Our enchantment with butterflies isn’t surprising. These daytime flyers are easily observed and collectively encompass a rainbow palette of colors punctuated with ornate patterns. However, their close relatives the moths overwhelm butterflies in species diversity and sheer numbers. Most moths are nocturnal and largely out of sight and mind. Nonetheless, they are one of the most important animal groups. Moths are inextricably intertwined with native plants, bats, birds, and the whole of the eastern deciduous forest ecosystem. They play an enormous role in the pollination of native plants and over the eons have spurred the evolution of myriad defensive plant compounds to ward off caterpillar herbivory. In addition, they are often far more interesting than butterflies, both visually and behaviorally. This talk will be a pictorial journey into an intriguing and little known world that unfolds all around us. We can greatly benefit the ecosystem around us by “moth-gardening” in our yards. This program is loosely based on the recent book Gardening for Moths, by McCormac and coauthor Chelsea Gottfried (Ohio University Press).

Instructors: Ellen Lake, PhD

This course bridges the gap between caterpillar ecology and backyard conservation. Dr. Ellen Lake will guide you through fascinating aspects of caterpillar biology and discuss the critical ecosystem services caterpillars provide. You will learn about keystone host plants and best practices for managing a "moth-friendly" landscape. Whether you are a beginner or a seasoned naturalist, you’ll learn how to search for caterpillars, the tools to identify them, and the knowledge to protect and promote them through every stage of their life cycle.

Virtual class ends at 10:30, as the instructor takes the in-person students for a tour of the gardens. All virtual registrants will receive a recording of the class with access to view the class for 30 days after the live session.

Instructors: Matthew Sarver

Often overlooked in favor of their daytime counterparts, moths and their caterpillars are the unsung champions of our local ecosystems. While North America boasts thousands more moth species than butterflies, these nocturnal pollinators are vital links in the food web, converting plant energy into life for countless other animals.

In this course, we delve into the fascinating findings of recent biodiversity surveys at Mt. Cuba Center—including the discovery of 693 species and 25 new state records for Delaware. Participants will learn why moths are the ultimate "specialists" and how their survival depends on specific host-plant requirements.

We will move beyond science and into your own backyard with actionable conservation strategies. From identifying keystone plant species to creating "soft landings" for overwintering pupae, you will discover how to transform your garden into a thriving sanctuary for these diverse and beautiful insects.

    What You’ll Learn:
  • The Power of Pollinators: Understand the critical ecological roles moths play as both pollinators and essential food sources.
  • Local Biodiversity Insights: Explore the data from Mt. Cuba’s iNaturalist project and Sarver Ecological surveys.
  • Native Gardening for Specialists: Identify host plants and keystone species that support specialized caterpillar populations.
  • Moth-Friendly Lighting: Learn how to minimize light pollution using LED, downward-facing, and yellow-wavelength bulbs.
  • Creating Habitats: Master the art of "leaving the leaves" to provide safe overwintering sites in the soil and leaf litter.

Roughly 1/3 of the food we produce ends up in a landfill. Learn how to fight food waste using the black soldier fly! These incredible insects eat spoiled food and produce two amazing outputs: protein-packed larvae to feed animals and frass (insect poop) to supercharge your soil. Compared to traditional methods, composting with black soldier flies offers a much faster decomposition process, boosts beneficial microbes, and can handle a wider variety of waste, including meat and dairy. This class covers their fascinating biology and gives you the resources you need to decide if a black soldier fly setup is right for your home or farm.

Virtual class ends at 2:15, as the instructor takes the in-person students outside for a demonstration. All virtual registrants will receive a recording of the class with access to view the class for 30 days after the live session.

Artificial light at night (ALAN) is one of the fastest-growing forms of environmental change, yet it is underrepresented in conversations about conservation. Take a deep-dive with Astronomer Diane Turnshek and explore how excess nighttime lighting affects the ecosystems that native plants depend upon. You will examine how artificial light can disrupt pollinator behavior, alter insect populations, shift bird migration patterns, affect amphibians and mammals and interfere with predator-prey relationships. Research also shows that light pollution can change flowering times, leaf retention and seasonal growth. This program is for anyone who cares about native plants, ecological gardening and habitat restoration.

Gardening often focuses on sunlight as essential for growth, but darkness is also required for gardens (and gardeners) to truly thrive. In this talk, Leigh Ann Henion will share how spending time with synchronous fireflies motivated her to explore the importance of natural darkness in an age of increasing artificial light. Drawing from her celebrated book, Night Magic: Adventures Among Glowworms, Moon Gardens, and Other Marvels of the Dark, Henion will offer inspiring stories and empowering guidance about how embracing the night can lead to moments of wonder, reduced light pollution, and improved ecological health.  Take part in our flexible online learning offerings.
