Talk Description

 The migratory monarch butterfly—which has captivated generations of people
with its perilous annual journey and its special relationship with
milkweed—was recently declared endangered by the IUCN. As native habitat is
increasingly degraded by climate change, urbanization, herbicides, and
other stressors, the monarch’s dependence on its obligate host plant is
part of what puts the species at risk. Conservation efforts have revealed
that planting milkweed is critical to protect the monarch from extinction
in the face of these threats. However, it is time for Lepidoptera
conservation in the Western US to move beyond this narrow focus on one
species. Hundreds of other Western US butterfly species are in decline,
including some even more at risk of extinction than the monarch. Like the
monarch, each species requires specific native plants to survive. Here, I
analyze interaction data between thousands of butterfly and moth species
and their native host and nectar plants to find the right plants for the
right places to support entire communities of threatened Lepidoptera in
California. I find that relatively few plant species support the majority
of Lepidoptera species, that Lepidoptera species use discrete host and
nectar plants, and that which plants are the most important varies
significantly between California ecoregions and habitat types. I have
integrated these analyses into a web application that helps users find the
best native host and nectar plants to support butterflies and moths
anywhere in California. Future work will incorporate climate change
predictions to guide climate-resilient habitat design for Lepidoptera
conservation.

Bio

Chris is a PhD candidate in Dr. Nicole Rafferty's lab in the Evolution,
Ecology, and Organismal Biology Department at UC Riverside. His research
focuses on how climate change is affecting moths and their interactions
with native plants in California. He has developed a tool called The
Butterfly Net that helps people find the best native host and nectar plants
for butterflies and moths anywhere in California.
