Hi Rough,

 

I don't mean to be rude but what is a 'European' Longhorn Beetle ?   And why do you think I should kill it ? 

 

They are little bastards!

They lay eggs under the bark of oak trees.

The larvae eat the tree heartwood for 7-8 years before emerging as the beetle you photographed to breed.

I’ve seen thousands and thousands of dying and dead oaks in France covered in exit holes.

If a single one is found in a container of imported oak, customs will burn the whole shipment.

Kill them on sight!!!!!

Not a joke.

Possibly confused with the Asian Longhorn beetle, but that's black with white markings I think.

 

Is your green longhorn a musk beetle, Aromia moschata?

Hi Paul

 

Good spot. It is indeed a musk beetle.  Lives off (or rather in as a larvae) willow.

Hi Rough

 

As above,  that was a musk beetle.  Yes it is a longhorn but then so are thousands of others (worldwide) - there's over 200 longhorn species here in France.  Many (of their larvae) don't live in trees at all.  The picture before is also a longhorn, the Tanner beetle (aka : the Great British Longhorn beetle). 

 

I think you might be referring to the Grand Capricorne  (Cerambyx cerdo) photo below taken in May.  This is a seriously impressive beetle which we see from time to time and I don't doubt it damages (and occasionally maybe kills) Oaks.  Its numbers are reducing (you be pleased to hear !) and it's now a fully protected species in France.  Their lifecycle is only 3 or 4 years and they don't live in dead trees.  There are plenty of other beetles that will do at least as much damage as these guys but worse than all of them put together, right now our biggest oak killer is drought.
