Cylindrocopturus eatoni is a species of weevil commonly found in Oregon. The adults of the species are black and densely covered with grayish scales. The species is a good flier, but it often hops when disturbed, which is why it is often mistaken for a leafhopper. It lays its eggs singly in niches excavated in the bark of a main stem and its twigs.
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.
Female weevils have the ability to reproduce parthenogenetically [2] with fertilisation of eggs required to produce males, though no males have been observed. [3] This form of parthenogenesis is known as thelytoky. Grubs grow up to 1 cm in length, have a slightly curved, legless body and are creamy white in colour with a tan-brown head.
Hylobius abietis or the large pine weevil is a beetle belonging to family Curculionidae. This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations.
Gonipterus platensis is a species of weevil in the family Curculionidae.It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil.It feeds and breeds on Eucalyptus trees and is endemic to Australia, though it is also found in New Zealand, North America, Hawaii, and western Europe.
Gonipterus pulverulentus is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil. It feeds and breeds on Eucalyptus trees and is endemic to Australia, though it is also found in South America. [1]
Curculio glandium eggs are deposited in acorns by the adult weevil chewing channels into the fruit. The eggs are then released using an ovipositor, a long, narrow organ featured in female weevils. [2] These do not reach the acorn's embryo and are healed by the plant, sealing the holes and protecting the eggs from parasites.
Nemonychidae is a small family of weevils, placed within the primitive weevil group because they have straight rather than geniculate (elbowed) antennae. They are often called pine flower weevils. As in the Anthribidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting. Nemonychidae have ...
