What Are Bumble Bees Attracted To?

Stripes

• According to the scientific paper "Mutations perturbing petal cell shape and anthocyanin synthesis influence bumblebee perception of Antirrhinum majus flower colour ";Adrian G. Dyer, Heather M. Whitney, Sarah E. J. Arnold, Beverley J. Glover and Lars Chittka; 2007, researchers have found that bumble bees are attracted to snapdragons with striped petals. They believe the stripes on the flowers serve to direct the bees into the area of the flower where the most nectar and pollen are to be found. The snapdragons also have closed flowers and the large body of the bumble bee is suitable for opening up the petals so the insect can gain access to the pollen.

Red Flowers

• Flowers containing red anthocyanin pigments were found to be more attractive to bumble bees than white or pink flowers. Anthocyanin pigments give plants and fruits their colors. This means that plants with red flowers or red petals will be more attractive to bumble bees than those with flowers or petals of other colors. A garden full of red flowers should therefore attract many species of the bees.

Wild Flowers

• Wild flowers that produce a lot of pollen and nectar, such as Echieum vulgare, also known as Viper's bugloss or blueweed, are known to attract bumble bees. These flowers are easy to grow and maintain in temperate climates, and tend to produce more pollen and nectar than hybrid, exotic or bedding plants, so are a good choice for gardeners trying to attract bumble bees.

Variety

• There are several different species of bumble bee, each with a different tongue length. A variety of shapes and sizes of flowers will attract different species of bumble bee. Gardens containing flowers with short, single petals suitable for the shorter-tongued species as well as longer, tubular flowers more suitable for species with long tongues should house a large population of bumble bees. The bees are active year-round, so perennials are a good choice for them. Gardens that have a variety of pollen and nectar-rich plants available in each season will be attractive to them.
