Invertebrate Photographs
Feel free to use these photographs on any of your government, citizen or not-for-profit Web sites. I only ask that you credit this Web site page and acknowledge the name of the photographer in the alt tag. Please email us if you need higher resolution photos or permissions for other purposes. All photographs marked with ESC were taken at USEPA's Region 3 Environmental Science Center at Fort Meade, Maryland. Many thanks to Dave Russell, invertebrate biologist, for arranging the instruction and assistance with the use of the Olympus SZX12 miscroscope with an Olympus model DC330 optical mount. Other photos were taken under contract to EPA by EcoAnalysts, Inc.
