After a recent rainfall, our garden was overrun by strange sluglike creatures.

Question

They are 1″-1 1/2″ long with dark grey segmented bodies, one narrow end and one blunt end and which may or may not have had legs. What are they and are they friend or foe?

Answer 1

I will not be able to know without a photo. Can you include one? This will help me to identify the pest.
