  1. 1. Flower Cues for Hawkmoths: Colour, Place and Odour

    Författare :Anna Balkenius; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoologi; Zoology; olfaction; vision; learning; multimodal; Macroglossum stellatarum; Hawkmoth; Deilephila elpenor;

    Sammanfattning : Flowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D.
