Most butterflies live for only a few days nor weeks. But postman butterflies live for up to 9 months because they feed on pollen as well as nectar. Pollen is rich in nutrients, especially proteins.
Female plants
Female plants Horticulturalist Thomas Ogren believes that pollen
counts have skyrocketed in North America over the last few years
because of the over-use of male plants for landscaping. He suggests
using female plants in the garden to lower pollen counts. However,
he concedes that just going to a garden centre and asking for a
female plant has its problems as the typical nursery won’t
know whether or not they are selling male or female
plants. 17 AUGUST 2000
