It’s National Pollinator Week!

National Pollinator Week was started by the Pollinator Partnership and approved and designated by the U.S. Senate 15 years ago. It’s a celebration of pollinators and what they do for us. It’s also a time to raise awareness about pollinators and their declining populations. If you love nature, gardening, and pollinators, it’s a wonderful week to get involved.

  • There are about 350,000 species of pollinators worldwide. These species include birds, butterflies, bees, flies, bats, moths, beetles, wasps, small mammals, and even lizards!
  • Native pollinators, especially bees, are estimated to contribute $3 billion to the value of crop pollination in the U.S..
  • The southeastern blueberry bee is an excellent example of the importance of native pollinators. In her few weeks as an adult, a single female bee visits about 50,000 blueberry flowers, resulting in over 6,000 marketable blueberries worth about $75.
  • There are approximately 4,000 native bee species in the United States, 10% of which have not been named or described.
  • About 20%-45% of native bees are pollen specialists, meaning they use only pollen from one plant species (or genus). They often do a better job with these plants than non-specialized species. 
  • Most plants, more than 70 percent of species, depend on pollinators for reproduction.
  • Pollinator decline has been reported on every continent except Antarctica.
  • Estimates showed that wild bees declined 23 percent across the United States between 2008 and 2013. 
  • There are several factors causing pollinator decline, including diseases and pathogens, conversion of natural habitats to row crops, pesticide use, and habitat loss and fragmentation.

Identifying Pollinators

From moths to bumblees, identifying specific species of polliantors, particularly insects, can be challenging. Today, there are many apps that can help along with some quality guidebooks like Common Bees of Eastern North America by Olivia J. Messinger Carril and Joseph S. Wilson. 

Another great resource is iNaturalist, a joint initiative of the California Academy of Sciences and the National Geographic Society that allows you to share observations and get confirmed identifications from other naturalists.

2023 National Pollinator Week

The 2023 National Pollinator Week is focused on the connection between pollinator decline and climate change. They now face increased disease pressure, food source and habitat loss, rising temperatures, and more frequent natural disasters, all of which have impacted their ability to survive.

  • Find Pollinator Week activities in your area or add your own activities to the map and invite others to join in. 
  • Build an insect hotel or native bee house. 
  • Plan or start a pollinator garden.
  • Share information about pollinators on social media.
  • Host a native plant and seed sale or exchange. 
  • Watch or screen a pollinator documentary. 
  • Eliminate pesticide usage in your garden. 
  • Write to local, state, or federal officials and encourage them to take climate change and the plight of pollinators seriously.
  • Turn more of your lawn into garden or native plantings. 

Ideally, we think about pollinators and do right by them every day. However, Pollinator Week is a good time to reflect on our current practices and encourage others to do so as well. It can be as simple as talking about pollinators with your family and friends or sharing some native seeds with a neighbor, or as involved as campaigning for systematic changes in your state or community. 

Pests & Pollination: Attract Beneficial Insects

Last week we discussed strategies for conquering weeds in an organic garden. This week we’re moving on to another chore loathed by natural farmers, gardeners, and growers everywhere, controlling pests. One excellent way to ensure pest populations don’t get out of control is to ensure you have plenty of beneficial insects. When we think of beneficial insects, we often think of pollinators like bees and butterflies, but insects have so much more to offer us, gardeners! Many beneficial insects prey on pests and their eggs and larvae. Learn how to attract beneficial insects to your garden.

What are Beneficial Insects?

