Phenological shifts as a potential trade-off to high levels of spatial climate change debt
Although distributional shifts have been documented in many butterfly species, Canadian butterflies seem to be spatially lagging behind the pace of climate change. An alternate climate tracking strategy involves shifting phenology to maintain niche requirements; this has not been examined in this group. This study will investigate whether species that are not spatially tracking climate change have advanced their emergence dates instead by looking at dates for first emergence through time. We predict that species that have larger spatial climate debts are emerging earlier in the spring than those who are successful spatial climate trackers.

Assessing the impacts of leaf litter disturbance on overwintering Lepidoptera communities
Little is known about the ecology of overwintering Lepidoptera. However, conservation of this life stage may be vital to protecting threatened populations. One potentially harmful disturbance to overwintering eggs, larvae, and pupa is the seasonal removal or mulching of leaf litter in managed environments. This research examines the impacts of leaf litter removal and mulching on spring-emerging lepidopteran communities and assesses if planting a diverse tree canopy can mitigate the negative effects of litter disturbance. This study will answer questions about an overlooked life stage and provide landowners with conservation strategies to increase the ecological value of their properties.
Joan Mosenthal DeWind was a pioneering member of the Xerces Society. A psychiatric social worker by profession, she was also an avid butterfly gardener and an accomplished amateur lepidopterist. Her contributions of time, organizational expertise, and financial support were essential to the early growth and success of the Xerces Society, and helped found a robust organization that continued to expand in the decades since and become a conservation leader. Joan also had a keen interest in young people, supporting what became the Young Entomologists’ Society. In Joan’s memory, Bill DeWind established this student research endowment fund. The Xerces Society administers two $3,750 awards each year for research into Lepidoptera conservation.
