Entomology (Study of Bugs)/leaf eating bug or insect.


I have a lemon tree out on deck. Two insects started to eat the leaves. They were in the form of a grass hopper and were light green in color ,about two inches or more in length , and almost the same color as the lemon leaf.What are they?

Dear Mike - Without being able to see an image, I can only guess that they might be a type of katydid (Orthoptera: Tettigoniidae) in the subfamily Phaneropterinae - see for an example. If your specimens do not appear to resemble this example, please try to obtain a clear, close-up image that you could attach to a follow-up question.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
