Obscure Scale

Spider Mites
Spider mites (Family Tetranychidae, Order Acari) are not insects; they are closely related to spiders, harvestmen (daddy longlegs), and ticks. Unlike insects, which have six legs and three body parts, spider mites have eight legs and a one-part body. They also lack wings, antennae, and compound eyes. Individual spider mites are almost microscopic, yet when they occur in large numbers, they can cause serious damage. Dozens of species attack shade trees, shrubs, and herbaceous plants.

It attacks spruce, arborvitae, juniper, hemlock, pine, Douglas fir, Fraser fir, and larch, among others.

Recognizing Box Tree Moth in Virginia
Box tree moth (BTM), Cydalima perspectalis (Walker), is a destructive pest of boxwood (Buxus spp.). Native to Asia, BTM spread to Europe in 2006 and into Canada in 2018. BTM was found in New York in 2021, Michigan in 2022, and Ohio in 2023. It has not yet been found in Virginia. BTM feeds on all species of Buxus. Boxwood is a favored ornamental and a staple evergreen shrub cultivated in the US horticultural trade. This fact sheet was developed to help you identify BTM and some of the insects that could be mistaken for it in Virginia.

Arborvitae Leafminer in Virginia
Arborvitae leafminer (Argyresthia thuiella; Lepidoptera: Argyresthiidae) is a small moth that attacks arborvitae (Thuja occidentalis), its cultivars, and sometimes false cypress (Chamaecyparis sp.). Native to North America, it was originally found in the the native host range of arborvitae in the upper Midwest, northeastern US, and adjacent Canada. It has since spread, presumably through the horticultural trade, to other parts of the US, Canada, and Europe.
