June is National Pollinator Month!

We are *buzzing* with exciting news! Mayor John Haila recently proclaimed National Pollinator Week in Ames, starting on Monday, June 19. Additionally, Haila announced a plan to make Ames a more pollinator-friendly city! To our knowledge, Ames is the first city in the United States to create its own 10-year plan, tailor-made for Ames residents and Iowa-native pollinators. Prairie Rivers of Iowa partnered with the City of Ames Public Works Department to organize a Pollinator Task Force, comprised of Ames residents, who came together to write the City of Ames Pollinator-Friendly Community Plan. Prairie Rivers and the City of Ames are now calling on even more residents to get involved in implementing this 10-year plan. You may be asking: ‘Why proclaim a national pollinator week, and why should we have a plan concerning pollinators for Ames?’. Because supporting pollinators is supporting the Ames community!

Supporting Pollinators = Supporting Our Food

A pollinator is any animal (insect, bird, mammal) that moves pollen between flowers (the Ames Pollinator Plan focuses on supporting native bees, butterflies, moths, and other insects). The pollen exchange facilitated by pollinators allows plants to be fertilized and consequently grow fruits and seed. The fruits and seed produced with the help of pollinators is infinitely important! About one-third of our global food supply depends upon pollinators. If you like almonds, apples, tomatoes, or even steak and butter, you have pollinators to thank. Wait, steak and butter? Yes indeed. Pollinators are very important in producing seed for growing alfalfa, a hay crop fed to beef and dairy cattle. Without hay in livestock rations, it would be harder to access all things cattle, from ice cream to beef tacos. Lastly, almost 90% of flowering plants depend on pollinators! If you like seeing wildflowers on hikes or along roadsides, then you should want to keep pollinators around. Imagine if we lost nearly all of our flowering species? Our landscapes would be quite boring and colorless, and our plates would look more empty.

Supporting Pollinators = Supporting Ames’ Natural Resources

Yes, pollinators are very important for food crops at the national and global scale. But what are some benefits that we will be able to see locally, here in Ames? We’ll list two: 1) our water quality and 2) our soil health could be improved by planting pollinator habitat. One of the best ways to support pollinators is by planting native vegetation, or plants that have evolved and are originally from Iowa. Pollinators eat the nectar and pollen of these plants, and some also create nests in their stems. Many native plants are perennial, and because of this have expansive, thick root systems. Planting a patch of native plants is similar to casting a thick, wide net underground. This net of roots holds soil in place on slopes, soaks up extra water during heavy rain, and absorbs excess chemicals such as fertilizers and pesticides as water moves through. These actions provided through native vegetation will lower erosion, mitigate flooding, and keep our local waterways cleaner if planted in the right areas.

Pollinator habitat also supports water quality!

Planting for pollinators is also planting for people.

Additionally, because these plants are well-adapted to Iowa, they need fewer inputs such as pesticides and thrive without fertilizer. This creates a low-input, sustainable planting system. Lastly, creating a good pollinator habitat will create a good human habitat (see graphic on page 4 of link). Bear with me here. Being surrouned by greenery and wildlife such as butterflies reduces stress and stimulates curiosity and creativity. Strategically planting more diverse vegetation and flowering plants may increase the observations of birds, butterflies, and other wildlife, which could have a positive impact on the mental health of Ames residents. This plan will support the pollinator community to address food insecurity, ecological health, offset the impacts of climate change, and will serve as an example for other cities around the world. Supporting pollinators truly supports the Ames community and beyond!

So What’s in this Plan?

The vision of the Pollinator Plan is for the City of Ames “to become a leader in developing and sustaining pollinator habitat that will enrich the quality of life for the human and biological communities of Ames“. Besides creating habitat that benefits pollinators and people, this plan also contains four pathways to bring this vision to life: 1) public education about pollinators and other important wildlife in Ames, 2) policy enhancements to support habitat implementation in the city, 3) research current and future conditions for pollinators and residents, and 4) the creation/strengthening of partnerships to use all resources to the fullest potential. Through education, policy, research, and partnerships, our plan will leverage the excitement and interest in pollinators to reach a beautiful vision of Ames: a more engaging, sustainable, beautiful, and healthy place that will not only serve pollinators, but the people and visitors of Ames.

Which Insects are “Home for Christmas”?

Which Insects are “Home for Christmas”?

Happy Holidays!

