Mid-afternoon at the Fletcher Wildlife Garden, August 14th. A sunny and pleasant afternoon to be looking for things to photograph for the PBase Blog. My first sighting was of the Sphex ichneumoneus, the Great Golden Digger as it is sometimes called, nectaring on swamp milkweed. Its counterpart, the Great Black Digger, S. pensylvanicus, is often more numerous, but both are large and impressive.
Other insects found include numerous Acutalis treehoppers, one of our smallest treehoppers, tiny little green and black insects, usually found on the stems of plants such as goldenrod. The large (for a planthopper), Acanalonia bivittata, with its distinctive shape, is easily recognized. It is bright green, with reddish eyes and a dark stripe down its back. It also comes in a vivid pink form, something I’m still hoping to see. The large swathe of Monarda fistulosa, our beautiful lilac-coloured native species, in the butterfly meadow, is alive with bees and other nectaring insects, including a Hummingbird Moth and a very tattered Silver-spotted Skipper. The big Bicyrtes sand wasp, smaller mud daubing wasps, sweat bees, leaf-cutter bees, ragweed beetles, Goldenrod Leaf Beetles, the predatory larvae of Green Lacewings sometimes called aphid lions because of their propensity for feasting on aphids, Pennsylvania Leatherwings (soldier beetles), tiny ragweed fruit flies, and a host of other insects can be found on the abundant flowering plants around the site.
In addition to the skipper, lots of cabbage whites, a few White Admirals, and several newly emerged ringlets, the second generation in our area, were also seen.
Birds are vocal and active, with broods of young following the adults, calling and begging for food. House wrens are especially vocal these days, as are catbirds and song sparrows. Robins, Baltimore Orioles, Chipping Sparrows, Black-capped Chickadees, Northern Cardinals, Cedar Waxwings, and many other birds are very noticeable right now. While our Tree Swallows have long gone, Barn Swallows can still be found swooping over the garden. Shrubs such as elderberry and Tartarian Honeysuckle are providing much food for birds. Diane and I watched a Cedar Waxwing guzzling down the fruit of the honeysuckle as if he couldn’t get enough!
It is fascinating to see how the vegetation changes from year to year. New plants appear in odd spots, others vanish. All the annuals found last year in the old field’s rototilled section, have gone, but in their place scores of the biennial Evening Primrose (native plant), some big Scotch (or Bull) Thistles, much beloved by insects, especially bees, and a variety of other species. The native wild cucumber plant is sending its sprays of creamy white flowers up in various spots including in the old field area.
There are lots of photos on the August 2013 Blog here:
Be sure to visit so you can also see the great photos submitted by Diane and France, who photographed a gorgeous giant swallowtail at the garden on August 15.
Thank you for such informative articles – love them! My mountain mint draws the digger wasps by the handful, and we even had the golden ones “digging” in bare patches of our lawn a few years ago. Continue the good work at Fletcher. Ottawa is all the better for the work all of you do.
Thanks for sharing this information, Barb! We’re always eager to know what wildlife is attracted to what plants and other features of gardens.
