Tweed, Ontario, about ½ km west of town, a marsh bordering the trans-Canada Trail:
typical local marsh with Cattails, sedges and other emergent vegetation, various small willows, alders, dogwoods and some Tamarack.
|
|
Teneral Whiteface (Leucorrhinia), newly emerged.
Length of teneral about 30 mm, exuviae length about 16 mm.
During the peak of the flight season hundreds of emerging dragonflies can be found in the vegetation bordering the marsh
(May 22, 2011).

Teneral Four-spotted Skimmer (Libellula quadrimaculata), newly emerged.
Length of teneral about 40 mm (after the abdomen was fully expanded), length of exuviae about 20 mm.
Another species that emerges en masse at this time of year
(May 23, 2011).

Tweed, Ontario, the north shore Stoco Lake, on the boat pier:
marshy shoreline, relatively shallow water with mud bottom supporting sedges and rushes, pondweeds, Fragrant Water Lily, Blue Flag, Sagittaria spp and Pickerelweed.
|
|
Unidentified Skimmer (Libellulidae) exuviae –
between 20 mm to 25 mm in length.
Judging by the large numbers of tenerals in the area
they might belong to Widow Skimmers (Libellula luctuosa)
(June 18, 2011).

Tweed, Ontario, the Moira River, near the walking bridge and dam:
rock-bottomed river with fast flowing water, rapids and emergent rocks, but also quiet pools and backwaters.
The shoreline vegetation is mostly trees with a few small clearings supporting tall grasses and wildflowers.
|
|
Aspects of an unidentified Skimmer (Libellulidae) exuviae –
about 15 mm long.
Considering their size, habitat, season and the adults flying at this location
the exuviae are probably one of the Meadowhawk (Sympetrum) species
(August 17, 2013).
