Native Bees Have Antifreeze!

I spent years worrying Montana's brutal winters killed native bees. Then I learned they produce antifreeze proteins. They NEED cold like native seeds need stratification. Mind-blowing science that'll completely change how you think about fall cleanup." www.secretpollinators.com KEY SOURCES Diapause & cold hardiness in solitary bees Denlinger, D. L. & Lee, R. E.
