Slugs may hibernate during winter but they are active whenever the temperature is above 41 degrees fahrenheit! It was about 43 degrees when we went on our morning walk 1/26/17 so I shouldn’t have been so startled to see an active slug. He/she turned to examine my knife as soon as I put it beside him/her. Please watch where you step when the temperature is over 41 degrees!! You are right to think slugs look like snails without shells. But do they make you think of butter and garlic? They used to live in the ocean, so they still need to keep moist. Reminds me of earthworms…though I didn’t see any earthworms on the road that morning.
