I am new to veggie gardening and do NOT want to use any chemicals. I am currently using ladybugs, killing by hand, yellow sticky paper and water hose to control whiteflies. All 3 pictures are leaves of my metki white cucumbers. Does anyone know what is about to hatch out of this pod? I have opposing opinions about the greenish, golden fly. One experienced gardener told me he wasn't sure what it is, but it is not harmful. Another person from a local nursery thought is was a leaf miner, but he didn't seem too sharp. Is the last picture a HUGE whitefly or do I have another type of insect?
