(3691) H1SADA, M., 1972. Azimuth orientation of the dragonfly (Sympetrum). In: S.R. Caller, K. Schmidt-Koenig, G.J. Jacobs & R.E. Belleville, (Eds), Animal orientation and navigation, pp. 511-522, U.S.Govt Printing Office, Washington D.C. — (Inst. Zool.,Fac. Sci.,Hokkaido Univ.,SapporoJA). Based on observations of S.frequens, S.darwinianum and S. infuscatum, evidence is presented of directional orientation of the alighting adult dragonfly relative to the azimuth of the Sun, and an indication is given of the contribution of the wind direction to this orientation. Some preliminary experiments to find a possible operative receptor for this orientation are also noted.
