Fig. 8. Examples of force–distance curves obtained by adhering trichomes of Roridula gorgonias to the ventral surface of the abdominal cuticle of living insects. The curves were used to calculate the work (shaded areas) that had to be applied to retract the adhering trichomes to a distance of 1.5 mm. (A) Data obtained on Pameridea roridulae. (B) Data obtained on Calliphora vicina.
