Perhaps post-equinoctial would be more appropriate, as this immature male Twelve-spotted Skimmer (Libellula pulchella) was encountered on September 24th, 2014 at the Tweed Fairgrounds (south-central Hastings County, Ontario).

Striking – arresting the attention and producing a vivid impression on the sight or the mind, attracting attention by reason of being unusual, extreme, or prominent, conspicuously attractive or impressive.

East of Tweed, near a patch of wildflowers along Lakeview Lane (44.478429°, -77.301881°) – my third sighting of a Saffron-winged Meadowhawk this year (the other two were at Dry Lake, south of Marlbank). Sympetrum costiferum is larger – this individual measured 38 mm – and darker than the average Sympetrum apt to be encountered in our area, and it has a habit of perching on the ground.

A hybrid between two very different looking species, the New England Aster (Symphyotrichum novae-angliae) and the Heath Aster (Symphyotrichum ericoides), the Amethyst Aster (Aster x amethystinus) exhibits characteristics of both parent plants which, not surprisingly, were abundant in the high and dry field where the Amethyst Asters were encountered.
The following groups of three photos illustrate the features of the Amethyst Aster, New England Aster and the Heath Aster respectively.

Encountered west of Tweed near a marsh bordering the trans-Canada Trail (44.46889°, -77.31528°) – a surprising find as the final few surviving Common Whitetails (Plathemis lydia) were flying nearly a month ago, and no others have been sighted until now. The last sighting in this area was a male on August 18, 2014 near the intersection of River St. and the trans-Canada Trail (44.473668°, -77.312911°).
The dulled colors aside, this female is in really good condition with no wear and tear on the wings, it was extremely wary and alert and it sure could fly. Half an hour of patient stalking were required to capture the agile odonate.

At first glance the Lake Darner looks very similar to the Canada Darner. The main distinguishing characteristics are the distinct dark cross-stripe on the face, the very deeply notched anterior thoracic stripe and a second thoracic stripe that is relatively broad compared to other Aeshna species.

Theoretically, in the best of all possible worlds a stinkhorn can expand from its immature "egg" stage to full size within thirty minutes. It actually takes several days to produce the nascent fruitbodies (primordia), but once formed, the fungus can bulk up rapidly by taking in water.
The following series of photos illustrating the growth of a Ravenel's Stinkhorn (Phallus ravenellii) spans about seven hours, maybe not fast enough to win any medals in the Fungal Olympiad 100 mm dash, but still a respectable rate of growth.
