They share the same Base Stat Total, as do their respective evolutions, Masquerain and Araquanid. They are available in Pokémon Sun and Moon as well as their upper versions in the same areas, but at different times of day: Surskit during the day, Dewpider during the night. They are said to compete with each other due to similar habitat and diet.
