Life Cycle and Behavior
The life cycle of the loosestrife borer is closely tied to its feeding habits. The larvae are characterized as borers, meaning they tunnel into the internal structures of their host plants. Specifically, the larvae bore into the stems and roots of Lysimachia quadrifolia.
Adult moths emerge during the late summer and autumn months. They are typically on the wing from August through October. With a wingspan ranging between 28 mm and 35 mm, they are moderate in size compared to other members of the Noctuidae family.
Geographic Distribution
The loosestrife borer maintains a significant presence across eastern and central North America. Its range is quite broad, stretching from the maritime provinces of New Brunswick in the east down to Georgia in the south. Moving westward, its habitat extends into Illinois, while its northern limits reach into Wisconsin and Ontario, Canada.
