Exploring science through art

For the past year, I have been exploring different ways to incorporate science into my photographs. I have always wanted to bridge the gap between science and art so that viewers of all ages can experience a new form of art. I have dreamt of recreating the viewer’s childhood curiosity so that they leave feeling amazed, inspired, and curious once again. Some of my most recent work has been created by making various assortments of slides taken from my own body, such as saliva, zits, hangnails and much more. Each created slide is a self portrait of me on a smaller scale or what I like to call my smaller self. The slides are then viewed and photographed under a microscope. Each image taken can be built up of about 50 to 200 photos that are combined together using Adobe Photoshop.

But where exactly does this all fit in with the Ohio State University’s Triplehorn Insect Collection? In spring 2017 I attended Columbus College of Art and Design’s (CCAD) Biodiversity class. I was lucky to have attended that class when I did because soon after it was dissolved. As part of the class we took a tour of the Triplehorn collection. I was overflowing with excitement! At that time I had only gotten to see a small fraction of what the collection had to offer but it was enough to get me hooked. When it came time to leave I was feeling unfulfilled, the hour we had spent there didn’t seem like it would have been enough. As my classmates and I were collecting our belongings to head out the door someone had mentioned that they also take in interns to help photograph specimens. Hearing that was both extremely exciting and terrifying.

I knew I wanted to help out and be a part of the great things that were happening at the collection but I had also immediately started to doubt myself. I had started to think that I wouldn’t have be a good fit only because I did not have any background experience in entomology. With encouragement from some friends I took the time to look over my completed credits at CCAD. I found out that I had completed all the major photo courses required for me to graduate but I still had extracurricular credit that needed to be completed. Instead of filling my free time with classes that didn’t fit my career path I decided to try and spend it at the collection. With the information I had gathered from my class visit I reached out to the Curator, Dr. Luciana Musetti, who responded to my email almost immediately. Plans were then made to meet up within the week and before I knew it, I was accepted as an intern.

I have already started to work with both macro and microscopic photographs which just so happens to be right up my alley considering this has been where my artwork has been heading. On my second week here I had the chance to photograph a feather-wing beetle, one of the smallest beetles in the world. To the human eye the beetle looks nothing more than the tiniest of speck of dust, but once the beetle was placed under the microscope I could see the silver facets that make up the eyes and that its body was completely covered with hair. But the most amazing part about the beetle was its wings. The wings looked nearly identical to a bird’s feathers, hence the common name, featherwing (or featherwinged) beetles (family Ptiliidae)

This experience has been the perfect opportunity for me since everything I have learned along the way was self-taught and was always a struggle to find the resources that I needed. The techniques they use here to acquire their final image is similar to what I have been doing but more efficient. There are many things I still have to learn that will further help my artwork and future career path within the field of scientific documentation. It’s been under a month since I’ve started interning here and everyone I work with have been extremely helpful and friendly beyond all expectations. Being here is constantly driving me to learn and do more every day. It is so inspiring to be around people with a passion for the world of insects. This has brought many ideas for future projects in mind.

Over the next 4 months or so I’ll be working on various specimen imaging projects, butterflies, beetles, minute parasitoid wasps, and more, and I’ll be trying to learn everything I can along the way. I will also be working on an individual project that I will present at the end of the internship. Keep tuned to my next post here at the Pinning Block.

Researching Pelecinids – Part 2

One of the most useful resources the Triplehorn Insect Collection has to offer is its extensive HOL database, an online taxonomic initiative that documents collected specimens of various insect groups. This database already contains records for over 845 thousand Hymenoptera specimens, and it continues to grow every week through the hard work of countless contributors.

One way to contribute to HOL is to photograph and upload images of collected specimens, further enriching the available data on specific taxa. Prior to the start of my research on pelecinids, there were zero images of the genus Pelecinus available in the database. To remedy this, I had the opportunity to work with Jordan Reynolds, an undergraduate student in Art & Technology who is currently working on specimen photography for the collection. Over the last several weeks, Jordan taught me about the technologies and techniques required for taking high-quality images for the database.



My goal in photographing a selection of the collection’s Pelecinus polyturator specimens is three-fold. First, I will obtain a more in-depth understanding of the external anatomy of these intriguing insects. Second, I can compare the morphologies of males and females of different sizes and localities. Third, I will contribute previously unavailable data to the HOL database.

