Wild About Illinois Dragonflies and Damselflies!

WADFBanner.JPGDragonflies and damselflies are insects in the Order Odonata. They have two pairs of long, membranous wings with many veins in them. The forewings and hindwings are usually similar in size but in some species the hindwing is broader at the base than the forewing. The abdomen is long and thin. The eyes are compound and very large in relation to the size of the head. The antennae are short and hairlike. The mouthparts are for chewing, and these insects are predators. The life cycle consists of egg, nymph and adult.

Nymphs are aquatic. They eat insects and other small animals. Depending upon the species, their gills are either in the rectum or external at the tip of the abdomen.

Adults are accomplished fliers that may travel many miles from their aquatic habitat. They often fly paired, with the male holding the female by the head or thorax with appendages at the tip of his abdomen. Eggs are either laid on aquatic plants or washed from the female’s abdomen into the water. The adults feed on insects that they catch in flight.

 Dragonfly Family and Species Gallery

Dragonflies have the base of the hindwings broader than the base of the forewings. The body is generally stout, and the wings are held outstretched (not closed together above the back) when at rest. The male has three appendages at the tip of the abdomen. The female has two appendages at the tip of the abdomen. Some female dragonflies have an ovipositor. Nymphs have internal gills.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Odonata
Family: Aeshnidae - These dragonflies are in the family commonly known as darners. This family contains the largest dragonflies in North America. They fly swiftly, and their body color is usually dark brown with marks of green, blue or a combination of these colors. The eyes are large and touch in the middle of the dorsal side of the head. The triangular section in each wing is approximately the same shape and in the same location. The ovipositor of the female is well-developed, and she has two appendages at the tip of the abdomen. The male has three appendages at the tip of the abdomen.

These species are usually found around ponds and swamps. The wings are held outstretched when not flying. The nymph has gills in the rectum and breathes by drawing water in through the anus, then expelling the water. This method can also be used to propel the nymph through the water. Like all dragonflies, the adults and nymphs are predators. Members of this family can be found statewide in Illinois.

Family: Cordulegastridae - Cordulegastrid dragonflies are commonly known as spiketails or biddies. “Spiketail” refers to the female’s ovipositor that is easily seen. The body of these dragonflies is long and thin. Body coloration is brown or black with yellow markings. The triangular section in each wing is approximately the same shape and in the same location. The eyes are large and touch at a single point in the middle of the dorsal side of the head.

Spiketails are often found around water in forests.

Family: Corduliidae - Green-eyed skimmers are the dragonflies of this family. The body is usually black or some metallic shade and rarely has light marks. As the common name suggests, the eyes of the adult are bright green. Most of the species have clear wings or clear wings with only a small, dark spot, but there are exceptions. The female does not have an ovipositor.

Adults are most often encountered around aquatic habitats without a current, such as ponds and swamps.

The female does not have an ovipositor.

These species are found around streams and large lakes. They generally do not hover.
