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.

Not in the garden, but in the dunes about 4 km from
our house A dark head and thorax with three longitudinal stripes. Antennas with black and white rings. A brownish-yellow finely marbled elytra.
Beetle larvae can be found in the stems of many different types of plants. Longhorn beetles prefer thistles.

this beetle live for several years in

Tanbark borer, violet tanbark beetle (Phymatodes testaceus).
Family
Longhorn
beetles or long-horned
beetles (Cerambycidae).
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.

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.
It 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.

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.
Food beetle: Parts of flowers and tree resin.

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.
Europe, North Africa. Recently introduced in eastern North America.

Old house borer
(Hylotrupes bajulus). Family
Longhorn
beetles or long-horned
beetles (Cerambycidae).
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. Photos 6-6-2015.

I want to thank everyone, who has helped me (waarneming.nl)
to identify. In particular, Jan Cuppen and Theodoor Heijerman.
(translated the Dutch longhorn beetles) by Theo Zeegers and Theodoor
Heijerman. Now on internet:
Longhorn
beetles determination based on this book "De Nederlandse boktorren".
It is in Dutch but there are also many photos
of the Dutch species.
