In California we got similar bugs on our Pomegranate tree which my mom called assasin bugs and said they were true bugs. When I was very small my mom took a course in horticulture and had a huge bug collection she had done as a project. I believed her. Was she right as these guys definitely fly? and What are these two? Should I worry about them? The red and black we had in MASSES last year when we bought the house.
