Entomology (Study of Bugs)/Spraying bug


I'm in Memphis, TN and I've seen these bugs mainly on my Crape Myrtles.  They appear in spring and I haven't seen one for about two weeks, I see them all times of day.  They are small - maybe 1/4 inch - gray, and almost look like a flounder when viewed from the top.  They constantly squirt liquid out their hind ends.  I haven't seen them fly, mostly they just sit there spraying.  But they will sort of play "hide and seek" with me around a stem (jump/crawl sideways to the other side) if I get too close.


Without at least an image of the insect, and preferably a specimen, I can only say they are some type of leafhopper or planthopper in the order Hemiptera, suborder Auchenorrhyncha.

I'd advise taking intact specimens to a local entomologist at a university, natural history museum, state department of agriculture office, or Cooperative Extension Service (county extension, usually located in the county seat).  He or she would be much more knowledgeable about local insects.

You could also attach an image of the critter(s) with a follow-up question, and I could at least get you into a smaller ballpark of suspects.

Leafhoppers and planthoppers suck sap, but it is not a very nutritious liquid, so they have to consume quite a bit.  It quickly passes through their gut and is excreted as a liquid waste, sometimes forcibly so, as you describe.  Some leafhoppers are even known as "sharpshooters" because of this behavior.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
