Arboreal Ants Use the “Velcro® Principle” to Capture Very Large Prey
(A) Scanning electron micrograph of the hook-shaped claws of A. andreae workers. (B-C) Photomicrographs of unstained, 50 µm sections of Cecropia obtusa (B) and C. palmata (C); the upper side of the lamina is on the top. D-G- Scanning electron micrographs of the upper side (D–E) and underside (F–G) of the lamina of C. obtusa (D–F) and C. palmata (E–G). Long, thin trichomes characterize the underside of the leaves of both species, but with major differences in densities; whereas the upper surface of the leaves has short, wide trichomes – here, too, at different densities. Scale bars, 100 µm.
