## Description[edit]

Arima marginata can reach a body length of about 12–20 mm (0.47–0.79 in) in females, of about 6–12 mm (0.24–0.47 in) in males.[3] Therefore this species presents a clear sexual dimorphism, as females are generally much larger than males. Moreover females outnumber males.

These beetles are shiny black with orange marginal bands on the edge of the pronotum and the elytra. Elytra cover only two abdominal segments.

Antennae are filiform and the abdomen is voluminous. The last sternites is composed by one piece, in the shape of a ginkgo leaf, while the genital plate is made of two parts.[4] These beetles do not fly, but they are very active.

## Biology[edit]

Adults of this species can be found from April to August,[5] and have one generation per year (univoltine). Adults overwinter in the ground. Female lays about 80 eggs on the leaves of the host plants, and the larvae come out after about ten days. Larvae of A. marginata can reach a body length of about 12 mm (0.47 in). They are black and highly polyphagous. They mainly feed on the leaves of many aromatic Lamiaceae species (Lavandula, Mentha, Origanum, Salvia, Basil, Thymus, etc.).[3][6]
