Fig. 3 in Ultrastructure of attachment specializations of hexapods (Arthropoda): evolutionary patterns inferred from a revised ordinal phylogeny

Fig. 3. Diversity of the leg attachment devices (gray­colored areas) in hexapods. (a) Arolium (smooth). (b) Pulvilli (smooth or hairy). (c) Empodial pulvillus (ep) (hairy). (d) Hairy adhesive soles of tarsomeres. (e) Eversible pretarsal bladder (smooth). (f) Eversible structure between tibia and tarsus (smooth). (g) Fossula spongiosa (hairy). (h) Euplantulae (eu) and claw pad (cp) (both smooth). (i) Tarsal thorns transformed into adhesive structures (th), claw pad (cp) (both smooth). (j) Adhesive claw setaePublished as part of R. G.
