Färgval hos blomkrabbspindeln (Misumena vatia) med och utan konkurrens
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can be both white and yellow (could also change colour) and it was here examined whether individuals preferred to sit on flowers which has the same colouration as their bodies. I found that M.vatia showed preference for flowers that matched their own body colour, but when competition was introduced this preference disappear. It seems, however, that position is a factor that can influences the substrate decisions of M. vatia, where the edge of the flower is preferred.
