To many to just list off..LOL. Thamnophis are a generally known diurnal species. Some snakes are generally diurnal, but become crepescular and nocturnal as the season gets warmer. Some crepescular and nocturnal species start off and end their years by being diurnal...it all depends. Nothing is truly set in stone for the average snake.
Honestly, no better way of finding out than researching. Natural history reports for any given species are good for this, so are basic informational sources.
