Weevils
Updated: 22 Jul 2021
Description:
Weevil species are found in a wide range of colors and body shapes. Many are slender or oval-shaped insects. Depending on the species, weevils vary in size from about 3 mm to over 10 mm in length. They are usually dark brown to black in color. Some have scales or shiny hairs covering part of their body. The most distinctive feature of weevils is the shape of their head. An adult weevil has an elongated head that forms a snout. The mouth is at the end of the snout. Some weevils have a snout that is as long as the body.
Habits:
Like their appearance, weevil habits also vary among species. Some lay their eggs in the spring near the host plant, the larvae hide underground and feed on the roots of the plant. Some larvae will remain underground through the winter and surface as fully grown adults in the spring. They feed on plants in both the larval and adult stages. They can be extremely detrimental to crop livelihoods. Some weevils also attack stored grains and seeds, the most common of which is known as the rice weevil.
Defense:
Weevils can be difficult for a homeowner to recognize when they are on the outside of the home. However, once this pest finds an entry point into the home, homeowners will often find hundreds of them crawling on walls and other surfaces.
- Most likely, homeowners who see weevils are dealing with the stored product species.
- Careful inspection of items prior to purchase can help prevent re-infestation. Products with holes or signs of damage in the packaging should not be purchased.
