Similar to other leaf beetles (Coleoptera, Chrysome-lidae), Diabrotica virgifera virgifera beetles possess tarsal adhesive setae, facilitating foothold and locomotion on various substrates, including maize host plants. However, the male-specific setae in this species, adhering to female's back, are unique (so far observed). Two seta types occur on male feet: (1) long ones with ovoid, slightly tapered terminals and basically connected shafts and (2) short ones with round terminals and centrally connected shafts. They are densely packed, forming a hexagonal pattern. The latter are indeed mushroom-shaped – as suggested for (not mushroom-shaped) male-specific setae in other beetles so far, and provide excellent models inspiring biomimetic adhesives with mushroom-shaped structures.
