A 50-year love affair with hairy caterpillars reveals their squirmy secrets
Western tent caterpillars might not be on your mind every year, but during their peak outbreaks, they’re impossible to ignore—hairy larvae wriggling across roads and swarms of caterpillars climbing houses to form yellow silken cocoons.
They’re certainly on the mind of Dr. Judith Myers, UBC professor, who has spent five decades studying this native moth species and their boom-and-bust population cycles.
In this Q&A, she discusses her journey and findings from a recently published study, including the caterpillars’ surprising resistance to climate change.
To try to solve the puzzle of how the infection persisted and spread over thousands of years in Eurasia, an international team of researchers from the Max Planck Institute of Infection Biology, Harvard University, the University of Arkansas, the Max Planck Institute of Evolutionary Anthropology, and Seoul National University investigated the bones and teeth of Bronze Age livestock at the pastoralist site Arkaim (Russia), a Eurasian Steppe site belonging to the Sintashta-Petrovka culture known for its innovations in cattle, sheep, and horse husbandry. There they identified a 4,000-year-old sheep infected with the same LNBA lineage of Y. pestis that was infecting people at the time.
