Pest identification and confirmation—Treehoppers
Two common treehopper species in landscapes
The oak treehopper is common
in the spring throughout the United States on the lower
branches of deciduous
and live oaks and occasionally on birch, chestnut,
or other broadleaf trees. Adults are olive green
to bronze with reddish bands and their surface is covered
with tiny pits. They often scurry to the opposite
of the twig or leaf when approached. Females usually
remain with their eggs and the nymphs after they
emerge. The nymphs are black with yellow and red markings.
The spring generation is colorful and usually gregarious;
individuals typically aggregate in rows on twigs.
The buffalo treehopper is common in landscapes throughout
the United States. Its hosts include ash, elm, fruit trees,
hawthorn, locust, poplar, and many herbaceous plants. Adults
are bright green or yellowish with a yellowish underside.
Nymphs are green with prominent spines on the back.
