Potato Leafhopper
 Potato Leafhopper - The potato leafhopper overwinters in the south and is blown north each spring.
The adult is spindle-shaped, about 1/8 inch long and yellowish green in color
with six light spots immediately behind the head. Potato leafhoppers will
usually jump instead of fly when disturbed. The nymphs are smaller versions of
the adults except they do not have wings so they cannot fly. Both the adults and
nymphs can cause damage to the bean plant. They extract sap from the undersides
of leaves causing them to crinkle and curl downward. Extensive feeding can cause
a characteristic triangular yellowing or bronzing of the leaf tip known as "hopperburn."
These plants are usually stunted, have small root systems and have reduced
yields and quality.
