Fairfax Master Naturalist CaterpillarsCount! Project

Don Coram

CaterpillarsCount! (Citizen Science Service Code C254) is part of a multi-year, multi-site National Science Foundation-funded study to determine whether seasonal activity of plants, insects, and birds are all responding in the same way to climate change. The lead universities for the study are University of North Carolina, Georgetown University, and University of Connecticut.  Figure 1 maps the 73 sites around the Eastern U.S. that collected data in 2018. 

The paper that was the impetus for the project is Increasing phenological asynchrony between spring green-up and arrival of migratory birds”, which appeared in Nature’s Scientific Reports, Vol. 7, in 2017. Phenology is a branch of science dealing with the relations between climate and periodic biological phenomena (such as bird migration or plant flowering). At each site, volunteer citizen scientists count caterpillars and other arthropods on a specific collection of 50 leaves on each of 10 trees during the growing season (May-August). (50 is an arbitrary number intended to be a balance between getting enough data and not creating an overwhelming data collection chore.) These counts will be repeated over several years to look for trends. With 73 sites, there is no way this data could be collected without citizen scientists, hence the participation of naturalists like us.  Researchers at the universities analyze the data.  

For the Fairfax County site, the selected trees are in the Walker Nature Center (WNC) in Reston. WNC Director, Katie Shaw, is the site manager. I am the lead data collector, assisted by two other FMN members, Kim Schauer and Claudia Thompson-Deahl. Elise Larsen of Georgetown University has been our point of contact with the national CaterpillarsCount! project.  

In 2018, we conducted 140 surveys on 14 different dates, observing a total of 500 arthropods, including 13 caterpillars, which were present on 9.29% of surveys. (A “survey” observes the 50 leaves of one tree.) Nationally, the top 10 sites had caterpillars present in average of 5.32% of surveys, so our site looks good from this perspective.  

One of the prettiest caterpillars we found was the American dagger moth caterpillar, Acronicta americana, shown in Figure 2. We also observed fall webworm moth caterpillars, geometer moth caterpillars, and others that we could not identify.  Among the other arthropods we observed were debris-carrying lacewing larvae, daddy longlegs, beetle larvae, and sylvan jumping spiders.  

Because caterpillars are a major source of food for nestlings of migratory birds, we are especially interested in the timing of caterpillar availability. Caterpillar phenology  (e.g., lifecycle events) at the WNC site is shown in the Figure 3. Caterpillar occurrence peaked at 36.36% of surveys on August 19. Note that August 19 is late to provide a food source for nestlings. My conjecture for this lateness is that the insects usually responsible for caterpillars in the spring are becoming rarer (along with most flying insects; see More than 75 Percent Decline over 27 Years in Total Flying Insect Biomass in Protected Areas) and fall insects do not suffer as much predation by birds. No conclusions can be suggested yet about the effect of climate  change, since the sturdy will need to go on for several years to obtain comparative data.  

It is interesting that the “caterpillar” we observed most often is not a caterpillar at all. By definition, caterpillars are in the Order Lepidoptera (butterflies and moths), whereas the most observed larvae were dogwood sawfly larvae, Macremphytus testaceus, in the Order  Hymenoptera (bees, wasps and ants). Two of these larvae are shown in Figure 4. The larvae were so numerous that they defoliated the tree, a Red Osier dogwood.  

One benefit in participating in CaterpillarsCount! is learning to identify all sorts of arthropods. There is an online training course and field guide for this purpose. As a novice entomologist, I found both the opportunity and guidance valuable. 

One unexpected benefit is the opportunity to observe nature surrounding the survey sites in a leisurely way, closely, and repeatedly. I noticed animals that I missed on other visits to WNC, such as tadpoles growing legs, a Northern water snake sunning on the rocks, a grey catbird taking a bath, an American rubyspot damselfly, and a violet dancer damselfly.  

The project could use additional volunteers this year and in the future. New volunteers could establish a new survey site or help with the WNC site. Training and support are provided.  

Please join me at the Walker Nature Center on April 23 for a discussion of the project. Elise Larsen will present with me. The talk counts for continuing education credits.

Frying Pan Farm Park Pollinator Garden: Community Partnerships in Action

Kim Scudera

In 2011, Frying Pan Park did not have a pollinator garden.

