TSN 568635 NotesThis animal is not reported from Gunnison County. It was described from a site at 11,000 feet near Chasm Lake, Colorado. At high elevations, watch for small Ephemerella adults that are similar to E. aurivillii.LinksOn this website:Introduction to the Ephemerellidae Other Websites: Photos, Map, Taxon Identifier Numbers - from the Global Biodiversity Information Facility Ephemerella apopsis at Gbif ReferencesJacobus, LM and McCafferty, WP 2008 Revision of Ephemerellidae genera (Ephemeroptera).

PDF - caution 46MB Quote from page 27: "Remarks: The single type record is the only known record for this species. This species is related closely to the eastern species, Draeconia needhami McDunnough (Jacobus and McCafferty, 2008), and may possibly be a variant of this species (McCafferty, 1992). McCafferty (1992) also adds that it is odd that there are no other records of this species available considering the amount of benthic studies that have occurred in Colorado. Additional effort targeting the type locality and similar habitats is needed to confirm the taxonomy, existence, and distribution of this species. Currently (2010) this species is considered valid and endemic to Colorado and the SPRB (McCafferty, 1992)." The elevation collected is 11,000 feet and the adults emerged in July. |
