Gray-green thigh beetle ( Oedemera virescens )

Green longhorn beetle ( Oedemera nobilis )

Common longhorn beetle ( Oedemera femorata )

The horned beetles , thigh beetles or narrow-ceiling beetles (Oedemeridae) are a family of beetles . They occur worldwide with about 1,500 kinds. In Europe, 122 species and sub-species occur in Central Europe there are about 30 species.

features

The beetles vary in body length from 5 to 22 millimeters. They look similar to longhorn beetles and have an equally elongated body that is soft and not so strongly chitinized. They are predominantly yellow and black, or metallic green, green, blue or black-blue in color. The pronotum , which is significantly narrower than the wing , is colored differently in some species than the rest of the body and can differ from one another in males and females. The deck wings are gaping at the back of some species and ribbed in many species. The antennae are usually thread-shaped and have 11 links. There are seldom species in which they are sawed, some males also have 12 antennae. The compound eyes are usually indented by the feeler deflections. The long and weak legs have 5 tarsal links in front and in the middle , and only four in the back. The first tarsal link is long and usually one or two links have lobed widenings. The thighs (Coxae) are thickened club-shaped in the males of many species.

Occurrence

The animals occur worldwide. They live in forests and on their edges, on meadows and also in gardens and often sit on the flowers of bushes and herbaceous plants.

Way of life

The adults feed on pollen . Some can be attracted by artificial light at night. The larvae develop in all types of wood or in dry stems of herbaceous plants. There are species that can even live in driftwood. The animals overwinter as dolls in the doll's cradle.
