• Chrysolina fastuosa Scop. (Coleoptera, Chrysomelidae) having hairy adhesive pads on various (among them twelve waxy) plant substrates have shown that Acer negundo L.

In common with most beetles from the family Chrysomelidae [37], this species has hairy tarsal adhesive pads (according to

For these experiments, female Colorado potato beetles (Leptinotarsa decemlineata, Coleoptera: Chrysomelidae) with hairy tarsal attachment system were used as model insect species. The beetles were collected from an organically farmed potato field in Kirchzarten area near

In smooth insect pads, the pad secretion consists of a water-soluble and a lipid-soluble part [254]. Data obtained from shock-freezing, carbon–platinum coating, and replica
