The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking , grasping , and holding (in probing for food, eating , manipulating and carrying objects, killing prey , or fighting), preening , courtship , and feeding young.
The term rostrum, referring to a podium for a speaker is directly derived from the use of the term "Rostra". One stands in front of a Rostrum and one stands upon the Rostra. While, eventually, there were many rostra within the city of Rome and its republic and empire, then, as now, "Rostra" alone refers to a specific structure.
A weevil's rostrum, or elongated snout, hosts chewing mouthparts instead of the piercing mouthparts that proboscis-possessing insects are known for. The mouthparts are often used to excavate tunnels into grains. [1] In more derived weevils, the rostrum has a groove in which the weevil can fold the first segment of its antennae.
They most commonly have an elongated head with a distinct narrowed 'neck', long legs, and prominent, segmented, tubular mouthparts, most commonly called the proboscis, but some authors use the term "rostrum". Most species are bright in colour with hues of brown, black, red, or orange. Nymph, found in Nepal
