I took a recent vacation to see my grandmother and mother-in-law in Miami. When I came back my garden was a mass jungle of weeds. After I got the majority of the weeds under control I discovered a pest on my wax beans I had never seen before. These bulbous yellow larvae looked like fat catepillars to me. I am now going through the process of eradicating them. Here is a link to information about them in case you are interested. http://creatures.ifas.ufl.edu/veg/bean/mexican_bean_beetle.htm
