As you will see, we have renewed the images at the top of this page, for which we want to thank Dr. Gary Bauchan (USDA ARS, Electron & Confocal Microscopy Unit, Beltsville, MD) and Dr. Ron Ochoa (USDA ARS, Systematic Entomology Laboratory , Beltsville, MD) for their generosity. Gary and Roy have taken and processed the images and allowed us to share them with everyone who visits this site.
