Cultus sp. (Perlodidae) .

Two Cultus species have been listed from northeastern North America: C. d. decisus (Walker) and C. verticalis (Banks, 1920) (DeWalt et al. 2018, Myers & Kondratieff 2009, Stark et al. 1988). Cultus d. decisus (Walker, 1852) has been found in north-central New Brunswick (Giberson & Garnett 1996) and C. verticalis has been reported from Quebec and the eastern seaboard of the USA (Myers & Kondratieff 2009). The larvae of C. d. decisus prefer larger streams and rivers, while those of C. verticalis are found more commonly in small to medium sized streams (Myers & Kondratieff 2009). Two adult Cultus sp. were collected from a single small, headwater stream (site 3) during this survey and a Cultus sp. larva was collected from a nearby stream. The adults were sent to Boris Kondratieff who recommended that they be listed as Cultus sp. and that the larva be identified to Cultus / Isoperla . More material is needed to provide a specific determination.
