Description
Smaragdina affinis, dorsal view

The adults are 3.5–4 millimetres (0.14–0.16 in) long. Head is shiny black. Elytrae are black, with bluish reflections. Pronotum is edged with orange-red or red-brown, while the disc is black. Pronotum shows a fine and sparse punctuation, with strong and dense punctuation on the elytrae. Tibia and tarsi are orange. Femurs are hardly darkened at the base.[4]

Biology

Adults mainly feed on leaves of Corylus avellana, Quercus and Crataegus species, while larvae possibly feed in leaf litter.[5]

Distribution

These leaf beetles are present in most of Europe.[1][6]

Habitat

These leaf beetles are heat-loving. They can be found predominantly in thickets and forest edges, in the plane or on dry warm slopes, from about April to July.
