The Seven-Year Caterpillar
Imagine being a kid for seven whole years! Deep in the freezing Arctic, the woolly bear moth takes up to seven years just to grow from a tiny caterpillar into a moth. Because the summer is so short, these fuzzy caterpillars spend almost their whole lives frozen solid like a tiny ice cube! They can survive temperatures as low as -70 °C by making their own natural "antifreeze." Every summer, they wake up for just a few weeks to eat as much as they can before freezing again for another long nap. Learn more!
Wee Ones
The woolly bear moth lives in a very cold place. Is it likely or unlikely that you would find one of these caterpillars in a warm, sunny flower garden in your neighborhood?
Little Kids
A caterpillar egg is only about 1.6 millimetres wide. If we round 1.6 to the nearest whole number, how many millimetres wide is it?
Big Kids
Arctic caterpillars wake up for only 3 weeks every single summer. If there are 7 days in 1 week, how many total days are they active each year?
The Sky's the Limit
A caterpillar can spend 95% of its life frozen. If a caterpillar lives for 100 days, how many days would it be active?
