A Huge Thank You with More to Come!

First off thank you so much for taking the time to help transcribe the “Banded Yellow Butterfly” expedition. This expedition was challenging, but you persisted and that shows the amount of care you have for helping natural history collections. Thank you also for providing comments and suggestions. They have been noted and where possible incorporated in to this next expedition for a smoother transcription experience. That being said, let me introduce you to our new expedition “Mixed Bag of Specimens” from the McGuire Center.

The McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of Natural of History is home to one of the largest Lepidoptera collections in the world. Since the opening of the center in 2004, it is has grown rapidly and now has nearly 10 million specimens. The McGuire Center was founded by combining collections from the Allyn Museum (then located in Sarasota, Florida) and the Lepidoptera holdings of the Florida State Collection of Arthropods. While students and staff are constantly contributing to the collection, its growth is primarily due to donations from private collections.

With such big and vast collection, digitizing has taken place on all three floors of collections and with all different species. In this expedition, you will find a mixed bag of specimens to transcribe. All specimens are moths, but there are different species and various layouts. Don’t be discouraged, the information you seek is there.

As you know transcribing this data is extremely important part of the digitization effort. Thank you for taking the time to help! The information that you transcribe is essential to our ongoing research. It enhances data sets and helps answer questions about the history and behavior of these moths and butterflies. We value your contributions to the scientific community, and we thank you for devoting your time and effort to help us complete these butterfly projects.

Tennessee Invaders

There are almost 500 non-native plants that now call Tennessee home. These plants threaten native Tennessee ecosystems. Detection and monitoring, of these species present tremendous challenges to conservation groups. As a first line of defense, organizations such as the Tennessee Invasive Plant Council (TN-IPC) work to list and rank non-native species. Up until recently, organizations such as these have relied heavily on expert opinion and experience to rank non-native species. However, with the onset of metadata technology, the ability to access large amounts of information has transformed the ways in which we might enhance our understanding of the threat non-native species pose across the landscape.

This expedition will assist University of Tennessee at Chattanooga graduate student Courtney Alley (@Calley2012) in collecting data for her thesis research that will utilize this advancement in technology to further our understanding of non-native plant species.  Ultimately, this information will be used to map the locations of these invasive plant species and eventually determine a pattern of spread throughout the state.  With your help, we can use these data to develop more effective detection and monitoring techniques for non-native plants!

Phenology of evening primrose

Oenothera are the evening primroses, or sundrops, and are so named for their tendency to open cheery, long-lasting yellow flowers during the evening. There are about 145 species of evening primrose spread across the New World, where they have long be a cultivated species. One species, Oenothera biennis, is common across eastern and central North America, and has a long history of medicinal use. Much of the plant is edible and the oil for primrose has long been used a traditional medicine.

Evening primrose is pollinated by a special set of bee and moth pollinators with specialized ability to handle its more viscous pollen strands, and its seeds are eaten by birds such as finches. Evening primroses are not related to other primroses in the genus Primula, which are in a different family.  

While diurnal patterns of flower opening and closing is a form of phenology, we are interested here in the seasonal patterns of evening primrose blooming, and especially if climatic changes are impacting evening primrose cycles. We are especially interested in both spring and fall timing since many in this species can have two generation of plants per year.  

We are really excited to launch the Evening Primrose Phenology project as out first truly mobile-friendly Notes from Nature project. We are just looking for help with documenting flower presence, so a simple “yes it has flowers” or “no it doesn’t” suffices.

Its so easy to try one – we hope you do!


Pollinator Plants of Virginia II

Welcome to another edition of the Plants of Virginia expeditions – Pollinator Plants of Virginia II.  In this project, we have assembled a range of species from predominantly animal-pollinated plant families including the Sunflower, Mint, Tomato, Blueberry, Carrot, Coffee and Apple families, all of which provide food for humans, too. Pollinator populations and their overall health have declined in recent decades. While much current research is necessarily focused on the health of non-native, domesticated honey-bees and agricultural productivity, thousands of other invertebrate pollinators such as bumble-bees, small solitary bees, butterflies and moths are in need of help, too. In order for researchers to find these small creatures in the wild to monitor their population sizes or to test them for diseases, they must first locate the food plants that are preferred by each pollinator and wait for their research subjects to appear. Many native pollinator species will consume the pollen or nectar of very few plant species; this very choosy feeding behavior is called oligolecty. It also means that these species can die out if their food plants disappear.  By transcribing these herbarium records, you help us develop very fine scale maps of the plants’ locations and flowering times, which can be used by pollinator researchers to find their quarry.

NfN and the Virginia Master Naturalist Program

We wanted to share this wonderful post about how NfN is being used by the Virginia Master Naturalist program. Master Naturalists can earn volunteer service by working on NfN. The NfN Team is very excited to be part of this partnership!


Another NfN milestone

Half a million? Five hundred thousand? 500K?

Either way it’s an impressive amount of effort from an amazing group of volunteers. Yesterday NfN reached another incredible milestone; 500,000 transcriptions have now been completed since we launched our second version of the platform. Let’s break this down a bit. If the average transcription takes 3 minutes then we have spent 25,000 hours unlocking these important biodiversity resources.

The NfN team is thrilled with the progress that we have been making and as many of you know all our data is slowly making it’s way to open access data portals like SERNEC and iDigBio among others. These data are already being utilized by researchers, conservation organizations and policy makers. We are also very interested in the benefits that our volunteers get from being involved. For example, we often hear from volunteers who tell us how NfN gives them a much-anticipated break from the stresses of their work or how NfN has encouraged them to get involved with one of their local museums. We also hear of volunteers who have taken some of the knowledge they have learned through the expeditions and gotten outside to experience biodiversity in their local area.

It’s been a wonderful journey and we are looking forward to many future milestones!

WeDigFlowering I complete


Enormous thanks to all who participated in the experimental Coreopsis phenology project! I was blown away by your dedication through this new challenge, and I can’t wait to start analyzing the data for trends in flowering and fruiting times. I am also excited to investigate how citizen scientists’ phenological determinations compare to one another and to those of “experts” on the species; perhaps citizen science could be a transformative method for specimen-based studies of phenology!

If you participated in this expedition, we especially want to hear your thoughts on how to improve phenology-related tasks in the future. Please comment or chat with us about what you liked or didn’t like, what helped you most and how you would suggest improving training and the overall experience.

Be on the lookout for new phenology expeditions in the near future, which will likely feature a new segment of plant diversity. Thanks again!
