Coccinella septempunctata, the common ladybug, the seven-spot ladybird (or, in North America, seven-spotted ladybug or "C-7" [1]), is a carnivorous beetle native to the Old World and is the most common ladybird in Europe. The beetle is also found in North America, Central and Eastern Asia and regions with a temperate climate.
After hatching, the larvae will begin eating, including the other eggs in their clutch. [7] Certain species lay extra infertile trophic eggs with the fertile eggs, providing a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. [41]

They also eat pollen which may constitute up to 50% of their food intake, [3] nectar, water and honeydew. When normal prey is scarce, both adults and larvae sometimes exhibit cannibalistic tendencies, eating eggs, larvae and pupae of their own species.

The boll weevil (Anthonomus grandis) attacks cotton crops; it lays its eggs inside cotton bolls and the larvae eat their way out. Other weevils are used for biological control of invasive plants. A weevil's rostrum, or elongated snout, hosts chewing mouthparts instead of the piercing mouthparts that proboscis-possessing insects are known for.
Weevils also are known to infest oats, rice, corn, corn meal, sorghum, and cereal, so you might want to apply the same practice you do to your flour as those items as well.
