Found several of these on my Asian pear this morning? Can anyone identify from my less than professional photo? Thanks!
It’s a little hard to see clearly, as it’s at a big of an angle, but it could be a Glassy Winged Sharpshooter nymph to me. A really, really bad, bad guy (vector insect responsible for spreading Pierce’s Disease in grapes as well as Almond & Oleander Leaf Scorch.) The other possible option would be some sort of stink bug nymph, but I don’t think so:

And, let’s hope it’s not the dreaded Brown Marmorated Stink Bug. If you can catch one, and snap a pic of it on a white background, straight on photo, we can better ID it. Also, you can always ask for an ID on bugguide.net, great site for trying to ID bugs:

If it is a Glassy Winged Sharpshooter, you might want to contact UCIPM to see how you can control this really bad pest. I am not sure they’re be after your Asian pears, but if you have plums or pluots, or citrus or oleander in your yard or surrounding yards, then you’re going to have issues.

Doesn’t look like BMSB to me. They’ve started invading Northern California, got my first dozen last year. Hopefully Southern California is faring better…
Ryan, they’re here, but only in certain areas. I have not seen any, thankfully, but we definitely have the GWSS here. It is really what it looks like to me. I had them in my yard several years ago, but now that the 174 acre unmanaged citrus orchard has been taken out adjacent to my property, they have disappeared. Thankfully.
Yup, it looks just like a glassy-winged sharpshooter nymph.
Oh no! You’re right, it looks just like the pictures online. I swished the ones on the Asian pears. Fortunately, they are espaliered so easy to see them. No sign on my citrus or plum but I’ll need to find a long term solution. Thank you all for your help!

Yep, that’s a GWS or some other leafhopper kin. Either way you’ve got some finger smashing to do.

What is the solution for the Glassy Winged Sharpshooter? I used to see one or two here and there but I just noticed about 10 on a small peach tree and 5 or 6 on one of my pluots.
I just heavily pruned my blueberries and found about 20 of these things living on the branches. My blueberries have had a lot of brown leaves and defoliation, could these things be contributing to that?
I finger smash as many as 10 GWS a day on my grapevine in the Summer.
I have found GWS on my satsuma mandarin, when I was trying to figure out what the white residue was on leaves and new fruit (pictured). The UC IPM notes mentions the white excrement, but I’m not sure this is what I’ve got. I’ve hand removed about 6 GWS/day for the past week, I was wondering if the white residue is from the GWS?
