Stored Product Pests
Most characteristic is the long anteater-like 'snout' at the front of its head, with a pair of chewing mandibles on top. The male's snout is shorter, wider, and more distinctly punctuated than the female's. Adult's elytra (forewings) usually have four, faint, red to yellow spots, and wings are used for flight. There are deep pits on the thorax that are round or irregular-shaped. The midline of the pronotum (top body plate) is usually puncture-free. Larvae are legless and fairly smooth. They look more humpbacked than anteater-like, and are thicker in the middle. There are 7-8, tiny, fingerlike sensory projections on the lower mouthpart.
They are believed to have originated from India, where there is plenty of rice. They are now all over the world, especially warm climates. In the U.S., they are common in field and stored grain.
As with most insects, they like to stick close to their food source (either in or near it). I suppose we're not much different.
Work well on a raw-food diet. Includes corn, wheat, rice, rye, buckwheat, cereals, beans, nuts, cotton, grapes, apples and pears. You may find 'surprises' in your breakfast cereal that are truly surprises if left neglected too long.
Larvae must raise themselves in their own grain of rice. Females lay eggs in single grains by boring a hole inside. She lays 300-400 eggs in her lifetime, but seldom in winter, as egg laying decreases with temperature. The grain is then sealed off with a gelatinous material after eggs are laid. Larvae go through 3-4 instars (stages) in about 18 days, then pupate for 6 days. Adults aren't ready to leave the nest just yet, but at least they aren't mooching off mom and dad; they remain another 3-4 days to ensure they are hardened and mature. Life span varies; in summer it can be as short as 32 days, but adults can live for 3-6 months.
A plague upon crops and stored grain.
A vicious cycle: insects fly from stored grain to crops in the field, which in turn go into storage, continuing the infestation in a potentially endless cycle. Adults are also attracted to light.
