The dark-leg short ceiling bracket , small wasps Bock or spruce short ceiling bracket ( Molorchus minor ) is a beetle from the family of longhorn beetles Cerambycidae.
features
The beetles are 6 to 16 millimeters long and are brown-yellow to black in color. They each have an oblique, light spot on their brown wings . The pronotum is narrow and about twice as long as it is wide. He is densely spotted and has long hair. Long, shiny bumps can be seen along the edges, and there is also a hump in the middle of the shield and on both sides. The shortened wings are only slightly longer than the pronotum, gape at the end and end rounded. The fully developed hind wings are folded over the abdomen and about half are visible because of the shortened cover wings. Overall, the males have 11, the females 12 antennae, the females have the antennae about as long as the body, the males significantly longer. Molorchus minor differs from the three similar species in that its third antennae is significantly longer than the first. The legs are long and slender, only the thighs (femora) are spherically thickened.

Occurrence
The animals occur in Europe to the middle of Scandinavia , and in Asia , east to Japan, from low altitudes to the tree line . They are mainly found in clearings and on the edge of coniferous forests . They fly from April / May to July and are common.
Way of life
The adults eat pollen and usually sit on flowers, mostly on hawthorns and umbellate flowers . The larvae live in dead coniferous wood, preferably in dry branches of spruce and pine . But they also feel good in stacks of firewood and wooden fences. They initially live under the bark, their tunnels have a sharp edge there and are filled with drilling dust. Later they live in wood, where they pupate in a doll's cradle. They take one to two years to develop. The adults overwinter in the wood.
