Tiger Beetles: the Often Colorful "Butterflies" of the Beetle World By Bob Nelson
Tiger beetles have that name for a reason - they're fierce predators on almost anything they can subdue. Most species are rarely seen, because as visual hunters they are acutely aware of anything moving in their surroundings and will quickly fly when approached. Maine has some 14 species in this group, including one officially listed as "endangered" and two more listed as "species of special concern."
Bob Nelson earned his B.A. and M.S. degrees in geology, and his Ph.D. in an individually structured program in "Multidisciplinary Quaternary Paleoecology." In this latter, he developed skills in reconstructing past environments from the pollen, seeds, and insect remains found in sediments. He began collecting Coleoptera in 1979, to provide a reference collection to assist in identifying the disarticulated fragments in the sediments. He discovered over a dozen species new to science while collecting in California, Washington State, and Alaska, two of which (Oxypoda nelsoni Lohse and Micropeplus nelsoni Campbell) are now named for him.
After ten years with the U.S. Geological Survey working in northern Alaska, he joined the faculty at Colby College where he taught geology until retiring in 2018. A coauthor on Richard Dearborn's synthesis paper on the Carabidae of Maine, his principal interest is in expanding the knowledge of Maine's ground beetles, and particularly of those taxa found in wetland environments. He was one of the founding members of the M.E.S. in 1997 and was the first VP. He also wrote the Constitution and by-laws, founded the initial web page in 2003 (which ran until Hillary took it over this year), and has been Editor of the newsletter since the beginning of 2007.

Living on the Edge: a Look into the Evolutionary History of the Pitcher Plant Fly by Peter Kann
Переглядів 337 місяців тому
Pitcher plants in the genus Sarracenia are renown for their carnivory, trapping insect prey in their pitfall-like, tubular leaves. Despite their predatory nature, these traps have become home to a community of arthropods that depend on them to complete one or more stages of their life cycles. This diverse community includes representatives from the orders Lepidoptera, Hymenoptera, Araneae, Dipt...
The Ringed Boghaunter: Challenges and Strategies to Detect and Protect a Rare Maine Dragonfly
Переглядів 277 місяців тому
The ringed boghaunter, Williamsonia lintneri, was first discovered in Maine in 1995. The Maine Department of Inland Fisheries and Wildlife has since conducted regular surveys to assess the distribution and status of the species in the state. The ringed boghaunter is listed as a threatened species in Maine. The biology of this species presents survey challenges because of its early and brief fli...
Examining North American Hover Fly Migration Using Stable Deuterium Isotopes (δ2H) by Scott Clem
Переглядів 197 місяців тому
Understanding the seasonal behaviors of North American hover flies (Diptera: Syrphidae) is a severely understudied yet enormously significant area of research. The adult stages of most hover fly species are important pollinators for a variety of crops while many larvae are crucial biological control agents of soft-bodied pests like aphids. Multiple hover fly species around the globe are known t...
How to Shoot Insects...With a Camera by Roger Rittmaster
Переглядів 287 місяців тому
Documenting the diversity of insect life can be done with a killing jar, camera or both. Using artificial intelligence, with programs such as iNaturalist, photographs can lead to the rapid identification of some species. One can also capture the beauty of insects through photographs. Roger Rittmaster, a life-long nature photography enthusiast, will discuss various approaches to insect photograp...
Toxic Nectar? How Plant Chemistry Changes Bee Behavior by Patty Jones
Переглядів 277 місяців тому
Many plants contain toxic compounds in their leaves that help defend them from herbivores. These same toxic compounds also occur in the nectar of the flowers, which has long mystified ecologists, as we view flower nectar predominantly as a reward for flower visitors. There are a number of different hypotheses for why plants would have toxic compounds in their nectar, and I use bumblebees in the...
