Bee-ing with Halictus, the Sweat Bee – #3 in the series
June 24, 2020
A knee injury for me (again!) is the perfect excuse for more bee-ing, less working in the garden.
Couple that with National Pollinator Week, and I’m feet up, ice-wrapped, coffee in hand and all a-buzz to share with you what I’ve seen.
After dinner at the picnic table last night (yay summer!), I spied this charmingly striped bee working over the yarrow blooms.
Meet your friendly neighborhood Halictus. Now, this has never happened to me and I’m not sure how I would react if it did, but these bees will lick the sweat from people’s skin and so, they’re known as sweat bees. Weird, huh!?
Also weirdly interesting, unlike most native bees that are solitary, Halictus are true social (or eusocial) bees like honey bees and bumble bees. Social bees have a queen and workers that live together in a nest. But sweat bees are unique in that every female worker retains their ovaries. If conditions are right, she can head off to start her own nest laying eggs for her own workers. That’s a pretty cool adaptation! It gives Halictus the ability to respond to varying weather or abundance of floral resources by expanding their populations.
How can you support these pollinating super stars?
*Plant a lot of flowers! Halictus are generalists (feed from many species) and are active over an extra long season. So, the more flowers in your garden throughout the seasons, the happier your local sweat bees will be. The yarrow (Achillea millefolium) in my garden is a big hit with the sweat bee as well as a lot of other pollinating visitors. Colored varieties like ‘Terracotta’ and ‘New Vintage Rose’ are fun, too. I like how yarrows will re-bloom if you cut them down after their first flush. Meadow sage (Salvia nemorosa) is another that can be treated this way. Meanwhile, long blooming plants like ‘Rozanne’ geranium are a boon for the lazy pollinator gardener – no need to deadhead this one!
*Leave some area of your yard bare – no mulch, no plants. Halictus and most other native bees are ground nesters, tunneling into hard, bare earth. Have you seen small holes in a neglected corner of your yard? Celebrate! You have native bee nests! In a small yard, it can be hard to set aside a bare patch. Expand your view of your garden to include the nearby alleys and neglected hellstrips. With a little attention and communication with neighbors, these public nooks of land can be protected for nesting bees.
*Provide shallow water. The mossy rocks on the edges of our boulder fountain are alive with thirsty bees all summer. A terra-cotta tray with pebbles and fresh water is another way to offer a drink. Even large-leaved plants that catch sprinkler water can be included in the pollinator garden for their puddling contributions. Lady’s mantle (Alchemilla mollis) and annual nasturtiums have excellent water holding leaves. Even our native wood sorrel (Oxalis oregana) keeps water droplets adhered to their leaves as if they were made of velcro. Pass more time bee-ing and you might see the wonder of a proboscis drinking that droplet down right in your own garden.
This summer, whether you’re able-bodied or not, relax a bit more in your garden and spend time bee-ing. Watching the flying visitors is a wonderful way to de-stress and connect to nature.
And, if a little striped bee helps itself to a lick of your salty sweat, try to curb your reaction to swat it away! It’s recognizing you as part of the habitat. 😉
