A doctor had indentified the new Spanish invader for the first time in the UK in the spring of last year. Dr. Ian Bedford is head of entomology at the John Innes Centre in Norwich. Well, it is believed that imported salad leaves or plants have to be blamed for brining the slugs in the country.

The size of the slugs becomes four to six inches when fully grown. They also have varied colors ranging from bright orange to a reddish brown. They depend on plant materials for feeding that are shunned by native varieties. They also feed on dead animals and excrement.

They have the ability to acclimatize to dry conditions and multiply in greater numbers than native slugs there.

Researchers are now looking forward to collect as much information as possible about Spanish Slugs with the help of public. This will help them to figure out that to what extent they can be a problem? The SlugWatch website provides all sort of information for both native varieties and the new invaders.

Spanish slugs are already known to have caused crop failures in Scandinavia. Besides, they are suspected to be the cause behind problems with grass fodder crops and oil seed rape last year.
