The UK variety [yellow and black] is a beneficial insect as it feeds on rotten wood and pollinates plants, KFF.

But the Asian Longhorn Beetle............



is a different matter.


"Asian Longhorn Beetle (Anoplophora glabripennis)


Asian longhorn beetle (ALB), Anoplophora glabripennis, is a native of China and the Korean peninsula, and poses a serious threat to a wide range of broadleaved trees. It has caused extensive damage to trees in the USA and Italy since being accidentally introduced there in recent years, and there have been outbreaks in several other European Union countries.

The beetles tend to stay close to the site of original infestation in the early stages of an outbreak. However, they can fly more than 2km. Analysis of climate data suggests that most of England and Wales and some warmer coastal areas of Scotland are suitable for beetle establishment, but south-east England and the south coast are at greatest risk.

The lifecycle from egg to beetle is one to two years in parts of Asia, and possibly as long as four years in the UK. Beetles emerge during the summer and will mate and lay eggs, after which they die. Because it is often the resulting emergence holes that are the earliest evidence of an outbreak, it is important to survey and monitor the surrounding area to ensure the adults have not already spread to neighbouring host trees."

But the UK Longhorn Beetle is one to have in the garden.

 

Yep, he's friendly, Linz........so long as you don't keep bugging him!!
