Longhorn
beetles or long-horned
beetles(Cerambycidae)
There are more than 20000 species on the world. In the Netherlands it’s
a lot less. Several larvae are
boring into wood. Several species can cause extensive damage to either
living trees or to wood in buildings (the old house borer Hylotrupes
bajulus ).
The Longhorn
beetlesfeed on flowers, pollen and leaves.
Corymbia
rubraLeptura rubra and Stictoleptura rubra are former
scientific names. They are still used.
Native in
Europe,
North Africa, and Asia. The males have yellowish-brownwing covers. The torax is black. The females (last 3 photographs) havered wing
covers.
The torax is red too and it is larger. Just like most of the longhorn
beetles it has long antennae, The larvae of
this beetle live for several yearsin
dead wood of pine and fir trees, Length :10-20 mm
It looks (colours) and acts like a wasp (movements, restless
with the antennas, etc.)
This beetle I had liberated from a spider web in the scullery.
Size 10 to15 mm.
It feeds on nectar and pollen.
The larva lives in dead wood of foliage trees. Especially on the
beech.
Europe, Asia Minor and Russia
German: Gemeiner, Echter Widderbock French:
Clyte bélier
Grammoptera ruficornis
In May, June, you can find them on flowers. This was on a leaf and it
did not like the camera.
Two weeks later they were everywhere in the garden.
It is matt black in color. Legs and antennae are black with orange.
It's a small longhorn beetle. Length 4.5 to 7 mm
The larvae lives under the bark of decaying branches of different
deciduous trees.
A common species in Europe and Western Asia.
German: Mattschwarze Blütenbock
Pyrrhidium sanguineum
The head is black. The legs and antennae are black. The rest of the body is bright red. The hair is red. The neck shield is uneven.
Beetle larvae are found under the bark of dead branches and trunks. Oak is their
favourite host.
The female is larger than the male. Because the antennas are of equal length,
the antennae of the male look longer. (approximately body length)
April - May
Length 6 to 15 mm
Europe, North Africa, Iran
A tiny beetle. It is common in the Netherlands, but of course you are it easily overlooked. It has a black neck shield with a yellow brown carapace.
The end of the carapace is dark. The front legs are paler than the other
legs. You can just see that it's a hairy beetle. (short hair)
It is mainly found on Prunus species, but also on hawthorn. The larvae live under bark of small
dead branches, of apple, rowan, hawthorn etc. The development takes 1 to 2 years.
Tetrops starkii is very similar. But this beetle is only found in southern Limburg. And
it is very rare.
May-June
Length 3 - 6 mm
Europe, North Africa. Recently introduced in eastern North America

Here
you see the Dasytes on a Trout

wood and are predatory. The beetle emerges in spring.