By October 2012, they did, and Fairfax Master Naturalist volunteers are the reason. Here’s the story.

Frying Pan has a long history, and hosts thousands of visitors each year, many of whom are the future stewards of our environment: young children. My own children had participated for years in summer camps at Frying Pan, learning about farm life and farm animals, making butter, playing outdoors.

In July of 2012, Ashley Stanton, then service project chair for FMN, put out a call for the development of a pollinator garden, as a “thank you” to Frying Pan for hosting our annual meeting.

Sarah Mayhew, FMN Class of ‘07, pulled together a team of people from Frying Pan Park, the Fairfax chapter of the Virginia Master Naturalist program, and representatives of the Virginia Native Plant Society (Potowmack Chapter) and Earth Sangha. Without her strong leadership, this project could not have happened. Carmen Bishop, FMN ’07, served tirelessly as liaison to the park.  

A site was chosen near the historic farmhouse: the location wraps around the south and east sides of the park’s Dairy House, where a neglected garden, created by a Girl Scout troop about ten years back, was in need of a major retrofit.

With lots of input from Carmen, Sarah, Cindy Morrow, Amol Kaikini, Terrence Liercke, Alan Ford, and Lisa Bright from Earth Sangha, I designed the pollinator garden in August 2012. By September, garden preparation was complete, and plants were donated by many FMN’ers, and by VNPS Potowmack and Earth Sangha.  

Why did VNPS and Earth Sangha choose to become involved? Expanding our understanding of the value of native plants, and putting those plants into the hands of Virginia homeowners, schools, and businesses, are key elements of the missions of these two organizations. Personal connections matter, too: for example, then-VNPS Potowmack President Alan Ford is a Fairfax Master Naturalist, and these personal connections brought volunteers and donations of plants to the garden.

Two planting days were all it took to get the garden established. The garden includes many plants important to bees, butterflies, and other pollinating insects, including goldenrods, bee balm, and milkweed.

It’s one thing to get a garden started; the real challenge is keeping it going. Since 2012, I have donated over 275 hours of time caring for this garden, with help from the park (big thanks to Patrick McNamara and Marge Landis) and from FMN members. Cindy Morrow and Cynde Sears have been exceptionally helpful. 

The scope has expanded from the original Dairy House planting to maintenance and expansion of the herb garden around the Smoke House adjacent to the Dairy House.  

The herb garden was already a real magnet for pollinators of all sorts:  bees, butterflies, flies, wasps, and more. It was already home to a substantial stand of our native mountain mint. Adding more native plants with culinary uses was an obvious addition to our mission at Frying Pan, and Girl Scout Rachel O, along with her sponsor Kay Fowler, added many of these plants in 2016.

The garden has filled in well since it was first planted:

Garden right after planting

Garden as of summer 2017

These photographs document the growth that made possible a dramatic increase in beneficial insects and their larvae in the garden: butterflies and moths (e.g., skippers, fritillaries, monarchs, cecropia moths) have been most prevalent. 

The garden has not only attracted more flying visitors—it has encouraged a considerable increase in two-legged traffic as well. The pollinator garden has hosted Brownie and Scout troops, summer campers and school groups for presentations on the value of pollinators and the plants that host them, and a steady stream of park visitors now have an interesting destination right next to the historic farmhouse, and en route to the chickens. 

In addition, at the park’s major events, FMN has hosted information tables which reached dozens of park visitors.  These tables were staffed by Marilyn Schroeder, Joe Gorney, Valerie Lamont, Barbara Whayne, and me.

Tending the garden—which I have done since inception—is a labor of love. I plan to not only keep it going, but to make it a service project of choice for the chapter (look for S109 if you’re a member). There’s still so much to do: more edging, pruning, planting, signage, weeding, formal certification by Audubon at Home, National Wildlife Federation, Xerces… And as my mother and grandmother always said, “Many hands make light work!”

Butterflies and Blossoms, or Larval Host Plants and the Lepidoptera that Eat Them
Thursday, February 14, 7:30 pm – 9:00 pm
Green Spring Gardens, 4603 Green Spring Road, Alexandria VA

No reservations are necessary for this talk.
Virginia Native Plant Society programs are free and open to the public.

Margaret Chatham will discuss butterflies, caterpillars, and larval host plants.

