Sexual dimorphism in the attachment ability of the Colorado potato beetle ... to rough substrates
By D. Voigt, J. M. Schuppert, S. Dattinger, and S.N. Gorb
Elsevier Ltd., 2008
Sexual dimorphism in the attachment ability of the Colorado potato beetle Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) to rough substrates, Journal of Insect Physiology, Volume 54(5): 765-776, 2008.

L. decemlineata has myriad deformable setae on its tarsi which allow it to adhere to rough surfaces due to van der Waal's force. Deformation of the setae and adhesive secretions allow for a greater contact area, enhancing the bond.

Abstract

In this study we use a combination of morphological, molecular (mtDNA cytochrome c oxidase subunit 1 gene), geographic and ecological (field observations and cpDNA sequences from ingested plant tissue) data to describe and diagnose a new southern Nearctic leaf beetle species of Calligrapha Chevrolat, 1836 (Chrysomelidae: Chrysomelinae): [b]Calligrapha thermalis Gomez-Zurita, sp.
