Glocianus
minute seed weevils
Glocianus is a genus of minute seed weevils (Curculionidae) comprising approximately 15 described species. The genus is primarily known through detailed study of G. punctiger, a specialist herbivore associated with dandelion (Taraxacum officinale). Larvae develop within dandelion inflorescences, feeding first as internal stalk borers then as seed predators in flowerheads before pupating underground. The genus serves as a model system for studying tritrophic interactions and urban ecosystem dynamics.
