Hymenoptera in My Garden

0912171558

For those with a fear of bees (apiphobia) or wasps (spheksophobia), now is not a good time to hang out in my garden. The overgrown sedum, in particular, is crawling with pollinators, one on top of another: bumblebees, wasps, hornets, flies, and the occasional moth or butterfly (just to tone down the terror factor a notch).

The sedum is called “Autumn Joy.” I guess I forgot to ask, “Whose joy?” Not my husband’s, certainly, but maybe these guys’?

In another flower bed just a few feet away, I noticed a large concentration of wasps investigating my tiger lilies.

At first, I wasn’t sure what could be so interesting about these bare stems, the blooms having vanished almost two months ago now. When I went in for a closer inspection, however, I found hundreds of tiny insects beneath the leaves.

These purple spotted lily aphids (macrosiphum lilii), destructive little pests, apparently make a fine meal for the visiting hymenoptera. So, while I don’t generally make it a point to encourage wasps to gather near my deck, I’ve decided to make an exception and let them feast for as long as they like. Because it’s nice when the garden takes care of itself.

Out front, I found another insect predator grappling with its insect prey. Generally, I see cicada killers (sphecius speciosus) hovering near their holes in the hardened mud by the river, but the droning buzz of cicadas had drawn this one into my front yard, where, despite its generous size, it was struggling to lift a cicada and transport it back to its nest.

My boys and I watched for a few minutes, (giving me time to feel a little sad because I happen to like cicadas and have written about them before) then went back to our work in the driveway. I even forgot about it until a sparrow flitted past my view carrying something large in its beak. When it landed on my front walk, I saw it drop a cicada, which it began to devour quite happily. Bird trumps insect. This time, anyway.

 

Zinnias

Zinnias. They’re not native to Maryland, preferring the hot, dry locales of the southwest and Mexico, but I love to plant them in my garden. In the early spring, I buy a few seed packets, pull my own baggies of last year’s seeds out of storage, and spread them over bare soil that will be dry and hard by August. I rake the dirt over them a bit (maybe), sprinkle some water on top, and leave them. As the tulip and daffodil leaves begin to shrivel, the zinnias begin to sprout, and when the butterfly weed has begun to wane, the zinnias grow taller, and as the coneflowers think of fading, the zinnias bloom. I plant a variety of low-growing zinnias so close together that they create busy bouquets

as well as the more classic, tall varieties, some so tall that I need to stand on tiptoes to photograph, which bloom in a plethora of color and a profusion of petals.

They’re a favorite of bees and butterflies,

but it’s the resident hummingbirds that draw the most attention, zooming between our honeysuckles and vegetable garden out back — ceding the sunflowers to the goldfinches for the most part — and the zinnias out front. One morning our old labrador, Poppy, startled one when she stepped outside for her morning constitutional. It zipped away momentarily but soon returned to consider this bear-shaped, heavy-breathing mammal. Poppy, either sensing its superiority or hoping that it might want to play, promptly rolled over for it. The hummingbird simply ignored her and tended to the flowers, but, really, what else could it do?

Huh. Now that’s a book waiting to be written.
