The ore-colored alder leaf beetle ( Plagiosterna aenea syn. Linaeidea aenea ) is a beetle from the family of leaf beetles (Chrysomelidae).
description
The very variably colored beetles have a body length of 6.5–8.5 mm. The color ranges from metallic green to shimmering green gold, often blue, more rarely red gold. The first to sixth antenna elements are at least partially colored yellow-brown. The dark legs of the beetles have a metallic sheen. The pronotum is narrower than the wing . It has no offset side bulge. The puncture of the pronotum is fine in the middle and coarse on the sides. The wings have a strongly protruding shoulder bulge. The tibiae have an imperfect groove on the outer edge. The third tarsal link is weakly cut out at the tip.
Similar species
- Blue alder leaf beetle ( Agelastica alni ) - wider pronotum without protruding corners
- Green sorrel beetle ( Gastrophysa viridula ) - poorly developed shoulder bumps
- Broad willow leaf beetle ( Plagiodera versicolora ) - clearly rounder shape
distribution
The ore-colored alder leaf beetle is a Palearctic species. The beetle species is found in Central and Northern Europe, while it is absent in the Mediterranean region. In the north, their occurrence extends to the British Isles and in Scandinavia to the north of the Arctic Circle . In the east the distribution area extends over Siberia to the Far East of Asia (China, Korea and Japan).
Way of life
The beetle species uses various alder species ( Alnus ) as host plants , in particular black alder ( Alnus glutinosa ) and gray alder ( Alnus incana ). The females each lay several eggs on the underside of the leaves of the trees. The hatched larvae feed on the leaves. They become 9–12 mm long. The adult beetles can be seen from April to August. These are often found on alders and in wet meadow biotopes . The species overwinters as an imago .
Taxonomy
The species was first described by Carl von Linné in 1758 as Chrysomela aenea .
