Many animals use more than one type of mimicry. This is seen in butterflies, who usually rest with wings folded upwards. They usually have different patterns on the underside of wings. The underside may be cryptic, while the upper side has some warning pattern. Moths, which rest with wings horizontal, may have different patterns on the rear wings. The rear wings are normally covered by the front wings at rest, but can be revealed if the moth is disturbed. This tactic occurs in moths which are active in daytime or twilight. The scarlet tiger moth uses both camouflage and warning colour according to its situation. It is a fine example of how behaviour and mimicry work together.
