Rhyssomatus lineaticollis (Coleoptera), are weevils that primarily feed on the stems of A. syriaca. Adults initially feed on the apical leaves and then, after feeding, female weevils walk to lower parts of the stem and chew several sequential holes in the stem, creating a continuous scar. Females lay a single egg per hole and larvae complete development inside the stem while feeding on pith tissue. Oviposition scar length is an accurate predictor of the number of eggs laid by the adult female. (Agrawal, 2005)
