At my rural household, the most vexatious insect pest has got to be the ubiquitous Japanese beetle. Native to Japan, these pests have infested most of eastern North America, with isolated infestations appearing in some western states. One reason that Japanese beetles are so bad is that they deliver a double-whammy: the larvae (grubs) consume roots and are particularly destructive of turf and pasture grasses while the adults consume leaves and flowers of a wide variety of plants, leaving behind skeletonized versions of the plant parts consumed.

We are often told that every cloud has a silver lining, but when it comes to invasive exotic species, it seems that the proverbial silver lining is vanishingly thin. Invasives like kudzu, Japanese honeysuckle, tree-of-heaven, and oh-so-many others, seem ubiquitous, crowding out native plants and altering all manner of ecological interactions.

Spicebush is a multistemmed deciduous shrub that grows to a height of one to three meters. Young stems are delicate and may be smooth or finely hairy. Leaves are alternate and simple, with an elliptic to obovate blade that tapers at both the base and apex and is bounded by a smooth margin. Examined closely, the margin will reveal a series of fine hairs that project directly out from the leaf edge. In size, leaves are neither remarkably large nor small; they range from one to six inches in length and up to about two and a half inches wide, …
