Dear colleagues,

I would like to know how to categorize abundance of the insect.
What is beetle like Rosalia alpina? Rare or Endangered?
Is there any link between category like:
Very common - Common - Very abundant - Abundant - Rare - Very rare -
Sporadic
and category like:
Common - Vulnerable  - Threatened - Endangered - Critically Endangered???

Is there any paper, publication dealing with this issues?

Thank you very much for your help.
Keep care and be of good cheer.

Regards
