Caused By:-     Various species of Cionus Beetles


Cionus olivieri. The figwort weevil adults often looks like bird droppings from afar and has a brown/black body and a grey haired head and thorax and about 5mm long. There are one or two velvety black spots on the wing-cases, one in front of the other in the middle. There are several species of Figwort Weevils (Cionus species) and the colouration differs slightly. The most common in the UK is Cionus scrophulariae. The larva stage does the most damage and looks like small slimy black slugs, much like the Lily beetle larva. These are usually distasteful to predators. The larva eat the leaves, usually at the growing tips, causing the leaves to dry up. When fully grown the larvae spin spherical cocoons on the plant stems within which they pupate. The cocoons closely resemble the seed pods of figwort. They also feed on other Genus of plants apart from Figwort. Adult weevils overwinter in the soil and leaf litter and emerge around May to lay eggs. There can be two generations during Summer between May and September.Picture from Wikimedia Commmons.
