As you pour over images of our fascinating CalBug specimens, you may ask yourself how these insects ended up in the museum in the first place. Many of the labels you are transcribing date back to 60-100 years ago, but don’t let that fool you into thinking that museums are places to that just store old specimens. Scientists are still adding to museum collections every day, but how we use specimens now is often in ways that Entomologists 60 years ago could not have imagined.
As a PhD student in the Essig Museum of Entomology, I have had many opportunities to work with insect specimens within a museum. However, this summer I had the chance to go on a month-long expedition in the Appalachian Mountains of North America to collect live insects in the field. My dissertation research involves understanding the diversification and evolution of ground beetles in the genus Scaphinotus. Often referred to as “snail-eaters,” these nocturnal beetles have developed an elongate head and mouthparts, including escargot fork-like jaws and huge sensory palps that allow them to find and feed on snails and slugs. They are flightless and live in predominantly montane habitats. This makes them interesting candidates for studying how body-forms of species change over time, possibly adapting to feeding preferences.
Insect specimens already housed in museums provide a great deal of information about morphology, distribution, seasonality and even behavior, however there is one thing they generally cannot provide- good quality DNA! So today entomologists are frequently heading to the field to collect specimens specifically to extract their DNA. This is why I went on my recent trip to the Appalachians, where I hoped to collect as many as 20 Scaphinotus species to use in my research.
A month-long field excursion requires careful planning and preparation. My trip included visits to 5 states and as many National Forests, where I camped and hiked long-forgotten trails in search of these elusive little beetles. Of course no amount of planning can prevent one from running into a month-long bout of stormy weather! And so it was, my first big trip into the field was vexed by torrential rains, flooding, lightning, thunder, and even a tornado! But in spite of all that heavy weather, rain and mud, I did manage to find a few Scaphinotus (the beetles were possibly as unhappy about the weather as I was!).
I came away from the trip with a far greater understanding and appreciation of what it is like to be in the field collecting specimens first hand. I also chalked up nine additional species whose DNA will contribute to my dissertation research, and will be made available to other scientists worldwide via CalBug and the Essig Museum of Entomology at UC Berkeley.
Wonder where all those specimen images come from? Who are the people working in the museums? What does it look like? Take a behind the scenes look at the Essig Museum and the CalBug project in a new video produced by the California Academy of Sciences.
iDigBio and Zooniverse’s Notes from Nature Project are pleased to invite you to participate in a hackathon to further enable public participation in online transcription of biodiversity specimen labels. The event will occur from December 16-20, 2013, at iDigBio in Gainesville, FL, though you may choose to participate in a subset of the days based upon the schedule. We are especially looking for participation from the most enthusiastic and committed citizen science transcribers! This is a great opportunity to have a direct influence on expanding this tool in the directions you would like to see it go.
The hackathon will produce new functionality and interoperability for Zooniverse’s Notes from Nature and similar transcription tools. There are four areas of development that will be progressively addressed throughout the week.
- Linking images registered to the iDigBio Cloud with transcription tools in order to alleviate storage issues. (Monday)
- Transcription QA/QC and the reconciliation of replicate transcriptions. (Remainder of week)
- Integration of OCR into the transcription workflow. (Remainder of week)
- New UI features and novel incentive approaches for public engagement. (Remainder of week)
There will be opportunities to narrow the focus in each category of activity in a teleconference tentatively scheduled for early in the week of November 25 (and also at the TDWG meeting and the iDigBio Summit, if you are attending either of those events).
If you are interested, please get in touch with Austin Mast (firstname.lastname@example.org) by Wednesday, Nov 1. iDigBio has budgeted some funds to support travel costs.
With best regards,
Austin and Rob Guralnick (UC-Boulder), co-organizers
The Notes from Nature team is proud to report reaching the new milestone of 300,000 transcriptions completed! This has been made possible by the generous and committed efforts of nearly 4,000 citizen scientists from around the globe. We look forward to continuing the project and sharing more biological collections with you in the near future. Thank you citizen scientists!
To continue growing and expanding, we are interested in your feedback. What excites you the most from Notes from Nature so far? How would you like to see it evolve? Leave a comment and let us know!
