Summary Forty‐three species of Plecoptera were collected from emergence traps in an Oregon woodland stream. Adults occurred during every month of the year, but the largest numbers and most species emerged from April to June. Temporal separation of con‐generic species occurred within the suborder of Filipalpia, but not in Setipalpia. Some species of Nemoura had split emergence periods. The onset of emergence for a species from year to year generally varied by less than 2 weeks. Peak emergence occurred at least 1‐2 weeks after the start ofthe emergence period.
