What’s for Dinner?

Most plants get the nutrients they need to grow from soil. Some plants, however, grow
1
in poor soil that doesn’t provide the food the plants need. These plants have to attract
and catch insects to stay alive. Plants that trap and eat insects are called carnivorous,
or meat-eating, plants.
Many plants attract insects with bright colors and pleasant smells, and carnivorous
plants do too. Some carnivorous plants also contain tasty liquids, so insects will come close
and take a drink.
However, scientists have recently discovered something else that attracts insects to some
carnivorous plants. These plants shine with a blue light. The light is ultraviolet, so people
2
can’t see it. The light can’t attract humans, but it is bright and attractive to insects.
Pitcher plants are among the most interesting “ultraviolet” plants. Their leaves form
tubes that hold liquids. The blue light attracts insects to the edge of the plant’s leaves, and
some of them fall in. They try to escape, but the leaves have special hairs that stop them
from climbing out. Soon the insects become a meal for the plant.

1 nutrient: something in food that is necessary for life
2 ultraviolet: a blue color that the human eye cannot see
