The gray line is the number of collection events I did each month and correspond to the right axis. You can see a DISTINCT increase in the numbers of specimens I collected starting in September due to the use of two homemade Berlese-Tullgren funnels—the power of passive collecting methods! I collected the most specimens in the fall, with the spring being the second best collecting season. You can see there’s not much of a correlation between the number of specimens collected and how many times I collected each month. Obviously though, I was itching to get out during the spring after being cooped up during the winter, hence the large number of collecting events. https://images.squarespace-cdn.com/content/v1/5c60db79ebfc7f2dae0569c1/fa8b36fb-bcc2-41da-bb97-34ceb5fe27fa/2021graph2.png Blog - The Great Myriapod Extravaganza of 2021 - Make it stand out Unique pedes I collected each month.

By working with museum specimens and new specimens from my own collecting in 20 states, I’m revising the group based on both morphological and molecular data. https://images.squarespace-cdn.com/content/v1/5c60db79ebfc7f2dae0569c1/1551065313749-39OZYLEGNW573H8907J2/Nannaria_IMG_5529-1.jpg Research - Nannaria The genus Nannaria has a large range in eastern North America, but reaches its greatest diversity in Appalachia. Most of its species were previously undescribed, and males have twisted claws of unknown function. By combining intense field collecting with a phylogenetic approach, I described 17 new species in the genus, some of which had been sitting in museum collections for decades. You can read about the new species here. https://images.squarespace-cdn.com/content/v1/5c60db79ebfc7f2dae0569c1/1551065779717-VWYXSDG6MH6D0RET8Y1A/cyanide_gland.jpg Research - Cherry millipede Cyanide Gland Evolution Colorful cyanide-producing millipedes if the family Xystodesmidae are commonly known as cherry millipedes, due to their fruity smell. This surprising scent is a result of a chemical reaction that produces hydrogen cyanide (a poison) and benzaldehyde (the cherry smell). This is a potent anti-predator defense, and these millipedes often mimic co-occurring species. My research focuses on questions of toxicity between millipedes in a mimicry ring and how it evolved across the millipede family tree. https://www.derekhennen.com/publications daily 0.75 2019-02-25 https://images.squarespace-cdn.com/content/v1/5c60db79ebfc7f2dae0569c1/1551066275651-NUB5OL2N5W1JF13P204K/Andrognathus_corticarius_20160520_181918.jpg New Page Andrognathus corticarius, Cope’s Noodle Millipede - An intertwined mating pair with eggs.

D. at Virginia Tech, where I studied the biology of millipedes and described new species of Appalachian millipedes. I graduated from Marietta College with a B.S. in Biology in 2012, and from the University of Arkansas with a M.S. in Entomology in 2015. From 2012-2013, I served as an Americorps VISTA with Friends of Lower Muskingum River in Marietta, Ohio. I have a passion for science communication and exploring the natural heritage of Appalachia. I have led millipede identification workshops in Ohio and Mexico, and in my free time, I enjoy science outreach, hiking, and learning about natural history and botany.
