File:Fig FlagellumCuticle.jpg
Summary
Schematic longitudinal section through the Flagellum of the stick insect antenna (Carausius morosus). Top: The flagellum has a two-layered cuticle, where the outer layer, the exocuticle (orange), is hardened and stiffenned through sclerotisation, and the inner layer, the endocuticle (blue) is softer, more elastic and has a much higher water content. As the diameter of the flagellum tapers, the soft endocuticle gets thinner and thinner. As a result, the fraction of cross-sectional area filled by endocuticle gets less from base to tip, much like the damping properties change from strongly overdamped at the base to slightly underdamped near the tip. Note that the diameter is enlarged 10-fold relative to the length. Bottom: True proportions of the Flagellum. TS: Location of the temperature sensor. [adapted after Dirks and Dürr, 2011, J. Mech.