Insects are conspicuous by their absence during Iowa’s winter months. Absent are the beauty of butterflies, and we would be shocked to hear a bee buzzing around our snowy apartment balcony on Christmas Eve. So where did they all go? Did they perish from freezing temperatures? Have they all migrated south with the eastern monarch butterflies?

Here in Iowa, we have many insects that use truly astonishing techniques to stay here throughout the winter, braving the cold with the rest of us. From smart hiding places and suspended animation to making their own antifreeze, Iowa’s insects have developed some pretty wild adaptations to weather the winter!

Note: Iowa has many insects that undergo “suspended animation”, technically called diapause, to survive winter. Diapause is an insect form of hibernation where the insect pauses development; it stops maturing and halts all activity. It remains in its’ current life stage (which could be egg, larva, nymph, pupa, or adult) until conditions become favorable again and they can continue growing or start mating/laying eggs.

Wooly bear caterpillars: These fuzzy little guys will mature to become the Isabella tiger moth. They stare winter down by allowing themselves to freeze, but on their own terms! They seek shelter under logs and leaf layers. Once safe, they go into diapause and slow down the freezing process by creating glycerol, a natural alcohol and one of the many insect forms of “antifreeze”. They slowly allow their entire bodies to freeze except the insides of their cells.

Black swallowtail butterflies: These beauties stay cozy in their chrysalis while the snowflakes fall, entering diapause at the pupal stage. Their chrysalis mimics a dead leaf to keep them safe from predators, so be careful when cleaning up your lawn – especially if you grew dill, parsley, or other plants related to carrots in your garden! If you must move leaves, try not to chop/mow them to ensure you can enjoy the swallowtails next summer!

Dragonflies: Dragonflies brave the winter in a few different ways depending on the species. Some overwinter as eggs laid in logs near ponds, and others actually migrate. But one of the coolest ways some overwinter is as underwater nymphs (an immature stage of a dragonfly)! The dragonfly nymphs stay underwater beneath insulating ice layers, where they are voracious predators true to their namesake (even eating small fish!). They eat and grow throughout the winter until they can emerge as adults in the summer.

Dragonfly Larva

Flower flies: Also known as syrphid flies or hover flies, flower flies are a family of flies (called “Syrphidae”) that are fantastic garden helpers: when young they eat aphids, and as adults they pollinate. Here in Iowa, they’re commonly referred to as “sweat bees” due to their black and yellow stripes and the fact that they sometimes land on sweaty humans (sweat contains good nutrients for them). However, these flies only mimic bees, and cannot sting or bite (their mouth basically consists of a tiny mop). They survive the cold much like other insects; they find shelter in leaf layers and other plant material, enter diapause and overwinter as a larva, pupa, or adult depending on the species. Flower flies are no pansies!

Bumble bee queens: Bumble bee hives only live for one year, unlike honey bees. Near the end of the hive’s life, new queens and male bees (“drones”) hatch and leave the hive to mate. When hive activity finally ends, the drones die while the newly-mated queens search for a warm winter home alone. Their new homes could be in leaf layers, warm compost piles, or just a few inches underground in a sheltered place! While winter winds howl, the entire fate of next year’s bumble bee hives rests on these young queens surviving the winter all alone. When it warms again, if all goes well, they will wake from diapause and emerge to start their very own hives to begin the cycle again.

How Can You Help?

As you can see from these few examples, surviving winter is key to us enjoying pollinators and other insects next year. So many insects rely on the shelter of leaves, logs, and other materials to block the cold wind and insulate them from freezing temperatures. Therefore, one of the best ways to help pollinators this winter, and to ensure there are pollinators this summer, is to find a place in your yard or balcony where you can let leaf litter and plant material accumulate. Think of it as a Cozy Corner that may harbor young bumble bee queens, sleeping swallowtails, and fuzzy wooly bear caterpillars. Give insects the gift of cozy this holiday season!

See below for more information on how to build your very own Cozy Corner:

Small Brush Pile

Create a “Cozy Corner”
You can create a “cozy corner”, or brush pile, for pollinators throughout the fall and winter by choosing a location to leave leaf litter undisturbed. You can add twigs, branches, and other brush to the pile as you clean up the other areas you want clear of brush. You can also leave potted plants on your balcony or patio and push them together to create a small shelter; I’ve found moths sheltering in my flowerpots in mid-fall, and I’ve noticed more bird visitors! Add layers of brush to your cozy corner to provide the best shelter possible. Click here to read the full article from which this paragraph was based on.
