July 6, 2019 – Summertime here in northern Illinois is the time we find a variety of dragonflies that are using the wetlands and prairies. Healthy ecosystems provide a food source and a breeding habitat for a number of types of dragonflies like the beautiful amber colored Halloween pennant, Eastern pondhawk, Great blue skimmer, Red-mantled saddlebags, Black saddlebags, and many more. One of the largest dragonflies is the Common green darner that is actually a dragonfly that migrates over 400 miles to lay their eggs in the calm backwaters, ditches, and ponds of our area. A research paper published December 19th, 2018 “Tracking dragons: stable isotopes reveal the annual cycle of a long-distance migratory insect” (Hallworth et al), explains “We demonstrate that darners undertake complex long-distance annual migrations governed largely by temperature that involve at least three generations.” It seem unlike birds that travel back and forth and repeat their migration for a number of years, the green darner’s migration requires three generations to complete a full cycle of going north, back south, and back north. Due to their small size, dragonflies can easily go unnoticed by most, but slowing down, especially in those ideal habitats of prairies and wet areas, a fascinating window to some stunning colors and beautiful detail can open to the patient observer with such a variety of these little flying gems.
July 22, 2018 – The dragonfly has had its’ place in the myth and symbolism of humans for thousands of years, both good and evil has manifested in the folklore and the art of both prehistoric and modern humans. From the primitive cave paintings to the Art Nouveau dragonfly pendants there is no denying that their beauty is an inspiration. Their evolution began over 300 million years ago, as some fossil records show amazing giant dragonfly like insects with wingspans of over two feet. But from a different path millions of years ago our modern dragonfly evolved. The modern dragonfly is much smaller, the largest dragonfly in North America is the Giant Green Darner of the Southwest that has a wingspan of around five inches. Here in Illinois we have the Common Green Darner that looks similar to the Giant Green Darner but it is a little smaller with a wingspan of a little over three inches. The photo shows the Common Green Darner clinging to a corn stalk leaf where many others were feeding along a grassy road in rural Iroquois county.
June 26, 2018 – Along the uncut rural roadsides and in the meadows where the butterflies go, along the creeks and over the sparkling waters of ponds, the delightful summer air is in motion with dragonflies of many shapes and sizes with a variety of color patterns. Halloween Pennants, Common Whitetails, Eastern Pondhawks, Widow Skimmers and other species like the Twelve Spotted Skimmer which is found throughout the U.S. and southern Canada is shown in the photo perched on a dried weed in Iroquois county. Mostly unnoticed or ignored, dragonflies can only really be appreciated for their unique beauty and color patterns when seen through binoculars or a camera zoom.
