Pine Tube Moth Pupae Overwintering
In eastern North America, the Pine Tube Moth’s primary host is the Eastern White Pine. The moths deposit their eggs on White Pine needles in the spring. The larvae hatch and use silk to form a hollow tube by binding together 5 – 20 needles. They then move up and down their silk-lined tube to feed on the tips of the bound needles. When the tube walls (needles) have been eaten down to one inch, partially developed larvae will abandon their tubes and begin constructing new ones. When feeding and development is completed, larvae pupate inside the needle tubes. There are two generations per year, with second generation pupae spending the winter inside needle tubes and emerging as adult moths in early to mid-April. Pine Tube Moths are not considered a significant pest.
