                                Longhornbeetles in the garden   

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 beetles feed on flowers, pollen and leaves. They have long antennae.

It looks small in the picture, but otherwise the antennas did not fit in the picture. They are very long. The antennae of the female are about twice the body length, of the male much longer. The elytra are grey. On the pronotum are four yellow-orange bumps. (showing on the pictures) The female has an ovipositor, which protrudes. This is a male. In the photo it sits on the stump of a logged pine. There they are found more often. They feed on bark and needles of pine. The larva of the timber beetle feeds on dead pine wood, which is not rotten. 
April - May and August - September. (Here in March) The adult beetle overwinters.
Length 12 - 20 mm Europe, East-Asia. Photos 13-3-2014.

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.

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.

These longhorn beetles vary greatly in colour. Their elytra are yellow to brown, black, blue or even purple. Thick thighs but thin legs. The pronotum is dark red to yellowish or red.
The larvae live in the wood of dead trees. They are found in the bark, and under the bark in the sapwood. They are in the wood for the fireplace, but not in the wood of houses, because no bark is around it. Mostly oak, but also beech, hornbeam and fruit trees. The beetles live daytime hidden under the bark or in cracks and are active in the evenings.
June - July. Length 8-16 mm
Europe, Asia, the Caucasus, North Africa and now in North America.

This is also a small beetle.
At the tip of each elytron it has a thorn like tooth. The light band on the elytrons is also striking. On the pronotum has two shiny bumps. It looks like the P. hispidulus (rare in the Netherlands). The other family members don't have the thorn like tooth at the end of the elytron.
He lives on various deciduous trees.
Throughout the year. Especially in May and late August.
Length 4 to 6.5 mm The beetle in the picture is about 4 mm.

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

The colour of the elytra of this beetle is black to dark gray. On the elytra it has yellow-brown hairs. On the places without ore with less hairs you see yellowish to reddish brown cross bands and spots. The pronotum has a spine on each side. The antennae are short for a longhorn beetle.
On sandy soils, in the dunes. The larvae develop under the bark of conifers, but also of birch, alder, beech and oak.

Tetrops praeustus, Tetrops praeusta Tetrops praeustus, Tetrops praeusta Tetrops praeustus, Tetrops praeusta. Family Longhorn beetles or long-horned beetles (Cerambycidae).

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

Photographed in Croatia. This is the longhorn beetle, which has caused such a bad name to the longhorn beetles.
The larva is also living in wood of houses and can cause damage. (Especially to roofs) It has a preference for sandy soils and coniferous trees.
A black beetle with a spotty, white-grey hairs on the shields. The pronotum also with white-grey hairs and with some bald, shiny black spots.
Length about 7-21 mm. June August.
Originating in Europe, but having been spread in timber and wood products. Now it almost cosmopolitan and has been found in Southern Africa, Asia, the Americas, Australia.
