Rose Chafer
The rose chafer (Vis. 1) is a voracious feeder and will
attack almost any plant although blossoms are the preferred.
The insect is most numerous on sandy soils. It overwinters
as a larva and pupates in the spring. The adults emerge
from the soil some time in June. Adult feeding lasts about
a month. Eggs are deposited in grassy areas. The resulting
larvae burrow into the soil and feed on grass roots.
Birds are sometimes killed by eating adult rose chafers
which contain a chemical that affects the heart of small
animals.
Pesticides do not give satisfactory control. The insects
occur in such large numbers that pesticides kill off some
insects but more move in from surrounding areas.