Beneficial insects help us in the garden by pollinating plants, feeding on pests, and parasitizing pests. In our area, some of these include:

  • Wheel Bug (Arilus cristatus)
  • Wolf Spider (Lycosidae spp.)
  • Rusty Patched BumbleBee (Bombus affinis)
  • Black Swallowtail (Papilio polyxenes)
  • Carolina Mantis (Stagmomantis Carolina)
  • Yellow Garden Spider (Argiope aurantia)
  • Orange Sulfur (Colias eurytheme)
  • Braconid Wasp (Cotesia congregates)
  • Damsel Bugs (Nabidae spp.)
  • Mabel Orchard Orbweaver Spider (Leucauge argyrobapta)
  • Southeastern Blueberry Bee (Habropoda laboriosa)
  • Lacewing (Chrysopidae spp.)
  • Big-Eyed Bug (Geocoris spp.)
  • Blue Orchard Mason Bee (Osmia lignaria)
  • Striped Lynx Spider (Oxyopes salticus)
  • American Copper Butterfly (Lycaena phlaeas Americana)

These are just a fraction of the insect species hard at work in our yards and gardens! Of course, there are beneficial animals too. Birds and bats can also help keep pest populations down and pollinate plants.

Habitat Features to Attract Beneficial Insects

All these helpful insects need a habitat that provides the essentials of food, water, and shelter, just like we do. 

Don’t Clean Up Too Much

Many beneficial insects need places for themselves or their eggs to overwinter. Blue Orchard Mason Bees, for example, overwinter their eggs in cavities in plants like the hollow stems of flowers or reeds. Depending on the species, Lacewings over winter in their adult or pupa stage in piles of dead leaves or other organic debris. Resisting the urge to keep your garden spotless can provide these insects with better habitat.

Plant a Windbreak

Sometimes, gardeners will plant windbreaks to help with wind-related issues like lodging corn, but few people probably consider that it makes life much easier for beneficial insects. A windbreak or hedgerow can help slow wind through your garden, creating calmer flying conditions for bees, dragonflies, lady beetles, and other flyers.

Provide Water

Especially in the hot dry days of summer, insects need water just like people do. If you have water on your property like a pond or creek you can help keep it full and cool by allowing the banks to grow in trees and shrubs that will shade it. If you don’t have a natural water source, don’t worry you can make an insect waterer! All you need is some sort of clean small trough and stones to place in it. The stones are critical, as insects need an easy way to get down to the water and to climb out. Change the water regularly. 

Avoid Pesticides of Any Kind

Sometimes when we see the organic label we assume something is safe. Unfortunately, it isn’t that simple. Organic pesticides may be much safer for people and often waterways than conventional pesticides. However, both conventional and organic pesticides kill insects and neither of them differentiate between types of insects. If you have something that kills caterpillars to get rid of the cabbage loopers any swallowtail caterpillar that comes into contact with it will be effected too.

Flowers & Plants that Attract Beneficial Insects

Flowers aren’t just for bees and butterflies! Lacewings, parasitic wasps, lady beetles, and other insects use them too. For example, the larval stage of Convergent Lady Beetles feeds on insects, but the adult stage feeds on nectar, pollen, and honeydew. The females need a certain amount of these foods before laying eggs.

Conversely, many species, including bees and butterflies, need plants that aren’t in their flowering stage. For example, the caterpillars of the Black Swallowtail Butterfly will feed on the leaves of carrots, dill, fennel, and parsley.

Selecting Plants & Flowers

While poppies, roses, tulips, and hydrangeas are all stunning flowers that are great for human enjoyment, they may not be a favorite among beneficial insects. Flowers that are native or user-friendly typically will attract and support more beneficial insects.

Native Plants
Native Shrubs
  • Eastern Sweetshrub (Calycanthus floridus)
  • Southern Highbush Blueberry (Vaccinium formosum)
  • Allegheny Serviceberry (Amelanchier laevis)
  • False Indigo Bush (Amorpha fruticosa)
  • American Beautyberry (Callicarpa americana)
Native Trees
  • Eastern Redbud (Cercis canadensis)
  • Sourwood (Oxydendrum arboreum)
  • Tulip Poplar (Liriodendron tulipifera)
  • Sugar Maple (Acer saccharum)
  • Black Cherry (Prunus serotina)

Your local extension agency may also be able to provide more information on native species specifically suited to your area.

