Flower color is often purple or brownish, resembling carrion Many beetle and fly flowers produce carrion odors and attract carrion insects who think the flower is a place to lay eggs. While the insect wanders across the surface of the flower looking for a suitable site, it picks up pollen, which it then distributes to another flower when it tries again. Some beetles feed on flowers or specialized food bodies produced by flowers. Such flowers often have inferior ovaries. Bees, wasps and bee flies (bee mimics) The most famous pollinators are bees. Bees and their flowers have been studied

Bees have body hairs and leg (and other) appendages specialized for collecting pollen and nectar, which is taken back to the hive to feed larvae. Most bees must land on the flower to obtain nectar and pollen. It is common for flowers to have designs that guide the bee to the appropriate location and platforms for the bee to land on . These flower patterns are called honey guides and landing platforms. Moreover, some patterns are not visible to humans but are visible in UV light, which many insects can see. Bees do not see red, however, so red flowers are rarely pollinated by bees. Blue and yellow flowers are the most common bee flower colors...
