    If you love pollinators as much as we do, you’re probably aware of the recent population decline of many pollinator species. The fact that 75% of our food is made possible because of pollination from butterflies, bees and other species has made this problem an international priority. Groups like the International Pollinator Initiative are working to highlight the need for public participation and awareness.

    It’s become a local priority as well. On Earth Day of this year, we were happy to host ComEd as the company announced its plan to improve Monarch butterfly breeding areas around its transmission lines. Fidel Marquez, Senior Vice President of Governmental and External Affairs for ComEd, joined us to announce ComEd's plan to increase the mixture of milkweed plants used in its prairie restoration program by more than 30%. Meanwhile, at the Nature Museum, we are continually working to protect and reestablish populations of locally imperiled butterflies. Our efforts are to coordinate the restoration of their native habitat, to propagate imperiled butterflies in our Conservation Lab for the purpose of reintroduction, and to monitor butterfly populations throughout the state with the Illinois Butterfly Monitoring Network citizen science program.

    Two native species we continually work within our Butterfly Restoration Project are the Regal Fritillary (Speyeria idalia), and the Swamp Metalmark (Calephelis muticum). The swamp metalmark, endangered in Illinois, is a rare butterfly that can only be found in wetlands. Its populations are small and intensely local in nature. In contrast, the Regal Fritillary was once common in tallgrass prairies across the country but now is rarely seen east of the Mississippi River. In fact, it is now threatened in Illinois. The Regal Fritillary was recently designated a priority species by the Chicago Wilderness Council with the Peggy Notebaert Nature Museum as the lead partner to coordinate regional efforts to conserve this species. We are also lead partners on two other species, the Monarch Butterfly and the Rusty Patched Bumblebee, and are currently working with Chicago Wilderness developing strategies to protect these species throughout the region.

    We are also doing what we can to help out one of our most effective pollinators, the Honey Bee (Apis mellifera) by hosting a number of beehives on our green roof. You will see our bees' hard at work when you visit our outdoor exhibits Nature Trails and the Woody Wickham Butterfly Garden.

    Wondering how you can work to help pollinators? Here are a few easy ways to start:

    • Plant more native species and pollinator-friendly plants in your yard and garden. Check out this brochure to help you get started.
    • Avoid using pesticides whenever possible. Remove pests by hand and use non-systemic pesticides such as insecticidal soap if necessary.
    • Support the upkeep of our own Woody Wickham Butterfly Garden as it continues to serve as a way-station and food source for Monarchs and other species.
    • Don’t use insecticides on bee swarms. If you notice a swarm on your property, contact a local honey co-op (like the Chicago Honey Co-Op) and a beekeeper will come and remove it from your property.

    We had a mini moment of truth up on the roof this past week -- we took a look into our honey bee hives to see if by chance, some had survived the winter so far. Honestly, there was not much hope. With beekeepers around the country reporting major losses it seemed too much to hope that any of our hives had made it through one of the harshest Chicago winters on record. 

    Honey from the Hive

    Last fall we made the decision to leave all the honey in the hive for our bees, taking none for our traditional honey sale in the museum gift shop. You can buy a little taste of the previous seasons labors in a jar from our gift store. The jars are small, just enough to taste how special our roof top bees are, and not so much that we did not leave them what they need to get through that year, or so we thought. 

    Truthfully, even in the best of years it seems a bit rude and even a little crazy to take honey. Open up a box of bees and take some of their most precious resource, without getting stung…too may times.  We spend the whole summer watching and waiting for this other moment of truth.  How strong is the hive? How much were they able to produce and store? Can they spare some for their caretakers and fans?

    It’s not a new story. People in cultures around the world have been after honey for centuries. There is evidence of humans harvesting honey in cave paintings. Only bees can make it, with their remarkable nectar gathering skills, specialized honey stomach, and a work force to rival whole cities. 

    The manner in which bees are kept, and the ease with which we are able to take a little of the extra honey, has made some real strides over the years. It used to be that you had to completely kill a colony in order to harvest that honey. Now with the use of moveable frames we simply take a few out, process them for honey and return them with much of the comb still in tact.

    The previous year it was a hard winter for many of the honey bees in the area and the ones on the roof of the museum were no exception. Like many of the local beekeepers we were sad to see that despite our efforts, few of our bees made it through the winter in 2012/2013.

    We started fresh this past spring with new colonies. With the help of our local beekeeper Anne, we installed them in June and were happy to see them get as busy as, well, bees. They could be seen around the grounds buzzing around flowers and collecting nectar in the various habit recreations featuring native plantings throughout the growing season.

    So without taking any of the fruits of their labor, we tucked our bees in for the winter of 2013/14.  We added a little extra nutrition to tide them over and some insulation so it would be less drafty. We hoped for a strong start in the spring.

    The good news so far is that when we looked into our hives we found 10 out of 12 with activity. Some look stronger than others and there is still a long way to go until we can say they’re going to make it into the full growing season, but this is far more then we dared hope for.

    We keep hoping for better years for the honey bees and their relatives the native bees. These species are important in helping to provide the pollination that gives us many of our favorite summer flowers and fruits. It’s hard to over estimate the importance of these services in both the natural world and in the cultivated crops we rely on for much of our diet. For now we’ll take this small victory.
