Mark record


The hemlock looper (Lambdina fiscellaria) is a native species found across Canada, and it is considered a serious defoliator. It gets its name from its characteristic walking motion: the larva, which only has legs at either end of its body, moves by thrusting its front legs forward and then dragging the end of its body. The Canadian Forest Service (CFS) has been conducting research on this species for a number of years in order to gain insight into its life cycle, understand its population dynamics, and improve detection and control methods.
