I think people underestimate how important butterflies are, partly because they aren’t as “efficient” as bees, but efficiency isn’t the whole story. Butterflies pollinate during the day, in different weather conditions, and they cover distances in a way bees sometimes don’t. For example, in my town we had this meadow near the river, full of milkweed and thistles, and every summer the butterflies would be swarming there. A few years back, after some construction and pesticide spraying, their numbers dropped drastically. It was almost eerie—like the silence after birds leave. This is why many ecologists say butterflies are more than just pollinators—they’re environmental signals, little messengers telling us when something is wrong in the system. If anyone wants to dig into the science-y side of it, I found this page pretty useful in explaining the stages of their life cycle and how fragile they actually are:

. What’s scary but also hopeful is that when habitats are restored, butterfly numbers can rebound pretty fast, which shows they’re resilient, but only if we take care of the environment.
