Museum Open House 2017

We hope you all enjoyed our Open House last Saturday. We started the morning in the dark due to a power outage in the Upper Arlington area. Just as we moved specimens and displays outside, the power came back on at 10:30 am and we were able to invite visitors inside.

The auditorium was creeping and crawling with all kinds of arthropods including everyone’s favorite stick insects and scorpions.

Lots of activities awaited all kids and young-at-heart; among others you could plant a seedling, build your own bird feeder, preserve bugs in goo and get your face painted – some artists were at work here.

Herbarium, insects, tetrapods, fishes and mollusc collections had their doors open to give you insights into research in natural history collection and simply show you some of the cool specimens we have.

You could listen to sounds of frogs, cicada, racoons and other animals in the Borror lab of Bioacoustics.

Drawing natural history specimens was a hit, and produced some very nice drawings.

We would like to thank our numerous volunteers without whom this event would not have taken place. They help with set-up, explain displays to visitors and take displays down at the end of the day. THANK YOU.

Let us know what your favorite activity or display was. We hope to see you all again next year!

The Knull Legacy

For the past several weeks, Zach Griebenow (undergraduate student assistant, blogger, majoring in Entomology), and I, with some help from Abbie Zimmer (volunteer, majoring in Art) and Dr. Natalia Molotievskiy, have been reorganizing the beetle holdings of the Triplehorn collection to reflect the changes in the classification of the Coleoptera at the superfamily and family levels (per Bouchard et al., 2011).  This is a laborious process that involves moving (almost) all of the 1,629 (heavy!) wooden drawers containing beetles. On any given day we may move 100-200 drawers in a couple of hours. We are now more than two-thirds of the way done and hope to finish ‘the big switcheroo’ in 2-3 weeks. This re-organization is a big step, and it will greatly facilitate the next phase of the re-curation and digitization of the beetles in the collection.

As we worked, moving drawers in and out of tall metal cabinets, I had a chance to look at the contents of the collection again, not with the critical eye of the professional whose job is to upgrade the curatorial status of it, but with the eye of the student who was seeing it for the first time. This rekindled my appreciation for Joe Knull’s work and his dedication to the collection.

Josef N. Knull

For those unfamiliar with the Triplehorn Insect Collection’s history, Josef Nissley Knull (1891-1975) was hired in 1934 as the full-time curator of insects, and that marks the initiation of a formal entomological collection at Ohio State.

Joe Knull was notoriously meticulous in his care for the collection. He was held up by most entomologists across the country as the extreme example of tidiness and organization. We still have many drawers of beetles that were arranged by him: long series of accurately determined, properly mounted, neatly positioned, and perfectly preserved specimens. There are many stories about Joe’s strict rules in the collection: no smoking, no whistling, no careless people, absolutely no breaking specimens. He allegedly kept a list of all the people who broke specimens. Unfortunately, we have no hard evidence that this list existed, but those who knew him say it would be very much like Joe to do that.

For 28 ½ years Professor Knull devoted his career to the expansion and arrangement of the collection. Each summer of all those years, and those afterward during his retirement, was spent in the field with his wife and fellow entomologist, Dr. Dorothy Johnson Knull. Both were outstanding collectors, and the results of their efforts are reflected in the volume and diversity of material they added to the collection.

Joe was interested in all insects, but he was dedicated to the study of beetles. He published more than 190 papers between 1918 and 1975, particularly on the families Buprestidae, Cerambycidae, Elateridae and Cleridae (Davidson & Bellamy, 2002). The many years of field work with emphasis on beetles, particularly in the Midwestern and  Southwestern states, resulted in a truly outstanding collection of North American Coleoptera.

Professor Josef Knull retired from OSU in January of 1962, but continued collecting and contributing to the OSU collection until the early 1970’s. He died, here in Columbus, on April 24, 1975 at the age of 83. His legacy lives on in every publication generated by the use of the specimens he so carefully collected and preserved, in every visit the collection receives by scientists from the US and abroad, in every specimen image we make available online, in every database query of the 148,154 beetle specimens we have already digitized.

We started re-curating the beetles in 2011. To date, the Carabidae, all 41,466 of them, have been moved to archival quality trays and entirely digitized. Our student assistants are now deep into the digitization of the Tenebrionidae, a whopping 65,150 specimens.  Our volunteers are helping with collection organization. As we continue on with the task of re-curating and digitizing this vast beetle collection (estimated at around 1 million specimens), we keenly feel the responsibility of living up to Joe’s high standards of collection care. I hope he would approve of our work.