Since our launch several months ago, the Notes from Nature citizen science community has transcribed 250,000 specimen labels! This is an incredible achievement, and shows promise for where this project can go. We’re indebted to the citizen scientists out there who love this work and have taken it upon themselves to contribute to science in this way.
- Over 3,500 citizen scientists from around the globe participating
- Over 8,800 plant specimens completed (completion requires at least three transcriptions to ensure quality through consensus)
- Over 16,000 insect specimens completed (same requirement as plants)
- Over 25 bird ledger pages completed – these are WAY more time intensive, and were only added days ago (same completion requirement as others)
We’ve learned a lot during this period, and are now in the process of figuring out where to go next, and how to involve bigger crowds of citizen scientists and more interesting collections from around the world. Our recent call for new collections has garnered interest from curators across the US and Europe, and we hope more will be in contact soon. It’s a very exciting time.
Thank you for all your support!
National Moth Week has arrived. Across the country museums and community groups are celebrating the splendor of one of the most diverse herbivore groups on earth. To join in the fun the team at the Essig Museum imaged our collection of hawk moths (family Sphingidae) for the Notes from Nature project – they are sprinkled in with the other CalBug images. Hawk moths (or sphinx moths) range from medium to very large in size, from very cryptic to conspicuously colored, and from day-flying humming bird and bumble bee mimics to night-flying ghosts of the dark forests. Hawk moth caterpillars are known as hornworms, because of the horn-like spike on their hind-end, and include major pests of tomatoes, tobacco, and other crops. See what species live in your state by searching the Butterflies and Moths of North America website.
Moths and butterflies comprise the order Lepidoptera. The name comes from Latin meaning “scale-wings,” referring to the layers of microscopic scales that make up the color patterns on the wings and body (that powder you got on your fingers if you ever touched a butterfly’s wings). These scales can take on many shapes, sizes, and colors depending on their role in camouflage, mating, or protecting eggs. Scale color patterns are very useful in identifying different species of Lepidoptera – most Americans can recognize a monarch butterfly by its black and red pattern. But they are also the focus of very intense research in evolutionary development, biomechanics, biochemistry, and other areas of ecology and evolution. In one of the Hawaiian moths that I study (Cydia) there are special pouches on the male wings that contain pheromone-producing glands and special “sex” scales that help disperse the mate-attracting odors.
As an entomologist I am often asked, “What good are mosquitoes?” Or, “What good are cockroaches?” Or especially because they are the focus of my research, “What good are moths?“ People are most familiar with pests of human enterprise, such as clothes moths (Tinea pellionella and Tineola bisselliella), meal moths (Plodia interpunctella), and various garden pests such as cutworms. But these are a tiny fraction of moth diversity. Also, keep in mind that all animals feed on something and live somewhere. The only thing that makes some of them pests is that they feed on things we rather they didn’t in places we don’t want them to. Imagine if we placed a high value on large piles of manure, then dung beetles would be considered pests as well. But there are also species we think of as beneficial. A great example in the northwestern United States is the cinnabar moth (Tyria jacobaeae) whose caterpillars were imported to feed on tansy ragwort, a pest plant from Eurasia toxic to cattle and other animals. Caterpillars in general keep plants from taking over the world. In turn they are kept in check by their predators, including bats, birds, and parasitic flies and wasps.
Speaking of bats … Did you know that some moths have a tympanum (like our ear drum) that is tuned to the echo location signal of bats? Upon hearing the signal of an approaching bat they begin evasive maneuvers. Some tiger moths even send a signal back to bats saying, “You don’t want to eat me, I don’t taste good.” Recent research suggests that hawk moths produce similar warnings to bats, possibly because they do not taste good (many hornworms feed on toxic plants) or possibly because they have spiky legs that are difficult to swallow.
So what good are moths? Apart from being biologically fascinating, aesthetically pleasing, and behaviorally wondrous, amazing aerial acrobats, important links in food webs and controllers of pest plants, good classroom pets, figures in myths and fables and symbols of change, and important models for ecological and evolutionary research, I guess not much.
