What do all of these elements have in common? Curiously, Smithsonian scientist Harrison Gray Dyar, Jr.. Dyar, Honorary Custodian of Lepidoptera at the United States National Museum (now, National Museum of Natural History) for over 30 years, was a prolific entomologist – studying sawflies, moths, butterflies and mosquitos and publishing his findings. He described hundreds of species and genera and brought new ones to light.
