Pteronarcys pictetii Hagen View in CoL .

This species is widespread in midwestern North America and extends westward to Colorado, South Dakota, and Manitoba ( Nelson 1971). Frison (1935) listed this species as P. nobilis (Hagen) . Frison (1937) later found the type of P. nobilis actually represented P. dorsata and that all adult Illinois specimens known at that time belonged to P. pictetii . DeWalt GoogleMaps et al. (2005) accepted that this is still the only Pteronarcys species in Illinois. Grubbs (2004) named six counties where the species had been found in Indiana, mostly in the White GoogleMaps and Wabash River GoogleMaps drainages.
