Kingsolver, 1972
Kiawe Bean Weevil, Bottimer's Texas Bruchid
Algarobius bottimeri is a small seed-feeding in the , Bruchinae. Commonly called the kiawe bean or Bottimer's Texas , it is associated with legume seeds, particularly those of mesquite and related plants in the Prosopis. The has been documented across Central America, North America, and Oceania, likely facilitated by human transport of seeds. Like other bruchine beetles, its develop inside seeds.

Habitat
Associated with dry, warm environments where legumes (Prosopis and related mesquites) grow. Often found in stored seeds and in field conditions where seed pods are available.
Distribution
Recorded from Central America, North America, and Oceania. The Oceania distribution likely reflects human-mediated introduction via imported Prosopis seeds.
Diet
feed internally on seeds of leguminous plants, particularly Prosopis (mesquites). may feed on pollen or not feed at all; specific adult diet unconfirmed for this species.
Host Associations
- Prosopis - larval food sourceprimary ; develop inside seeds
Life Cycle
are laid on or near seed pods. bore into seeds and complete development inside, feeding on cotyledons. occurs within the seed. emerge through round exit holes. Multiple per year possible in favorable conditions.
Ecological Role
As a seed , reduces viability of Prosopis seeds. May influence in ranges and contribute to or seed bank depletion where Prosopis is .
Human Relevance
Considered a pest of stored mesquite seeds and potentially of value as a agent against Prosopis . The "kiawe bean " reflects its association with kiawe (Prosopis pallida), an important tree in Hawaii.
