Holes are a good thing.
Holes in wood and masonry and bare ground and leaves suggest that pollinators are at work and planning for the next generation.
Continuing the celebration of National Pollinator Week, let’s talk about those critters making the round holes: let’s talk native, or wild bees. According to the U.S. Geological Survey on native bees, there are roughly 20,000 native bee species in the world, about 4,000 of which are endemic to the U.S. Native bees are found on every continent (except Antarctica) and are some of the most important, if unnoticed and unappreciated, of the hard-working pollinators.
Many native bees are so tiny that you wouldn’t see them unless you’re really looking.
Other native bees, like this Horsefly-like Carpenter bee, Xylocopa tabaniformis, are larger.
Native bees are remarkably beautiful.
Regardless of size or looks, native bees are the bomb when it comes to pollinating abilities. They are some of the best and most efficient pollinators you’ll ever want to invite into your garden.
Not all native bees make holes in wood or leaves and petals for their nests, but they all need certain environmental qualities to live and thrive. We know that native bees are declining and some of the common reasons are as follows: reduction of habitat, pesticide use, lack of pollinator plants.
How can you be a part of the solution to slow the native bee decline? Make your garden welcoming to these important creatures. Many native bees (like bumblebees) nest in the ground. You can allow a portion–it doesn’t have to be a large area–of your property to host some bare soil: no mulch, no cement, no hardscaping, no garden or turf of any sort. I keep a fenced-off work and storage area where my compost bin is located. It’s not mulched, though I’ve allowed some native plants to seed out. (I just can’t help myself.) To some eyes, it’s “messy,” but to native bees’ eyes, it’s a welcoming neighborhood with good homes for their babies. And we all want good homes for our babies, right? A sterile, uber-clean look is not something that native bees like. While I haven’t spent much time searching the area for bees’ nests, I have noticed that my gardens host more native bees since I allowed this area some wildness.
Many home gardeners are building native bee/insect hotels and that’s a fun way to help native bees find protected homes for their offspring.
I wrote about my insect hotels here, but there’s plenty of information available on the Internet or through garden resources about building insect hotels or houses. These are simple and fun projects to do with kids.
One of the easiest things that will allow native bees to settle in to your garden is to leave firewood (that you won’t use) or downed tree limbs on your property.
Certain species drill into wood and lay their eggs, so it’s a effortless way to ensure that they have a safe home for their bee babies.
I’ve laid logs of wood in various spots around my garden; bees have no trouble finding the wood and getting to work making nice homes for their families. If you cut down a tree, keep some of the wood and maybe even the stump. You can drill holes to give your native bees a head start, or leave them to it. Either way, it’s a win and native bees and your garden will be healthier for it .
Another way to help slow the decline of native bees in your area is to refrain from pesticide use. There are myriad reasons why home gardeners shouldn’t rely on pesticides, but allowing native bees to nectar and collect pollen, and to create those cool holes in leaves for their nests, are but a couple. Remember that pesticides kill–that’s their job. For example, if you’re spraying for adult mosquitoes, the pesticide will kill bees, butterflies, moths, and all other insects that the chemical comes in contact with. Pesticides don’t discriminate–they kill all “pests”, aka, insects.
Plant for pollinators!! That’s the fun part. It’s best to use native bloomers if you can get them.
If native plants are not readily available, choose well-adapted, non-native perennials and annuals and have fun planting!
Don’t forget that flowers bloom in seasons other than spring–plant for year-round flowering (even in winter if you live in a mild climate) so that pollinators are kept busy and happy. You’ll enjoy the beauty of the blossoms and the insects that visit and you’ll help repair the world in your own back yard. And front yard too!
When my children were little, we enjoyed observing the the visits of giant, gentle bumblebees–you know the type, the huge black, yellow and fuzzy bees. The bees were especially fond of a large salvia shrub with blue blooms and at times, there were 20 or 30 of these bees working the blooms all at the same time. They were fascinating to watch–so focused and single-minded as they gathered nectar and pollen and so gentle, that I could pet them. (I didn’t do that in front of my little ones. No sense in encouraging that!)
There was a field not far from our street, full of native wildflowers and grasses. Of course, it was going to be developed at some point and in fact, two new neighborhood streets with tidy little single family homes were built over the field. From a neighborhood perspective, it was the best possible outcome; certainly better than a hotel or yet another shopping center. But after the construction began, we never saw the bumbles again.
I recently saw a giant black and yellow and fuzzy bumblebee in my back garden. I only saw her twice, didn’t get a good photo of her, but she was there, early two mornings, working the flowers. I have no idea where her home is. I can only hope there are more like her and that they have a safe ground home somewhere and plenty to survive on.
Pollinators are life–they pollinate the food we eat, products we use, and they make the world a lovelier and more interesting place in which to live. Pollinators deserve our attention and respect; they deserve to live. If you don’t have a pollinator garden, well, why not give it a whirl? It’s not hard to plant for pollinators–you’ll be amazed by their beauty and impressed with their work ethic.
Happy National Pollinator Week!
