Species group · Insects
WAnimals has 2 species of weevil, spread across 2 families (Attelabidae, Curculionidae).
Ranges calculated from the profiles that record the figure, not from all 2.
Each one has its own full profile. This group does not replace them: it brings them together.
No species documented in this group is genuinely at risk according to the IUCN, with the data available today.
Recorded in one country.
The male's neck is three times the length of the female's, and he fights with it.
From
The males have a neck two to three times as long as the female's, and it is she who rolls leaves into a protective nest for a single egg.
From
The male's disproportionate neck, two or three times longer than the female's, is a weapon: males shove one another with it for access to females.
From
It cannot fly: its wings are atrophied and it has entirely lost the ability to disperse on its own, so it travels only with grain moved by people.
From
Its remains have been found in Neolithic and ancient Egyptian granaries: it has accompanied agriculture since its beginnings.
From
An infested grain looks intact from the outside until the adult emerges, which makes detecting the infestation in time enormously difficult.
