Butterflies are well known insects that are active by day. They land on flowers to feed so they prefer large, or flat flowers where this is possible. Butterflies pollinate many red flowers with short tubes.
Flowers that are pollinated by moths are often white or pale, and have a strong fragrance. The fragrance is often only released at night to attract nocturnal moths that emerge in the evening or at night to feed. Hawkmoths are very large moths that are active at flowers at dusk. With powerful wing beats they hover before a flower, and use their extra long tongues to access the nectar.
About 4 % of all the plants in Kenya, including Papaya (pawpaw) fruit, and many different African orchids are pollinated by hawkmoths.
