2025 Caterpillar-A-Day 365 Calendar - Host Plants Edition REPRINT

Want a calendar that blends beautiful caterpillar images with surprising info and ecological connections!? You're in luck! This year we're reprinting our Host Plants page-a-day calendar, updated for 2025!  Each week, this calendar highlights a plant species or group from eastern North America and some of the various caterpillars that depend on that plant for food! Weekend pages illustrate host plants using vintage natural history illustrations, while weekday pages showcase caterpillars using the Lab's own imagery.  Each page measures 4.5x4in, and has a short, informative paragraph about the featured caterpillar species.  Please pay close attention to your selected amount to avoid paying more than expected: choosing a higher price level will be a donation that goes directly towards supporting the educational, scientific, and artistic efforts of the Lab!  The Caterpillar Lab is a New Hampshire non-profit corporation recognized by the United States Internal Revenue Service as an I.R.C.
