Nausibius clavicornis
Nausibius clavicornis is a cosmopolitan silvanid flat bark beetle known primarily as a pest of stored sugar products. It is frequently recorded from sugar commodities and has been most commonly collected from sugar in Trinidad, where it appears restricted to this substrate. Under laboratory conditions, development from egg to adult averages 30 days. The species exhibits relatively high fecundity and adult longevity, with females living up to 163 days and producing an average of 275 eggs. However, it is unlikely to multiply rapidly in raw or unrefined sugar, and any deterioration it causes in stored products is minor compared to other factors.
