The dog owner from Midland County says now whenever the dog goes into their large lawn and adjoining two acres of un-mown turf, her nose is to the ground and she is in an aggressive hunting mode...” (J. Lindquist, Osceola County MSUE, personal communication, November 16, 2007). Au Québec, les larves matures sont grégaires et actives tard à l’automne. Caterpillars only looked dead, but they recovered and crawled away when held the hand or warmed by the sun. (Credit: E. Elsner). (Credit: J. O'Donnell). What can be done about these bugs? The initial recommendation, before we fully understood the level of cold tolerance of N. pronuba caterpillars, was to suggest no action on the part of farmers, letting a hard freeze take care of the problem. KA (Credit: N. Myers), N. pronuba caterpillars moved as a wave across this alfalfa field in Lake County, MI (A), defoliating a large area (dashed outline). Elles complètent leur développement au début du printemps. Wright (1987) anticipated N. pronuba's pest potential when he stated “careful studies of hayfield yields may reveal considerable losses due to these cutworms.”. Special thanks to Steve Passoa, USDA–APHIS–PPQ and the Ohio State University Museum of Biological Diversity, for confirming the initial identification of N. pronuba larvae. Neil Falter von Mai bis Oktober, Raupe von Herbst, überwinternd, bis Frühjahr an allen möglichen Pflanzen. Although Wright (1987) reported that larvae principally feed on grasses, the host range of N. pronuba is broad, including beets, cabbage, carrot, grape, lettuce, potato, strawberry, tomato, numerous horticultural plants, and weed species (Passoa and Hollingsworth 1996, Copley and Cannings 2005). By April 2008, defoliated turf was dead (B). The cutworm larva of the large yellow underwing (Noctua pronuba). By the middle of November, things took a bizarre turn when N. pronuba was linked to pet illness. “The picture (Fig. Copley The adult moth, 2 cm across, with brown fore-wings and yellow or orange hind wings, emerges from the shiny soil-borne chestnut brown pupa from June to July, and lays about 1000 eggs on the stems of a wide variety of weeds. Severe fall defoliation by N. pronuba in a small grain field in Michigan's Upper Peninsula resulted in stand loss in spring 2008. Interestingly, both green caterpillars and pupae were found in the spring.

Cannings 7B). The orchardgrass in the stand was only slightly touched and the alfalfa was stripped down to the ground.” (N. Myers, Oceana County MSUE, personal communication, October 12, 2007). 7A). They are in the grass by the thousands. The fed-on areas are completely dead this spring, while the rest of the field is coming out of dormancy just fine” (N. Myers, Oceana County MSUE, personal communication, April 9, 2008) (Fig. Caterpillars and Pupa (2688) butterfly caterpillars (560) brush footed butterfly caterpillars (247) Lycaenid Caterpillars (1) Skipper Caterpillars (14) Sulphur and White Caterpillars (18) swallowtail caterpillars (258) moth caterpillars (2085) Anthelidae (3) Asps and Flannel Moth Caterpillars (39) Bagworm (60) Carpenter Moth Caterpillars (4) “I have been hearing stories of Noctua pronuba feeding on cereal grains, but now I have proof. 1C). A propos des cartes. N. pronuba caterpillars were still present in this field in the soil and around weed root masses, with “4–8 larvae found under each yellow rocket plant.” Spring regrowth was delayed in defoliated areas and weeds emerged ahead of the crop. Adults are strong fliers, thus this non-native species spread rapidly across Canada into neighboring provinces (Morris 1985, 1987), then to the west coast of Canada (Copley and Cannings 2005), and southwest into the United States as far as Texas (Wagner 2005). “I live in Fife Lake Michigan and my home, garage and pole barn are being invaded by caterpillars. In small grain fields, caterpillars fed lower on the plant, at and just below the soil surface. Although alfalfa crowns survived defoliation, weeds established in the stand to compete with the crop (B). Hollingsworth Another farmer in Presque Isle County timed a caterpillar's progress over a highway at eight inches per minute, or 40 feet per hour. Noctua pronuba (Linnaeus, 1758) kingdom Animalia - animals » phylum Arthropoda - arthropods » class Insecta - insects » order Lepidoptera - butterflies and moths » family Noctuidae - owlet moths » genus Noctua - fruit-piercing moths Scientific synonyms. Growers applied pyrethroids well into November and reported excellent control. In spring 2008, extension staff and producers returned to fields to survey the damage. The forewings are long, narrow and rounded. This apparent cold tolerance has earned the larval stage of N. pronuba the unofficial common name ‘winter cutworm’ in Michigan. It's just way behind and weeds are going to get a jump on the crop. The caterpillars are named cutworms, because they damage plants by chewing through the stems, cutting them at the base. Author: Jan Zima. The first moths collected in North America were found in Nova Scotia in 1979, and this species has since spread across Canada and the United States. Another extension educator in the Upper Peninsula of northern Michigan walked a 1-yr-old seeding and said “The stand doesn't seem so bad. The first instar caterpillars, having fed on weeds, descend to the soil and in the later instars cause the damage described above, eventually reaching about 3.5 cm in length. In Axel Steiner und Günter Ebert: Die Schmetterlinge Baden-Württembergs Band 7, Nachtfalter V (Eulen (Noctuidae) 3.Teil), Ulmer Verlag Stuttgart 1998.ISBN 3-8001-3500-0, p. 359ff three phenotype are described for both sexes..

Etat carte : à jour. 5A) shows feeding damage on the edge of an adjoining field of alfalfa and volunteer oats that they started to move into. Project Noah is a tool that nature lovers can use to explore and document local wildlife and a common technology platform that research groups can use to harness the power of citizen scientists everywhere.

One educator coined the term ”scalping' to describe this feeding. Caterpillars climbed plants (A) to feed on leaves and small petioles, stripping plants bare (B). KA From the outbreak in 2007 and 2008, we determined that under heavy infestation, N. pronuba is an agricultural pest in alfalfa, mixed hay, and small grain fields. The field was sown last fall and the headed rye was mowed down in August of this year to reseed it. But by afternoon they shrink in size.” (P. Durst, Oscoda County MSUE, personal communication, November 14, 2007). Adults are easily recognized by a showy orange hind wing bordered by a black bar (Fig. N. pronuba was confirmed, or in some cases presumed to be, the cause of pet illness as the only species still active in November. The farmer said within a day of moving into this field, they reversed course and headed to his white plastic Ag-Bags of stored silage (Fig. Wright The term ‘cutworm’ refers to the habit that these worms have of chewing right through the stem of a plant. 1B). The authors developed a two-page diagnostic bulletin for N. pronuba, and MSU extension offices provided this handout to veterinarians in northern counties to make them aware of the potential problem.
