Your letter to the bugman:  I found these guys on my prickly pear cactus. They were in the process of spinning silk. No one has been able to ID them. Our local extension suggested prickly pear cactus borer but it doesn’t match other pictures.
How you want your letter signed:  Any help would be appreciated!
