A Mother’s Love: The Race to Provide

A Mother’s Love: The Race to Provide

Metallic Green Sweat Bee

A speck of sunlight warmed the face of a mother, causing her to wake and stand up. She took a few steps toward the sunlight, letting it warm her cold legs in her tunnel. Looking back at the wall of her nursery, she knew she had limited time to finish her work. Behind that wall was a row of rooms, one for each of her eggs. Each nursery room was provisioned with pollen and walled off from the others, providing a safe place to hatch, overwinter, and hopefully emerge next year. Her antennae started twitching excitedly. She tried beating her wings; they buzzed. She was warm and ready for another day’s work.

She cautiously peeped over the lip of her nest entrance. She was a metallic green sweat bee, and just last week she watched as a parasitic bee invaded one of her neighbors’ nests, ending the hope of a future generation from that mother. To keep all her efforts from being in vain, she had to leave and enter her nest in complete secrecy. She scanned the area around her, checking for someone perched on the tops of rocks or hidden in the shaded spaces between grass stems. So far so clear. She stepped out of her nest, allowing the sun to warm her entire body. Looking around once more, and seeing no sign of threat, she zipped off to start her chores.

Gathering pollen was her favorite chore. She had already started a new nursery cell; all there was left to do was to lay an egg and provide a provision of food. Using the sun as a compass, she navigated to a large patch of gold that she had seen yesterday. The yellow rays of one unoccupied flower caught her eye, and she flew into its center, landing on a blanket of brown bristles topped with yellow tufts of pollen. The buzzing of other insects at neighboring flowers reverberated in the air around her, and caused the flower to tremble even more in the breeze. The air was slowly growing cooler each day. It was taking her longer and longer to warm up enough to fly in the mornings. The frantic buzzing of other insects confirmed a sense of fear she didn’t quite understand. She sensed that she must hurry.

Native Sunflower

Thinking of her young ones back at the nest, she worked as quickly as possible, picking up pollen and snatching a mouthful for herself every now and then. As she moved across the flower, she let her body brush against as much pollen as possible. She paused periodically to comb this pollen from her abdomen, head, and feet to tuck it onto her back legs where she had thicker, hooked hair that was much better at holding pollen in place. The sun shone on, warming her even more. Through the race to gather and provide for her family, it was nice to be out in the sun and surrounded by velvety gold rays. The bristled brown underneath felt good on her feet and belly. Once she was through gathering here, she remembered a bright purple area that had looked promising.

Looking for her Nest

After a while, the little sweat bee had as much pollen as she could carry. Pushing off the sunflower, she flew back toward her nest, only pausing once for a breath on a stand of purple flowers. Back on the ground, she felt around with her antennae until she found her own nest entrance. She peered inside her dark nest. All was quiet, just how she left it. She glanced behind her. No one had seen her; her family was safe.

As she pulled pollen off her legs and rolled it into a loaf, she had a sense that this may be the last nest she would finish. She felt much more tired compared to a few weeks ago. She was particularly proud of this nest: it was in a well-hidden location, its walls were smooth, and she had a good mix of pollen from different flowers within each loaf she had made for her children. Although she would never get to meet them, she was glad they would have all the nutrition they would need to start a successful life. She hoped they would find the yellow and purple flower patches. She grew more tired. Maybe one more pollen collecting trip before she turned in for the day.

Missing Monarchs, What it Means, Why it Matters, and How to Help.

Missing Monarchs, What it Means, Why it Matters, and How to Help.

It seems to be a yearly event nowadays, that we wait with bated breath for the release of the year’s final monarch count from Mexico, where they spend the winter.  Similarly, each year, we’re let down with the news that the population has fallen again.  This same thing has happened this year, with MonarchWatch’s yearly report from the field.  Yet again we’ve seen a decline, with the total area covered by monarchs in their overwintering site falling 26% compared to last year, now only covering 2.1 hectares (5.2 acres).  For a comparison, the indicator of a healthy Monarch population is an overwintering area of 6 hectares (14.8 acres).  So what’s going on here, and more importantly, what does it mean?

It’s time for my controversial but true statement, monarchs really aren’t good pollinators. There, I said it! They don’t contribute very much to fruit or seed production, and they certainly don’t help with our food security.  So what’s the deal?  Why are we spending our time and energy monitoring and reporting on them?  Well, there are a lot of reasons why protecting them matters. For example, if you felt uncomfortable, angry, or saddened by any of my previous statements in these last 2 paragraphs, then that’s a fantastic reason on its own to protect them.  

Monarchs have a special place in the culture of Iowa, the Midwest, and North America as a whole.  Most people that I talk to about the plight of the monarchs reminisce about seeing them delicately flying around in the summer.  Many more, myself included, have fond memories of raising and releasing Monarchs as part of countless elementary school science classes.  For many people, monarchs were a great introduction to the wonders of nature, highlighting how creatures can grow and change through time in order to adapt to their surroundings.  Monarchs also teach us about migration and animal movement, how creatures overcome great odds, and large distances all for the sake of the next generation, who in turn will repeat the cycle.

Outside of nostalgia, metaphor, and symbolism, monarchs have an important role in conservation as what’s called an indicator species.  Because of their size, recognizability, and large range, tracking a trend in the population of monarchs is far easier than, say, a small, camouflaged, yet more-efficient pollinator.  If we know that both of these creatures have similar habitat and dietary needs, it is in our best interest, time and energy-wise to focus on the big, orange, easy-to-track species.  By providing the good habitat, food, and space for a monarch, we can expect other pollinators to use those resources in a similar way.  Similarly, if we see declines in monarch numbers, we can use that data to assume that other species of pollinators are also declining for similar reasons.

It’s in our best interest to protect monarchs, because by extension, we’ll be protecting pollinators as a whole.  Now you may be wondering how you can help monarchs and pollinators, what things you can do to help reverse these declines?  The good news is that no matter where you live, or how much land you have, you can help your local pollinators.  All it takes to start is a few seeds, easy enough right?  

Well, no…you need to make sure you plant the right seeds for the job.  Monarchs and pollinators evolved right alongside our native plants, so those are the plants to grow that will cover all of their nutritional needs.  If you aren’t able to access native plants, or don’t have the space for them, non-native nectar plants like lavender, mint, and clover are all good options (just make sure that they don’t spread outside of a designated area!)  Also plant “host plants.”  These are specific species of plants that caterpillars will eat to prepare them for becoming butterflies.  The host plants for monarchs are famously milkweeds, but every other butterfly has their own version of this.  Finally, your plants should bloom throughout the season, with species blooming continuously between May and October.  This way, you’ll know that you’re providing a source of flood for hungry pollinators at all times.

Monarchs may not be the best at pollinating, but they are an important symbol.  They symbolize migration, change, and the cycle of nature.  They also symbolize pollinators as a whole, illustrating their needs, their declines, and their need for protection.  Again, by protecting monarchs, providing them with spaces for them to grow, thrive, and eventually venture out from, we’ll be able to protect all of our pollinators.
