Proper lighting is essential for a built-in indoor butterfly and insect sanctuary. Butterflies are attracted to bright, natural light, so ensure that your sanctuary has ample access to sunlight. If natural light is limited, consider installing full-spectrum artificial lights that mimic the sun's rays. Avoid using harsh or ultraviolet lights, as they can be harmful to butterflies and insects. Maintaining proper lighting will create an ideal environment for these creatures to thrive.
