Sad Thoughts for a New
Year
Issue #40, January 12th, 2007
Life is always wonderful and bittersweet at the same time. Year-end
is upon us. I appreciate how lucky I am to have a full belly and
garden space to call my own. A life with minimal problems is a blessing
few can boast! Many struggle for food each day. A glance at the
evening news displays a list of kids who die each day. Something
seems wrong in a world where youngsters die untimely deaths.
At the same time, late fall has been glorious with its unusually
warm weather. The green that dwindles in December has not disappeared
because the ground is not yet frozen. It seems more like early April
than the threshold of winter. Since I hate really cold weather,
this has been wonderful.
This warmth has helped spring bulbs build roots and get ready for
spring. Early bulbs are breaking the surface of the soil and forsythia
and witch hazel are blooming in some areas, fooled into thinking
time is not what it is. Even the blue holly at Rock Cottage has
opened its flowers. But the wiser oaks, while their buds are swollen,
still wait for an event several months away.
The inevitable frigid cold of January will soon appear with its
ice and snow. However, I continue to wander through the garden,
silently looking for signs of spring and watching changes on a weekly
basis. The birds don’t seem to mind the lack of cold. The
perennials, anticipating longer, warmer days, are sending forth
fledgling leaves for the New Year. Christmas roses (Helleborus niger)
that were planted beneath the rhododendrons and azaleas are blooming
with their green-white, purple flowers. They will bloom through
March if I understand anything about flowers.
However, I also notice a battle is raging in gardens throughout
the northeast in warmer seasons and is subtly showing itself. It
portends a larger war this coming spring. Oh, life is never easy
and never to be taken for granted!
Though I may never see a battleground with guns and tanks, I wage
a battle with a subtle killer in my garden, the winter moth. You
may have noticed him of late, flittering around windows and nighttime
lights. The warmer late fall weather has provided an entry way for
this pest that is now always there and already attacking.
The winter moth (Operophtera brumata) was introduced to our area
from Europe through Nova Scotia. The pest quickly defoliates deciduous
plant material in the spring. Trees at risk are maples, oaks, cherries,
ash, white elm, apple and blueberry. The moth’s caterpillars,
as they forage, drop from trees into flower and perennial beds where
they eradicate the foliage and kill the plants. There is not much
defense, as there are no natural predators.
Male winter moths have wings that are drab-colored. The hind edge
of their wings are fringed with small hairs and the bottom row of
dark banding near the tip of the wing appears as a series of hash
marks. Adult female winter moths have smaller wings and do not use
them. While flightless, the females are avaricious breeders.
Both male and female moths emerge around Thanksgiving and continue
to emerge well through December whenever milder temperatures prevail.
As with many moths, these are attracted to light. If you see small
moths flittering around windows or lights this time of year, you
probably have something to think about.
Females orient on a vertical silhouette of a surface such as a tree
trunk and race up while emitting a sex pheromone to attract males.
Male winter moths can be seen flying around tree trunks, resting
on the bark and mating with females at this time. They also fly
into homes, and around nighttime lights.
Once they mate, the females continue scurrying up the tree and lay
their eggs. Both males and females die soon after mating and depositing
eggs. Each female lays up to 150 eggs. These egg clusters look like
tiny individual barrels that are tightly packed together. The only
defense against these pests is to spray and kill the caterpillars
in spring. There are no control options for the adult stages of
these moths.
Most people think that gypsy moths are responsible for the defoliation
of spring trees – but it is the winter moth that is the culprit.
Last year was a particularly hard hit. A hoard of moths can defoliate
an entire tree in less than a week.
So, keep an eye out for these pests. If you see them, start saving
your money now to spray this spring!
