OTIoRHYnCHUS RUgoSoSTRIaTUS (Goeze, 1777)

NEW BRUNSWICK: Victoria County, Four Falls (46.8390°N, 67.7332°W), 1 January 2022, J. H. Lewis, dead specimens collected from spiderwebs in private garage in agricultural area (6 adults, CMNC) .

This species is native to the western Palearctic region (Warner and Negley 1976), and is adventive in Australia, New Zealand, Chile, Argentina, and the Nearctic region ( Alonso-Zarazaga et al. 2017; Del Río et al. 2010; Kuschel 1990). In Canada, O. rugosostriatus is known from British Columbia, Ontario, Quebec, and Nova Scotia ( Bousquet et al. 2013), and also occurs widely throughout the United States of America (O’Brien and Wibmer 1982). Otiorhynchus rugosostriatus is easily distinguished from congeners in the region by characters listed in Bright and Bouchard (2008). This species is known to be parthenogenetic across much of its range ( Dieckmann 1980) and feeds on a wide variety of plants, including Cyclamen L. and Primula L. ( Primulaceae ), Fragaria L. and Rosa L. ( Rosaceae ), Ilex L. ( Aquifoliaceae ), Ligustrum L. ( Oleaceae ), and Solanum L. ( Solanaceae ); however, it is most well-known as a pest on strawberries (Warner and Negley 1976). Given the widespread presence of O. rugosostriatus in Nova Scotia and southern Quebec (Bright and Bouchard 2008), it is unsurprising that this species is also established in New Brunswick.
