Rugilis ceylanensis (Kraatz, 1859)†

Material examined.

New Brunswick, York Co., Charters Settlement, 45.8395°N, 66.7391°W, 20.VIII.2006, 22.VIII.2006, 26.IX.2007, 23.IX.2009, 1.X.2009, R.P. Webster // Mixed forest, in decaying (moldy) corncobs & cornhusks (2 ♂, 8 sex undetermined, RWC).

Distribution in Canada and Alaska.

ON, QC, NB ( Bousquet et al. 2013). Rugilus ceylanensis occurs in the southern and eastern Palaearctic and Oriental regions, New Guinea, and Hawaii where it is adventive ( Hoebeke 2010, Assing 2012). Hoebeke (2010) reported this adventive species for the first time for North America from several states in the USA, and ON and QC in Canada.

Natural history.

All specimens of Rugilis ceylanensis from NB were collected from a pile of decaying moldy corncobs and cornhusks. Elsewhere in the USA and Canada, this species was found in leaf piles, rotten leaves and logs, detritus, horse dung, and carrion ( Hoebeke 2010), and at the edge of an orchard growing apples, pears, and plums (coll. C. Lévesque). In Europe, adults were found in compost heaps, mammal dung, carrion, and along lakeshores and riverbanks ( Assing 2012).