User-Friendly Flowers

Generally, beneficial insects find get the most food from a few different types of flowers: those with flat umbels of tiny flowers (looks a bit like a lace umbrella) like Queen Anne’s Lace, those with daisy-like flowers made up of tiny flowers like sunflowers, and those with loose spikes of tube-like flowers like mint.

These are just a few plants beneficial insects love. While it’s still perfectly fine to have and enjoy other flowers and plants, it’s important to plant some that consider our local insects.

Incorporating these strategies into your garden plan can help you attract beneficial insects and have a successful season. Happy growing!

 

 

10 Plants to Attract Beneficial Insects to Your Garden

Many insects play vital roles in helping our gardens grow. Flies, bees, butterflies, and moths pollinate crops while spiders, beetles, mantids, parasitoid wasps, lacewings, and other predators feed on pests. On the soil level, worms, millipedes, and other decomposers help turn organic matter into usable nutrients for your plants.

Attracting some of these insects to your garden can reduce pest pressure, help build healthy soil, and improve yields. Here are ten plants you can grow this season to help attract some of these important insects to your garden:

Buckwheat

Buckwheat

This tasty grain and fantastic green manure crop is also excellent for attracting pollinators and parasitoid wasps. It grows quickly, and both wasps and bees love the flowers! Sowing a patch and have it buzzing with activity when flowers appear in as little as six weeks!

Dara

Dara

This delicate flower is closely related to Queen Anne’s Lace but isn’t as aggressive in the garden. The flower clusters in pink, dark purple, and white attract various pollinators, including tachinid flies that parasitize squash bugs.

Creeping Thyme

Creeping Thyme

Slow-growing at first, Creeping Thyme will eventually form dense mats. This thick ground cover provides excellent shelter and shade for predatory beetles as well as decomposers like millipedes.

Bronze Fennel

Fennel

Fennel has beautiful delicate flowers that attract tiny wasps and other pollinators. Its leaves are also a food source for some swallowtail butterfly caterpillars.

Mint

Mint

Like thyme, mint is a great way to create dense shady areas of foliage that are multi-purpose. You can harvest mint for tea and culinary uses while it provides habitat for decomposers and predatory beetles. The flowers are a favorite with bees.

We’re currently out of stock of mint seed, but you may be able to get a start from a friend. Alternatively, other plants in the mint family that work well include lemon balm or anise-hyssop.

Sweet Alyssum

Sweet Alyssum

Sweet Alyssum forms low, spreading mounds with fragrant, tiny white flowers that are excellent for attracting bees, butterflies, and other pollinators. It’s long-blooming, especially when spent blooms are cut back. It also provides shade and shelter for ground-dwelling beneficial insects.

Echinacea

Echinacea

This native flower can help you attract a variety of butterflies and bees to your garden. It’s also drought-tolerant and medicinal.

Dill

Dill

Like fennel and Dara, dill’s tiny flowers are attractive to many small beneficial insects, including parasitoid wasps, flies, and bees. It will do double-duty when it’s time to make pickles!

Rudbeckia

Rudbeckia

Sometimes known as Black-eyed Susan, it has composite flowers which will attract bees, hoverflies, parasitoid wasps, and robber flies. It’s also a great low-maintenance planting for an untended space. Rudbeckia self-sows and naturalizes aggressively.

Zinnias

Zinnias

These are the workhorse of any flower garden. Zinnias are easy to grow and will bloom all summer, especially if you keep up with deadheading. They’re excellent for attracting bees, butterflies, and other pollinators.

Additional Tips

  • Avoid using pesticides. Even organic pesticides can negatively impact beneficial insects the same way that they’re intended to harm pests. Opt for integrated pest management instead.
  • Let things get a little messy and provide natural, wild habitat whenever possible. Let part of your lawn grown, leave standing dead plant material, don’t get rid of autumn leaves, and let trees and shrubby areas grow. 
  • Build an insect hotel! You can find instructions here.
