[ ♪ Intro] There's been a lot of talk in  recent years about saving the bees.

But when they’re faced with natural disasters, these fuzzy little critters could  be called the ultimate survivors. They’re resilient enough to weather  volcanoes, wildfires, and hurricanes, all thanks to some pretty incredible adaptations  that come in handy when disaster strikes.

Residents of Spain’s La Palma island know  firsthand the devastation a volcano can bring. The Cumbre Vieja volcano erupted in September  2021 and persisted for over three months. Then it was finally declared finished  towards the end of December 2021.

And while this eruption drove people from their  homes, commercial hives of Apis mellifera, also known locally as Canary black  bees, took a different approach. They opted to seal themselves  into their hives for 50 days! They did this with the help of a sticky  substance called propolis, or bee glue.

Propolis is made from water, bee spit,  and plant resin that bees collect. They regularly make and use it in their hives  to seal up cracks, keep the wind and rain out, or as an added layer of security  against potential predators. Or in this case a volcanic eruption!

While the volcano was doing its thing,   bees sealed the hive to keep toxic gasses and ash at bay and the colony alive. While the volcano on La Palma  was still actively erupting, a beekeeper with a farm 600 meters  away from the volcano went to check and see whether anything had  survived the volcano’s wrath. Five of the hives were completely coated in ash, and tens of thousands of bees had sealed   themselves into the hive with the help of that sticky bee glue.

And some apiarists, or beekeepers, described them as less than pleased, but they were still alive. Not only did they have a way to seal up the hive, but they also had all the food they needed  to survive the fifty-day ordeal: honey. Typically bees will eat their  honey stash during winter when there aren’t many  flowers available to harvest.

And the hives near the volcano still had   the entire summer harvest of  honey left inside the hives, because it hadn’t harvested it yet.  So the bees had plenty to snack on. It’s hard to say whether every  single bee survived this ordeal, as it’s tough to count individual bees  in a colony of over ten thousand. But it’s safe to say that most of the  bees in the five hives survived, which is a pretty incredible feat.

Hives closer to the volcano's  lava path weren't so lucky. I mean, there's really not much that  can survive being burned up by lava. But even in the face of fire, bees will at least  make a valiant attempt to stand up to the heat.

For example, beehives located on the roof of the Notre Dame Cathedral survived the 2019 blaze that destroyed a big part of  the famous roof structure. In part, they survived thanks  to their resourcefulness. A common behavior for these critters is that they’ll work together to fan their  hives to keep them from overheating.

This strategy helps them endure  hot summer temperatures, so there’s a possibility they might  have tried this during the fire. Their survival also had to do with  where the hives were located. Like, they were close enough  to get pretty toasty, but they were never in the  direct path of the fire.

But if fires aren’t enough,  there’s also hurricanes which are not a problem for  bees. At least sometimes. As long as their hive doesn’t  go underwater for a long time, that sticky bee glue helps bees keep the worst  of the wind and the rain out of their colony.

The biggest threat to bees in a hurricane is  debris from the storm trashing their hives, or water so high that it floods  the hive drowning the bees. Otherwise, they can seal  their hives up with propolis and ride out the worst of the  storm while surviving on honey. In 2019, when Hurricane Michael  roared across the Florida panhandle, beekeepers didn’t lose everything.

One apiarist even profited from the disaster, selling hurricane honey produced by  his bees that survived the ordeal. So, bees are hard-working  critters who strive to maintain a safe and comfortable living  environment for the entire colony, no matter what nature throws at them. And while they’re certainly resilient   in the face of a disaster, there’s a lot that humans can   do to help make sure that these little survivors   are around for centuries to come.

In the case of commercially kept bees,   apiarists can make sure that  their hives are protected as much as possible should a disaster strike. While volcanic eruptions are   hard to safeguard against, beehives can be secured or transported somewhere   safer in the event of a hurricane or wildfire. And for native bee species, some of   whom are on the brink of extinction, humans can minimize their pesticide usage   and create more pollinator-friendly spaces, to provide habitat for our fuzzy little friends.

It’s the least we can do, as a thanks  for pollinating our crops and, in the case of honey bees,  providing us with a sweet treat. Thank you for watching this episode of SciShow! If you liked learning about all  the great things bees can do, I bet you’ll love our podcast, SciShow Tangents!
