The influence of food supply on foraging behaviour in a desert spider

  title={The influence of food supply on foraging behaviour in a desert spider},
  author={Yael D. Lubin and Johannes R. Henschel},
We tested the alternative hypotheses that foraging effort will increase (energy maximizer model) or decrease (due to increased costs or risks) when food supply increased, using a Namib desert burrowing spider, Seothyra henscheli (Eresidae), which feeds mainly on ants. The web of S. henscheli has a simple geometrical configuration, comprising a horizontal mat on the sand surface, with a variable number of lobes lined with sticky silk. The sticky silk is renewed daily after being covered by wind… CONTINUE READING
