Arctic Psyllid
A tiny, winged sap-sucking insect that feeds on willow in Arctic and subarctic regions. Adults are brownish with transparent wings and can jump powerfully using enlarged hind legs. Nymphs produce waxy secretions.
Did You Know?
Psyllids are sometimes called jumping plant lice because they can leap more than 50 times their own body length to escape danger.
Twolined Chestnut Borer
A jewel beetle that attacks stressed oaks and chestnuts in eastern North America. It is named for two pale stripes running along its wing covers.
Did You Know?
Drought-stressed oaks are highly susceptible, and repeated attacks over two to three years can kill large trees.
