dakota. This study began after damage to rangeland in several South Dakota counties in the years 1974 and 1975. Damage was reported from Cor­ son, Dewey, Harding, Haakon, Meade, Perkins, Stanley and Ziebach counties. An effort was made to determine the species of Crambinae present in South Dakota and their distribution. Included are a key for species identification and a list of species with their flight periods and collection sites. MATERIALS AND METHODS Black light traps using the General Electric Fluorescent F ls T8 B1 15 watt bulb were set up in Brookings, Jackson, Lawrence, Minnehaha, Pennington and Spink counties. In Minnehaha County collecting was carried out with a General Electric 200 watt soft-glow bulb. Daytime collecting was used in several localities. Material in the South Dakota State University Collection was also utilized. For each species a map is included showing collection localities by county.

  • Sod Webworm Pest Fact Sheet 48 Dr
    Bringing information and education into the communities of the Granite State Sod Webworm Pest Fact Sheet 48 Dr. Stanley R. Swier, Extension Specialist Emeritus, Entomology Introduction and Description Sod webworms are the caterpillar stage of small moths, from the genera Crambus and Herpetogramma. Adult moths are about 1" long, tan-colored, and are often seen flying about the lawn in jerky, short flight. Full-grown larvae (caterpillars) are 3/4" long, brown or gray with spots. The larvae construct silk-lined tunnels in soil or thatch, but come out to the surface at night to feed on grass. Life Cycle Spring: When the weather warms up, the overwintering Adult sod webworm (snout moth, Crambus saltuellus). Credit: David Cappaert, Bugwood.org. caterpillars resume feeding on grass. Damage is first observed in late-June or July. Summer: Adults or moths appear in July, mate, and lay eggs. The larvae of these moths then cause damage in August. Birds make probing holes into the turf Fall: Adults appear again in September, mate, and lay eggs.

Damage The damage caused by sod webworms shows up first as small, irregular brown patches. Flocks of birds seen on the turf are a good indicator of the presence of sod webworms. Birds make probing holes into the turf as they search for caterpillars, which can cause significant damage. Management IPM Strategies: • Monitoring - To sample for sod webworms, look carefully at the damaged area for silken tunnels. Alternatively, mix Immature sod webworm.

  • Striped Sod Wej^Worm, Crambus Mutabius Clemens1
    STRIPED SOD WEJ^WORM, CRAMBUS MUTABIUS CLEMENS1 By GKORGE G. AINSUö Entomological Assistant, Cereal and Forage Insect Investigationst Bureau of Entorno fogy, United States Department of Agriculture INTRODUCTION Throughout a wide area Crambus mutabilis is one of the most common species of the genus. It ranks well toward the head of the list in de- structiveness, although by itself it never has been directly charged with a destructive outbreak. It has not previously received detailed study, and the available information concerning it is scattered and meager. The present paper includes a summary of previously published facts, together with the results of the writer's studies for several years. SYSTEMATIC HISTORY Cr ambus mutabilis was first described by Clemens (j, />. 204)2 in i860, but he furnished no information as to the source of his material. Three years later Zeller (15, p. 44) redescribed it as Crambus fuscicostellus, a name which better characterizes the species than Clemens's adjective. Both names appear in the literature for some years, although Grote (7, p. 79) early recognized their probable synonymy. Smith ( 13, p. 87) first placed fuscicostettus unconditionally as a synonyjn of mutabilis, in which he is fully borne out by Hampton {8y p. 928), who haçi Zeller's type in the British Museum for comparison. GEOGRAPHICAL DISTRIBUTION Crambus mutabilis seevçis to be ^purely North American spçdes, for out- side of North Amgrica it ^as ^qen reported only by Hedemann, (9, p. joo), from St. Thomajs Island in the ^fest Inclies It is widespr^d over the pastern half of $he United States.

  • Lepidoptera: Crambidae) New to the Fauna of Croatia
    Acta entomologica serbica, 20 20 , 25(1): xx -xx UDC DOI: 10.5281/zenodo.3735368 THREE MONTANE GRASS MOTHS (LEPIDOPTERA: CRAMBIDAE) NEW TO THE FAUNA OF CROATIA TONI KOREN Association Hyla, Lipovac I 7, HR-10000 Zagreb, Croatia E-mail: [email protected] Abstract Three species of grass moths (Crambidae) were recorded for the first time in Croatia. Udea alpinalis and Crambus ericella were found on the peaks of Mts. Guslica and Snježnik in Gorski Kotar region, while Catoptria pyramidellus was recorded on various mountain chains across the country. The discovery of three montane species in Croatia demonstrates the lack of Microlepidoptera surveys in these areas and the need for further research. KEY WORDS : Udea alpinalis, Crambus ericella, Catoptria pyramidellus, diversity , Gorski Kotar, mountains Introduction Grass moths (Crambidae) belong to one of the best studied Microlepidoptera groups in Europe, with a surprising number of available publications (Leraut, 2012; Slamka, 2006, 2008, 2013). However, the Crambidae fauna of many countries, especially in eastern Europe, has remained poorly studied. This is easily noticeable from the distribution maps published in a book series “Pyraloidea of Europe” (Slamka, 2006, 2008, 2013, 2019). Here, the highest occurrence of species is shown for Croatia, with a very limited number of records in eastern Europe. Only recently, a tentative checklist of all Pyraloidea of Croatia was published (Gumhalter, 2019). Although the checklist is based almost entirely on published papers and the examination of several smaller collections, it is useful as a good starting point to explore the Crambidae and Pyralidae fauna of the country. 2 T.

