Twelve-spotted Skimmer (Libellula pulchella)

Also known as the ten-spot skimmer, the twelve-spotted skimmer is a common species of skimmer (Libellulidae) that occurs in southern Canada, the United States, and Mexico. Like other dragonflies this species is a predator and will feed on other flying insects. Libellula pulchella is primarily active during the summer and often inhabits ponds, lakes, streams, and other bodies of water.

This image is a good example of how people uncritically taking pictures from Wikipedia / Wikimedia Commons can lead to problems. What problems, you ask?

This image looks like a reputable scientific illustration. It has been replicated on hundreds of educational websites. But those wings are not dragonfly wings at all. They are honey bee wings. Dragonflies and bees are two of the most distantly related groups of insects: their wings are nothing alike.

Endangered dragonflies, raised in captivity over several years, being released in Illinois

by Regina Garcia Cano

Federally endangered dragonflies that have been raised in a laboratory over the past several years are being released at a forest preserve this week in Illinois, where scientists believe they’ll be a good match with the small population still there.

The Hine’s emerald dragonflies, which for decades were believed to be extinct, were carefully raised at the University of South Dakota over the past four to five years after eggs were collected from a dragonfly in southwestern Wisconsin. Three out of the 20 dragonflies that could be released have already been freed so far this week at a forest preserve near Chicago. No more than 320 of the insects remain in Illinois…

Macro close up (dorsal view) of one of North America’s most common and widespread dragonflies, the Common Green Darner, Anax junius (Odonata - Aeshnidae).

Anax junius is a large insect (6.8 - 8.4 cm length, 9 - 11.4 cm wingspan), with yellowish-green face and large, dark green eyes, which meet on the top of the head. Both the male and female have a distinctive “bull’s-eye” mark on the top of the forehead, consisting of a black or brown spot ringed with blue and yellow. The abdomen is blue.

The Common green darner is widespread across North America, occurring in Alaska and southern Canada, throughout the United States, and south to Mexico, as well as sometimes further south in Central America. It is also found on Bermuda and in the Caribbean.

This migratory species has also occasionally been recorded outside of its normal range, in Hawaii, northeast Asia, the United Kingdom and France.
