Sharpshooters
are also called Doggers. They are a distinct group of insects belong to
the leafhopper family. About 2.500 species are found in the U.S. and Canada.
Adults are elongated and parallel-sided. They are about 3/8-1/2 inch long
and only about 1/8 inch wide. Their head is elongated, forward-pointing
and rounded in front. Many species are marked or patterned with bright
colors.
Sharpshooters
often sit upside down on the plants and when approached, they will run
sideways around to the opposite side of the stem or leaf that they are
feeding on.
The females deposit
their eggs in plant tissue. The immature look much like the adults except
for size and the absence of wings. Before reaching the adult stage they
go through five immature stages. Some species of sharpshooters have several
generations each year.
They spend the winter
in the egg stage or in some species as adults.
These
pests suck juices from plants. They will feed on many crops, ornamental
plants, trees and weeds. They often excrete a large amount of honeydew
that can result in a condition called sooty mold. Sooty mold is not a
plant disease but it is caused by the black spores of certain fungi feeding
on the honeydew excreted by the sharpshooters.
Some species transmit
certain plant diseases.
Some common species
are; the southern garden leafhopper, the potato leafhopper, the rose leafhopper
and the apple leafhopper.
