Hair base

Caption

Scanning Electron Microscopy (SEM) image of the bases of pretarsal (ie, on lowest part of leg) adhesive hairs. (A) On the left are the hair shafts of the adhesive hairs closest to the exoskeleton. At their insertion, the hair shaft becomes thinner and a stopper-like structure on the exoskeleton meets and attaches to it. (b) Further magnification of the same region: the asterisk marks the pivot point where hairs can bend upwards. Distal vs. proximal here means away from vs. towards the claw on the tip of the leg.
