Hi. I have been tring to find out some information to help identify what i think is Arcitalitus Dorrieni in my rockery in Cornwall. I am perplexed at the lack of information as it all seems to be about these crustations living in New Zealand! I live in Cornwall and would like to know if the invasion that i have found is anything i need to worry about! Any info would be greatly appreciated.managed to catch one and it soon died in a jar and it did go from what looked like black when alive to a redish brown colour.

Thank you in anticipation......
