Classification:
Cassida vibex belongs to the subfamily Cassidinae, tribe Cassidini.
Distribution:
Europe; in parts of Asia.
Habitat:
In all types of grassland in warm and low locations.
Description:
Size 5.5 - 7 mm; elytra and pronotum form a broad shield covering the body; pronotum with angled corners; upper side green to golden brown; basal triangle and central seam line of elytra reddish brown; distal antenna segments black; femora black on most of their length, often only the tip light.
Similar species:
Similar species occurring in Central Europe are Cassida bergeali and Cassida pannonica. They prefer to live in warmer and drier habitats.
Biology:
Cassida vibex is an oligophagous species living mainly on thistles and knapweeds, but also on burdocks and artichokes. The beetle shown here was found at the edge of a damp meadow on a cabbage thistle (Cirsium oleraceum).
The females of Cassida vibex mate from April. From May to July the eggs are laid individually or in small groups of up to 7 on the undersides of leaves and covered with faeces. After 6 - 10 days the larvae hatch. They feed on the leaves of their host plants. For their protection they bear a shield of faeces and stripped off larval skins. About 8 days after pupation, the new generation hatches, which hibernates in the foliage layer or on the ground after a maturation feeding in late summer.
Natural enemies:
Known parasites of Cassida vibex are the chalcid wasps Brachymeria vitripennis (Chalcidididae) and Aprostocetus (Aprostocetus) bruzzonis (Eulophidae).
