Notes on the biology of Aeshna sitchensis Hagen (Anisoptera: Aeshnidae)

Observations on the little-known A. sitchensis were made on Vancouver Island in southwestern British Columbia, Canada. Some details on habitat preference, male behaviour, feeding, copulation, oviposition and larval habitat are noted and some comparisons with other data are made. The species lived in bog pools that dried up in midsummer.
