The willow-line Bock , Red-necked pastures Bock , Red-necked line Bock or Colorful line Bock ( Oberea oculata ) is a beetle from the family of longhorn beetles (Cerambycidae).
features
The beetles are 15 to 21 millimeters long and cylindrical. For longhorn beetles, their bodies are very narrow and the color is reminiscent of the common soft beetle ( Cantharis fusca ). The abdomen, legs and pronotum (with two small black dots) are orange-red. The head, antennae and elytra are black, but the latter appear gray with small black dots due to their hairiness. The antennae are also finely haired in gray and are rather short for longhorn beetles, as they do not reach the end of the body in males either. The beetle can also be confused with the black-footed roller- necked buck ( Musaria affinis ), but in this case the elytra are more conical and the pronotum is only partially orange-red.
Similar species
There are a few similar species, but all of them are rarer:
- Red-headed line buck ( Oberea erythrocephala ) (Cabinet, 1776)
- Honeysuckle Linebuck ( Oberea pupillata ) (Gyllenhal, 1817)
- Hazel line buck ( Oberea linearis ) (Linnaeus, 1768)
- Oberea euphorbiae (Germar, 1813)
- Black-footed roller neck buck ( Musaria affinis ) (Harrer, 1784)
Occurrence
They occur in Europe up to the Arctic Circle and also in Asia in lowlands and the hill country up to subalpine areas. They are quite common on the edges of forests with willows .
Way of life
The larvae live in thin willow branches. When laying eggs, the female gnaws a groove under the egg hole, in which a single egg is laid. This creates growths on the branch, which are the first food for the larvae. These bore into the pith later with a 30 to 40 millimeter long and 3 to 4 millimeter wide passage. They eject the chips through the hole, which it reveals. After one to two years, they pupate in a round chamber just below the surface so that the beetle can easily hatch.
Beetles and larvae eat wood from various types of willow.
