Dragonflies Find Crude Oil Visually More Attractive than Water: Multiple-Choice Experiments on Dragonfly Polarotaxis

Table 1. Row 1: The total number and sex (F: female, M: male) of dragonflies (Sympetrum vulgatum, Ischnura pumilio, Enallagma cyathigerum) trapped by the crude-oiland water-filled trays during the first choice experiment. Rows 2–4: The relative brightness, degree of polarization and direction of polarization of light reflected from the trays and measured by video polarimetry in the blue spectral range (lp470 nm) from a direction of view of 707 with respect to the vertical. The trays are designated by S1 and S2 as in Fig. 2
