Figure 1

SEM images of wax producing and wax collecting sites in Trialeurodes vaporariorum. (a) Wax plate. (b) Rows of microtrichia arranged in groups of three on the surface of the wax plate. (c,d) Wing surface covered by acanthae collecting particles in multiple layers and mechanically fastening them to the surface. (e) The dimensions of the wax particles are defined by the dimensions of the templates from which they are extruded. (f) Reconstruction of the curved, three dimensional shape of wax particles after they are shaven off the abdominal plates. Data are means ± standard deviation (N = 18 measurements). Roman numerals indicate corresponding template and particle structures. The models in e and f are created with SketchUp® (Trimble Inc., Westminster, Colorado, U.S.).