    Section IV Cereal Crop Pests ECOLOGICAL EFFECTS OF CROWDED INSECTS IN WINTER WHEAT David Bragg, WSU Extension P O Box 190. Pomeroy WA 99347-0190 509/843-3701 [email protected] Bare spots in a winter wheat field resulting in ca. 40% loss of the winter wheat crop occurred in a field near Rockford, WA. This field was taken out of Kentucky Blue Grass last summer, (2004) and seeded to wheat using a low rate of Lindane as the seed treatment insecticide. I found a complex of insect larvae feeding on the crowns and roots of this wheat in February 2004. Wireworm larvae (Elateridae) Limonius canus LeConte were present in a fairly dense population (ca. 1 per square meter up to 3 per square meter). This alone would allow for major stand reduction. Pyralid moth larvae of the Genus Crambus, which are much larger that the Blue Grass Webworm, Crambus teterellus. I believe without having adult specimens, but with “Arnett American Insects” these moth larvae are likely to be Crambus agitatellus Clemens, the Grass Webworm, and, Crambus vulgivagellus Clemens, the Vagabond Webworm. Both are occasional pests on the crowns and roots of winter wheat and agitatellus is a cyclic species appearing under certain dry winter conditions. A significant number of maturing larvae of the Army Cutworm, Euxoa auxiliaris Grote, a common and serious pest of winter wheat, was also numerous in the field. Black Cutworm is reported to be resistant to B. bassiana and a sample will be collected to send in for pathological analysis. Any one of these three pests in the numbers present by each species could account for serious damage to the wheat stand.

  • Boughton Heath Allotment Colony: Moths in the Time of Lockdown Last Year I Started Trapping and Photographing Moths at the Colony
    Crambus perlella (Satin Grass-veneer) Boughton Heath Allotment Colony: Moths in the time of lockdown Last year I started trapping and photographing moths at the colony. I’ve continued this year, and because of lockdown I’ve done more here than anywhere else. Most of my records involve moths attracted to a light trap; I try to identify every one, photograph some and release them all unharmed. In all this year at the allotments I’ve caught and identified over 900 individual moths, belonging to 172 different species, bringing my overall total for the allotments to 194 species. This is just a brief summary of this year’s moths. There are more pictures on my Flickr site. If you follow the link, you’ll find my ‘Allotment Moths’ album, with the most recent moths appearing first. (I think the page defaults to ‘large view’ which is ok, but buttons at top right allow for a slideshow view or ‘justified view’, which I think is the best way to see the album as a whole and click through it.) https://www.flickr.com/photos/149980226@N06/albums/72157678669587018 There are moths about in every month of the year, but this year kicked off for me in March, with a handful of species, including these two Quakers. Common Quaker Small Quaker Muslin Moth Poplar Hawk- moth April highlights included Muslin Moth and Poplar Hawk-moth. Things really begin to warm up in May, both weather-wise and in the world of moths. The Green Carpet is still a common species, but what a beauty it is, likewise the Brimstone Moth.

  • Moths on Holton Lee 2017 – 2020
    Moths of Poole Harbour is a project of Birds of Poole Harbour Moths on Holton Lee 2017 – 2020 The ‘Moths of Poole Harbour’ project was set up in 2017 to gain knowledge of moth species occurring in Poole Harbour, Dorset, their distribution, abundance and to some extent, their habitat requirements. The study area uses the same boundaries as the Birds of Poole Harbour (BoPH) project. Birds of Poole Harbour recording area The ‘Livability Centre’ at Holton Lee comprises a range of habitats located on the southern side of Lytchett Bay. Open dry heath grades down to the extensively reed-fringed harbour edge through a belt of mixed secondary woodland containing a number of mature deciduous trees. An area of carr woodland is present. The ‘Flourish Garden’ contains a good source of nectaring plants. Holton Lee was visited from August 2017. 17 visits were made between 12th August and 10th October in 2017, 19 visits between May and October 2018, and 6 visits August to October in 2019. A single daytime visit was made in 2020 during the Coronavirus pandemic, but no trapping was possible. In addition, a single trapping session was held on the heath specifically targeting the Red Data Book species Southern Chestnut. Three main areas of the site were targeted for moth trapping. The primary location was the western end of the boardwalk where the woodland meets the reedbeds. A total of 32 nights trapping was undertaken in this area in 2017, 2018 and 2019. The Flourish Garden was trapped on 5 occasions in 2018 and 2019. The eastern end of the boardwalk was trapped on 4 occasions in 2017 and 2019.

By Bryan P. Pickess, 8 Shaw Drive, Sandford, Wareham, Dorset BH20 5BT C. James Cadbury, 93 Barton Road, Cambridge, CB3 9LL Summary This paper presents the results of Lepidoptera recording at the RSPB's Arne Nature Reserve, on the Purbeck Heaths of southeast Dorset, during the years 1970 – 1995. Most of the records resulted from moth trapping using a variety of lights close to the hamlet of Arne by Bryan Pickess, but sightings of butterflies and day-flying moths are included. Lowland heathland is the predominant habitat of the 501 ha reserve. A total of 34 butterfly species, 430 'macro'-moths and 366 'micros' have been recorded at Arne. They include 10 Red Data and 34 Nationally Notable 'macro'-moths. Among the 'micros' are eight potential Red Data and 27 Nationally Notable species. Of particular conservation importance among the resident heathland species are the Dingy Mocha Cyclophora pendularia, Large Bagworm Pachythelia villosella, (a psychid,) and the plume Buckleria paludum, (Small Grass Emerald Chlorissa viridata, Bordered Grey Selidosema brunnearia Ringed Carpet Cleora cinctari). The BAP Priority Silver-studded Blue Plebeius argus (a Biodiversity Acha Plan Priority Species) has many colonies on the damper heathland. The Horse Chestnut Pachycnemia hippocastanaria (Nb) can be one of the most abundant moths on the heathland.
