Drawing setae: a GNU way for digital scientific illustrations

Abstract

In a recent paper (2015) I proposed a method to draw accurate line drawings for taxonomic studies, using taxa from Oniscidea. To complement that work, this short communication proposes a free-hand way to quickly draw areas with small setae or hairs, such as in penicils of mouth parts. This method enhances the previous drawing procedure, it takes a brief practice time, and allows a better quality of scientific illustrations.
