As a horticulturist, I am often asked to name my favorite plant. After my mind spins from traveling through my past, I am left momentarily speechless. Is my favorite plant the bountiful bunch of cymbidium orchids from Holland or the vivid blue poppies from the Chelsea flower show in London or the pineapple lilies on display at Longwood gardens in Pennsylvania or those gorgeous pink poppies adored by Illinois gardeners?
The most common sawfly that attacks needled evergreens in Illinois is the European pine sawfly, which is present as damaging larvae in the spring. Because this sawfly finishes larval feeding at candle emergence, only second- and third-year needles are consumed. The result is that the emerging needles keep attacked branches alive, even though lower areas of the branch may be stripped of needles.
