Larinus is a genus of true weevils, comprising about 180 species, mostly in the Palaearctic region with some species introduced to North America. Turkey appears to have a significant diversity of the group, with more than 50 species recorded in the eastern part of the country. ::figure[src="https://upload.wikimedia.org/wikipedia/commons/7/71/Canada_Thistle_Bud_Weevils_(Subgenus_Phyllonomeus)_Mating.jpg" caption="Canada thistle bud weevils (subgenus ''Phyllonomeus'') mating" alt="Canada Thistle Bud Weevils (Subgenus Phyllonomeus) Mating"] ::

Several of these beetles are used as agents of biological pest control against noxious weeds. They feed on flower heads, destroying the developing seeds of the weeds.

Description

In simple terms, Larinus are black weevils with stocky bodies. They are rounded and slightly oblate dorsoventrally. They are covered in sparse hairs.

According to a more detailed description, Larinus are stocky in shape unlike the related genus Lixus. The rostrum is almost always shorter than the pronotum or as long as the pronotum. There are antennal furrows on the rostrum and these do not extend forward to the tip. The eyes are flat or slightly bulging. The pronotum is always transverse and strongly narrowed towards the front. On the sides of the pronotum are light gray or yellowish hairs. The elytra are short, usually about 1.5 times as long as their total width. The apices of the elytra are rounded together. In fresh specimens, the elytra are mottled with irregular patches of pale hairs. The legs are short and robust.

Ecology

Larvae of Larinus live in flower heads of plants in the family Asteraceae. They consume ovarioles, achenes and receptacle tissue. They also pupate in flower heads. Adults feed on leaves, stems, flowers, buds, peduncles and possibly pollen of their host plants.
