Approach
slowly and cautiously. Butterflies have good eyesight and are
easily startled by quick movements.
Approach from a low angle. If a butterfly is resting on a flower
or perch at your eye level or above, it is often possible to get
very close.
When one is perched on low vegetation, you should approach from
as close to its level as possible. Butterflies are most wary of
potential predators attacking from above.
Watch out for your shadow. Quick
changes in light may signal danger, such as an approaching
predator, and scare butterflies away.
Take advantage of opportunities. Butterflies are easier to
observe when feeding at flowers or laying eggs.
