Subfamily: Anthonominae
Genus: Anthonomus
Size: 4.5mm-6mm
Beadlike Antennae
The curculionidae family is the second largest family of beetles in North America and the largest worldwide. Curculionidae are plant feeders and some are large pests. Adult curculionidae feed on leaves, pollen, flowers, fruit and fungus and can be found on foliage and in leaf litter.
There are 166 species in the Anthonominae subfamily. A good number of those species are pests, such as the pepper weevil and the boll weevil. The Boll
Weevil causes $200-300 million worth of damage to cotton each year. Attempts to control it using insectisides have only polluted the cotton belt. Pepper weevils and strawberry weevils are also considerable pests.

Clear in the photos above is the elgonate snout characteristic of the curculionidae family. Coming out of the snout are elbow shaped, beadlike antennae with a three segmented club at the end. Its pronotum is slightly narrower at its base where it meets the elytra. The elytra are striated. Although Curculionidae appear 4-4-4-, each tarsus in fact consists of 5 segments (5-5-5).
