Summary:A well-preserved, teneral adult female boll weevil, Anthonomus grandis Boheman (broad sense), was discovered in fragments of a cultivated cotton boll found in Guila Nacquitz Cave, Level A, dated about A.D. 900, near Mitla, Oaxaca, Mexico. This find antedates any previously known association of the boll weevil with cultivated cotton by about 900 years and negates the contention that this association began in the 18th century. The specimen is intermediate in form between Anthonomus grandis grandis Boheman and the thurberia weevil, Anthonomus grandis thurberiae Pierce.
