The bean weevil was described as Bruchus obtectusby Thomas Say in 1831 from specimens taken in Louisiana.

The first economic record of this insect was by Asa Fitch of New York who received infested beans from Providence, Rhode Island in 1860.

In 1891, J. A. Lintner, New York, proved that the bean weevil bred continuously in stored beans, thus differing from the well-known European pea weevil. This weevil was introduced into California by the Mission Padres with the founding of the first Mission at San Diego in 1769.

Red lima beans taken from the ancient Indian graves in the valley of Ica and the Anc6n Necropolis in Peru show the work of the bean weevil. Ica records date from 1-500 A.D., whereas those of Anc6n are more recent, 1000-1500. However, both antedate the arrival of the Spanish in Peru. An adult bean weevil taken from the Anc6n beans does not differ in anatomical characteristics from the bean weevils of today.
