Phyllobius pomaceus · dilgėlinis lapinukas

The species is distributed in Europe and Asia as far as Siberia and occurs in the north as far as central Fennoscandia and is also widespread in the British Isles. The species is very common in central Europe, but is absent in the Mediterranean region.

Phyllobius pomaceus is a slender and elongate weevil, measuring 7–9 mm in length with bright metallic green scales, combined with variations of gold, blue and copper colour, on its elytra. Larvae measure up to 8 mm in length, with a creamy white coloured body and dark head.

The beetle is associated with nettles (Urtica dioica) and Meadow Sweet (Filipendula ulmaria). P. pomaceus can also be a pest of strawberries. Larvae live within the soil feeding on roots, adults above ground on the leaves and stems of their host plants.

Vabalai ryškiai žalios spalvos su gana storu ir trumpu straubliuku. Jie maitinasi įvairių lapuočių medžių lapais, dažnai apgraužia braškių lapus. Patelės kiaušinėlius deda į dirvą krūvelėmis po augalų liekanomis. Lervos baltos, raukšlėtos, sulinkusios, be kojų, tamsia galva. Jos gyvena dirvoje ir dažnai apgraužia braškių šaknis. Pasimaitinusios lervos lieka žiemoti dirvoje.
