Damsel or Dragon?

Dragonflies and damselflies are two related groups (suborders) that make up the insect order Odonata. Although very similar in many ways, they are also very easy to distinguish.

Dragonfly adults have a rather robust body, and perch with wings held out to the side. Their eyes are huge, often meeting at the top of the head. The bodies of damselfly adults are quite slender, and for most species the wings are folded together over their abdomen while at rest. While their eyes are very large, they are set somewhat to the side of the head rather than dominating the front.

Dragonflies are swift and strong fliers, reminiscent of tiny airplanes, while damselflies have a rather fluttering flight.

Their aquatic nymph stage is also quite distinct. Damselflies have three leaf-like gills at the tip of their abdomen, while the more robust dragonfly nymphs lack these. Damselfly nymphs swim with a side-to-side “snake-like” motion, while dragonflies spurt water out through the anus to swim with a “jet-propulsion” type of movement.

Dragonflies


Family Aeshnidae (Darners)

Dragonflies in this family are large-bodied insects with noticeable finger-like projections at the end of their long abdomens and possess large compound eyes which meet each other at the top of the head. They are strong fliers, difficult to catch and most perch in a vertical position.

Canada Darner

Scientific name: Aeshna canadensis

Length: 64 -73 mm

Description: a large brown dragonfly with two stripes on each side of the thorax and relatively large spots on segments three to ten; the first stripe has a deep notch and resembles a thorn. On males, the abdominal spots are blue; the stripes are often blue at the top transitioning to green at the bottom. Females have the same markings but may be all blue, green or yellow. The face is pale green with no heavy black line. Males have paddle-shaped claspers with a row of tiny bumps along the top.

Habitat: lakes, swamps, beaver ponds and streams – often seen patrolling shorelines and in darner swarms

Flight Season: end of June to beginning of October

Range: common across Ontario, except for southwestern Ontario, where it is uncommon

True Fact: The markings on this species darken when it is cold becoming brown or grey instead of blue, green or yellow.

Fawn Darner

Scientific name: Boyeria vinosa

Length: 60 -71 mm

Description: fairly uniform brown, two bright yellow to white spots on each side of thorax, smaller and paler yellowish spots on abdomen, wings dark brown at base

Habitat: shady streams and rivers, adults may also patrol ponds and lakes

Flight Season: June to October

Range: southern and central Ontario, west to Manitoba but south of boreal forest and absent north of Lake Superior

True Fact: This species may land on people’s legs while attempting to lay eggs (this is the source of the myth that dragonflies sting).

Green Darner

Scientific name: Anax junius

Length: 68 – 98 mm

Description: solid green thorax (hence name), abdomen bluish for males and reddish-brown for females

Habitat: lakes, ponds, marshes, slow streams

Flight Season: May to October

Range: southern and central Ontario to north shore area of Georgian Bay, west to Lake of the Woods areabut south of the boreal forest

True Fact: A large proportion of this species is migratory. Green darners returning from migration are often seen earlier in spring than other dragonflies. Their larvae develop in summer, emerge late in the season and fly south to the southern United States, Mexico or the Caribbean before returning in spring. This species is the only North American darner that usually lays eggs (oviposits) while the male clasps the female, flying in tandem.

Lance-tipped Darner

Scientific name: Aeshna constricta

Length: 65 – 73 mm

Description: male and female with blue to green diagonal stripes on thorax, not outlined in black, abdomen with many bold blue marks (female may have green or yellow marks), cerci (paired,finger-like extensions on tip of abdomen) large and lance -shaped (hence name) on females

Lance-tipped darner dragonfly, female

Habitat: often in seasonal ponds, especially marshy ponds and slow-moving streams

Flight Season: July to October

Range: southern and central Ontario to the northeastern shore of Lake Superior, and also reported from Lake of the Woods area

True Fact: Females are as brightly coloured as the males, and patrol over water like them, perhaps to avoid harassment. To avoid overtures from other amorous males, females will sometimes fly with their abdomens inclined downward.

Shadow Darner

Scientific name: Aeshna umbrosa

Length: 64 – 73 mm

Description: relatively dark darner, thorax with stripes outlined in black, light markings on abdomen pale and fairly small

Habitat: usually streams and rivers with moderate to fast current, sometimes lakes

Flight Season: June to September

Range: throughout the Great Lakes region west to Manitoba, including southern edge of boreal forest

True Fact:This species is well named, as it preys on dragonflies and damselflies. A particular favourite is reported to be the ebony jewelwing damselfly. They also prey on butterflies. This species is the largest of the clubtails.

Boreal Snaketail

Scientific name: Ophiogomphus colubrinus

Length: 41 – 48 mm

Description: bright green with distinct markings, dark facial stripes; male eyes green crossed by four narrow black lines, thorax mostly green, brownish abdomen with many greenish spots, enlarged “club” at tip; female similar coloration but abdomen thicker with less prominent club at tip, sides of abdomen marked with white

Similar Species: almost identical to Marsh Bluet, only differ in shape of terminal appendages

Habitat: ponds, marsh-bordered lakes, quiet streams

Flight Season: May to September

Range: throughout Ontario south of boreal forest region

True Fact: During egg-laying, like several other bluets the female will submerge, crawling around underwater vegetation.Upon resurfacing, the waiting male (or another) will re-attach to form a tandem pair again.Males seem to act as lifeguards, pulling floating females from water (for the purpose of mating, of course!).

Orange Bluet
