Its a leaf hopper. Not sure what a sponosid is.  They are an insect with piercing mouth parts for sucking plant juices.   
Near NRG Stadium, Houston Texas. USDA zone 9a

Thank you Yorgos.  Do you know any organic pesticide I can use to get rid of them?

I found this in Amazon.  Had anyone tried it before?

If a citrus tree is in a Citrus Greening area such as Florida with active ACP, the chance of the tree getting citrus greening is about 100 percent.  You can spray all you wish but it is still about 100 percent.  All it takes is just one infected psyllid bite.  HLB presently has not cure.  The only treatment to insure that a citrus tree will not be infected would to build a screen around the tree to keep the psyllids from ever landing and feeding on the tree.

For season long control of the ACP psyllid:
For season-long protection, use MoventoŽ at pre-bloom to help control ACP and red scale. At full-bloom, use SivantoŽ Prime to help control ACP and citricola scale and to suppress citrus thrips. Using AdmireŽ Pro at post-bloom promotes further protection against ACP and citricola scale. At fruit growth, Movento helps control ACP, and during harvest, BaythroidŽ XL helps protect against ACP, citrus thrips and katydids.

Hi Millet,

In other word, unless put the tree inside the greenhouse otherwise there is no way to prevent the green disease from infected on the tree.  If it is infected, just destroyed it.

The more knowledge gain, the more worries about the citrus tree

The picture showing adults and nymphs is pretty conclusive of ACP.  The waxy tubules are diagnostic to ACP.

Yes. To date no cure/stop for the spread of hlb. Shame.....perhaps those in research will be the blind hog that finds an acorn........

Looks like a glassy-winged sharpshooter, the vector for a virus that prevents us from growing grapes in the South other than muscadines.

I dissagree. USDA is heavily involved in control of hlb in the door yard citrus community. Hlb was first dected in home citrus trees. Your County Agent will initiate a dertermination as to your trees health. Your University near you is also involved in coordination with USDA and has facilities to test. The treatments for hlb are unproven at this point. The side effects from the treatment are unknown at this point. There is no known "cure" at this point.