Beautiful butterflies and lovely blossoms are all the result of trying to make a living. The plants need someone to pollinate them, but at the same time need to limit the number of caterpillars and other insects that can eat them. The butterflies and caterpillars need to avoid being eaten long enough to lay eggs for the next generation. Learn which natives to plant to nurture more than just monarchs.

2010 was a good year for butterfly photographs in our area. Margaret Chatham took a lot of pictures that year. Then she wanted to know who they were and what they ate. No year since has offered her quite as many butterflies, but every season brings something new, so now she wants to share them.

Margaret is a devoted Fraser Preserve Volunteer Visitation Committee Member who removes invasive barberry shrubs in winter and wavyleaf grass in summer and knows the preserve intimately. She is also editor of the VNPS Potowmack News newsletter, a volunteer at the VNPS propagation beds at Green Spring Gardens in Alexandria, and an Arlington Regional Master Naturalist.

Mark Your Ballot: Goldenrods or Asters?

0.jpgWhile humans are bustling about on election campaigns, the rest of the world’s citizens are frenetically preparing for winter. Bees, butterflies, and other pollinators seek out the last of the flowering plants. In the Mid-Atlantic area, goldenrods and asters provide that critical food source (just as red maples fill that need at the other end of the growing season, when bees start to emerge in the spring before anything else is blooming.)

If you pause for a minute in front of blooming goldenrods and asters, you will be astonished at the number of bees foraging for nectar and pollen, including many of the hundreds of species of native bees and the non-native honeybees. If the sun is shining and the temperature is high enough, you will also be treated to the sight of butterflies and skippers flitting from flower to flower. Look very closely at the goldenrod flowers and you will find a whole world of tiny beetles and other creatures hiding between the blossoms.

There are many species of goldenrods and asters, all very easy to grow. They come in different sizes, and asters come in different colors. Some self-seed exuberantly, some are more contained. You can find out the details by consulting the Plant NOVA Natives online search app. Late autumn is not too late to plant, as the roots will continue to grow even as the tops die back.

Cast your ballot on our Bloom Time Table page by clicking here to choose your favorite. Or vote instead on the Plant NOVA Natives Facebook page. Polls close at 7 pm on November 6, of course! We know who the insects are voting for: there is nothing elective for them about native plants, upon which they are completely dependent. To help you choose, check out the “campaign ads” on this short video.

Caterpillars Count! Join new citizen science project

Caterpillars Count! is a citizen science project sponsored by the National Science Foundation for measuring the seasonal variation and abundance of arthropods like caterpillars, beetles, and spiders found on the foliage of trees and shrubs. Arthropods are an important food source for birds and other wildlife.

Climate change is affecting the timing of spring leaf out, insect activity, and bird migration and breeding. But are the plants, insects and birds all responding to the same degree? If either insects or birds are not keeping up with the shifts of the other organisms that they depend on, then further climate change may have negative consequences for their populations.

Caterpillars Count is part of a multi-university study of phenological mismatch across three trophic levels in eastern North America. The lead universities are University of North Carolina, Georgetown University, and University of Connecticut, with co-investigators from University of Florida, Institute for Bird Populations, Penn State, Evergreen State College, and Ontario Forest Research Institute.

Participants will monitor a site at the Walker Nature Center in Reston for Georgetown University. We will examine 50 leaves on each of 10 trees weeklyor bi-weekly thoughout the spring and summer.  We will count and classify the arthropods we observe. Each monitoring session will take about one hour. There will be approximately 16 monitoring sessions. Volunteeers are not required to participate in every session and the timing is up to the volunteers who are participating. Volunteers must sign-up in advance for training and schedule coordination.

This project is eligible for credit for master naturalists under code C-254.

Attend Butterfly Identification Workshop, with Dr. Leslie Ries, 25 June

The sight of butterflies fluttering around on a warm day is one of the most iconic signs of summer. These beautiful insects usually only live for a few weeks as adults, but they make quite an impression while they are in their full glory. There is a large variety of butterfly species in our area and we are going to census them on June 30 during the Audubon Society of Northern Virginia Butterfly Count in and around our Occoquan Bay Count Ciricle.  

In preparation, Dr. Leslie Ries will be teaching a butterfly workshop focusing on identifying butterflies in Northern Virginia. The classroom portion of the workshop is FREE and will be on Monday, 25 June.

The field trip portion will be in conjunction with the count on June 30.
