Wroshyr Louse
this large, purplish-blue insect lived on the bark of the wroshyr trees of Kashyyyk. When crushed, these insects exuded a thick syrup, which was often used in Wookiee cooking. The females Wookiees of the planet belived that a young female could drop a wroshyr louse on the male they wished to court, and that the male would be bonded to her forever. Of course, the female had to offer to groom the male's fur, as a way to apologize for the "mistake."
