Plants most commonly attacked by figwort weevil include Phygelius, Buddleja globosa, Scrophularia and Verbascum.
- Several species of weevil (Cionus species) cause partly eaten and dried up foliage, particularly at the shoot tips. There is also likely to be damage to the flower buds
- The adult beetles are black and greyish white and are up to 4-5mm (about 1/8in) long, with one or two black circular marks where the wing cases meet
- The larvae are up to 6mm (about ¼in) long and are slimy, yellowish-brown grubs with black heads
- The larvae feed on leaves by grazing the surface of the leaf. The remaining damaged tissues dry up and become brown or white
