weevil

[wee-vuhl]
or snout beetle

Any of about 40,000 beetle species in the largest family of beetles, Curculionidae, which is also the largest family in the animal kingdom. Most weevils have long, elbowed antennae that may fold into special grooves on the prominent snout. Many species are wingless. Most species are less than 0.25 in. (6 mm) long, are plainly coloured and marked, and feed exclusively on plants. Some species are more than 3 in. (80 mm) long. The larvae may feed on only a certain part of a plant or a single plant species; adults are less specialized. The family includes many destructive pests, including the boll weevil.

Boll weevil (Anthonomus grandis)

Small beetle (Anthonomus grandis) found almost everywhere cotton is cultivated. It is the most serious cotton pest in North America. Adults vary in size according to how much food they received as larvae, but they average about 0.25 in. (6 mm) long, including the long, curved snout. In the spring adults deposit eggs in cotton buds or fruit. After hatching, the larvae live within the cotton boll, destroying the seeds and surrounding fibres. Because the larvae and pupae remain inside the cotton bolls, they cannot be killed with insecticides. The boll weevil destroys an estimated three to five million bales of cotton annually.

A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. The snout is also often called a muzzle. A piece of equipment also called a muzzle can be placed over the snout to prevent the animal from biting or eating, often used before and after horse races (see animal muzzle).

A wet snout nose is called a rhinarium.

Dog's muzzle

Dogs' muzzles range in shape from extremely long and thin (dolichocephalic), as in the Rough Collie to nearly nonexistent because it is so flat (extreme brachycephalic), as in the Pug. Some breeds, such as many sled dogs and Spitz types, have muzzles that somewhat resemble the original wolf's in size and shape, and others in the less extreme range have shortened it somewhat (mesocephalic) as in many hounds.

The muzzle begins at the stop, just below the eyes, and contains the dog's nose and mouth. Most of the dog's upper muzzle contains organs for detecting scents. The loose flaps of skin on the sides of the upper muzzle that hang to different lengths over the dog's mouth are called flews. The snout is considered a weak point on most animals, because of its structure an animal can be easily stunned or even knocked out by applying sufficient force.

It is innervated by one of the twelve pairs of cranial nerves. These nerves start in the brain and emerge through the skull to their target organs. Other destinations of these nerves are eyeballs, teeth and tongue.