Photographing collection specimens is not as simple as taking a picture with a camera. Because the specimens are relatively small, and because we require intricate detail in the images, we instead use a method known as focus stacking. With this method, the camera gradually moves along a track and takes multiple images at different distances. The focused areas of each image are then “stacked” together by a computer program so that the entirety of the final image is clear. Because the P. polyturator specimens required a large depth of field, we sometimes had to photograph and stack up to 100 images to create a sufficiently focused final image.

In addition to taking individual specimen images, we also took several comparison images. These provide a quick side-by-side comparison between two different specimens. Some of the images we took compare males and females of similar localities. Other images showcase females of similar localities and their dramatic variance in size.

Of course, no system is perfect, and we faced many challenges along the way. Most of the parasitic wasps that get photographed by the collection are very small in size (no more than a few millimeters long). Therefore, the collection’s microscopic camera that is traditionally used for parasitoid photography is designed to take highly detailed images of very small specimens. P. polyturator females are unusual in that they are very large parasitoids that can exceed 40 mm in length. Because of this, many of the specimens we wanted to photograph could not fit under the microscopic camera. We instead opted to use a DSLR camera, which is used for macrophotography of larger specimens such as beetles and butterflies. Using this nontraditional method of parasitoid photography, we were able to produce high-quality images of the larger specimens by exploiting various imaging techniques.

Another challenge we faced was the handling of the specimens. All mounted insects in a collection must be handled with great care because they are dry and brittle. Pelecinids must be handled with extra caution because their long, string-like antennae and fragile abdomens will break with even the slightest bump.

We ended up with many beautiful images of these wasp specimens. The complete collection of images has been uploaded to HOL and is available on the page dedicated to P. polyturator. I would like to thank Jordan for all of his help with this photography endeavor. Without the countless hours he spent performing behind-the-scenes image processing, the final images could never have turned out so well.

Bumble bees in our garden

 

Every Spring and Summer there are bumble bees in the small garden in front of the Museum of Biological Diversity at Ohio State University.

Bumble bees are fascinating creatures. They play a vital role in our environment, and they are beautiful, too! I am interested in learning more about bumble bees and I am concerned about their future in a rapidly changing world.

For a few years now I’ve been taking photos of the ‘Museum bumble bees’ whenever I have a chance. Sunny, warm days are the best to observe and photograph these hard-working insects. I also keep records of when I took the photos and what kinds of plants where flowering in the garden at the time.

This year I contributed some of my photos and observations to Bumblebee Watch, “a collaborative effort to track and conserve North America’s bumble bees“. This citizen science project is an opportunity for anyone who’s interested in bumble bees to contribute to their conservation by adding precious species distribution information to the site in the form of photos and dots on the map. If everyone who takes a photo of a bumble bee in the USA would submit the image (and where it was taken) to the site, scientists would have a very large amount of important distribution records to work with. The more we know about the bumble bees the better our chances to help them survive.

Bumble Bee Watch (and one of my photos) were featured on the Metro section of the Columbus Dispatch on July 17.

It’s easy to contribute to the site and you can later see your contribution on the Bumble Bee Watch map. My observations and photos are now showing as a little green dot right on 1315 Kinnear Road (the Museum address) in Columbus, Ohio.

Praying mantids have hatched!

Insects are everywhere!  Even in the most urban environment, insects are easy to find.  You just have to keep your eyes open and you will see them. Entomologists are always on the lookout for insects. First, because we admire them, second, because we study them and want to know more about the way they live. Sometimes we bring the insects with us to the lab, sometimes we take photos of them in the wild and leave them be.

Because of that interest, we keep finding cool insects, or insect-related structures. Huayan Chen, an Entomology graduate student in Norman Johnson‘s lab, found this beautiful Chinese praying mantid (Order Mantodea: Family Mantidae: Tenodera sinensis) egg case on the stem of a tall grass on his way home on a cold January day. He brought the egg case back to the lab hoping to find egg parasitoids. However, instead of parasitoids, he was surprised one day by dozens of mantid nymphs. Here are some of the photos he took of the babies as they explored their new world.
