Question
bug on red twig dogwood
bug on red twig dogwoo  
I am wondering if you could identify this bug that seems to be killing sections of our red twig dogwood tree? If so how best to control it.

Answer
The picture is a little blurry, but this might be a sharpshooter leafhopper.  They suck sap from woody plants.  Treatments include systemics like Bayer Tree and Shrub insect control or topical sprays approved for trees.  Check with your local nursery.

Expertise

I currently live in San Antonio, TX and have expertise in identifying insects, many types of spiders, and other arthropod critters that infest lawns, ornamentals, structures, trees, pets and livestock. Mites are not a strong point of mine. I'm not a licensed doctor, so I cannot provide medical diagnosis of conditions possibly related to insects or other arthropods. If you've got an interesting photo for me to see, attach it to your question, or let me know and I'll give you my email so the picture will get to me. If you have hosted an insect photo on a website, please include the link so I can go look at it and provide a faster ID for you. You may also join my group page on Facebook and post your picture at www.facebook.com/groups/antmans.hill/.
