Larinus onopordi explained

Larinus onopordi, also known as the globe thistle capitulum weevil, is a species of true weevil in the genus Larinus.[1] [2]

Range

This species is found in regions surrounding the Mediterranean Sea.[3]

Ecology

Larinus onopordi is univoltine, undergoing one generation per year. Females lay eggs in the capitulum (flowerhead) of globe thistles, mainly Echinops sphaerocephalus, Echinops orientalis and Echinops pungens.[3] [4] [5] Larvae develop in the capitulum, eating and destroying the seeds. Pupation occurs in late summer, and a new generation of adults emerge after a few days.[6]

The braconid wasp Bracon facialis has been reared from the pupal stage.[7]
