Antonym?
What is the antonym of crepuscular? Is it matinal?
Edited to add: I learned the word in reference to rabbits, and I'd heard the definition as "most active at twilight." I'm hunting for a word for Ingrid, indicating she's active and alert very early in the morning, what many people would refer to as a "lark." Solveig, who is not a morning person, would jokingly refer to herself, in contrast, as crepuscular--although that wouldn't fit if crepuscular means active at twilight and dawn.
