Beech Scale
A tiny scale insect that feeds on beech bark, creating wounds that allow the Neonectria fungus to enter. Together they cause beech bark disease.
Did You Know?
The scale-fungus complex has killed millions of beech trees across northeastern North America.
Xyelid Pine Bud Sawfly
A tiny sawfly with the characteristic elongated third antennal segment of its ancient family. Adults emerge in early spring to coincide with pine pollen release.
Did You Know?
Xyelid sawflies time their adult emergence precisely to the few weeks when pine male cones are shedding pollen, their larvae's only food source.
