Bug of the Week: Smoke Tree Sharpshooter Revisited

Have you ever encountered a sharpshooter?

eally-close-sharpshooter-undersideYou can tell it is a sharpshooter by the prominent eyes and enlarged, swollen area of the head capsule known as the clypeus. It is yellow with faint stripes in this insect.

The sharpshooter uses its big eyes, too. When something approaches a sharpshooter, it quickly scoots to the other side of the twig or branch. If the potential predator comes even closer, it will leap away with its jumping hind legs.

This is probably a male smoke tree sharpshooter (Homalodisca lacerta) because it lacks the white, waxy patches on the sides of its wings that are found on females (image at BugGuide).

Life cycle:

Unlike some insects, smoke tree sharpshooters are polyphagus, which means they will feed on a number of different plants. The sharpshooter in the top photos is feeding on hollyhock. The single nymph is on Texas yellow bells.

Do sharpshooters occur where you live? Have you ever seen one? What do they feed on where you live?
