Dragonfly Days Weekend, May 15-18, Showcases Colorful New Pursuit
Posted by: Larry Bozka on April 19th, 2008
I received this news release several days ago from the good folks at the Texas Parks & Wildlife Department. It brought to mind a macro photo I took last summer of a ruby dragonfly, a beautiful insect that upon close inspection sent me and my good friend, photographer Mark Hall of CoastalPhotos.net, scurrying for our Nikons.
After getting back home from the trip to Lavaca County, I did a little homework and learned that the species we encountered, the Ruby meadowhawk dragonfly (S. rubicundulum) is a common species. When I subsequently discovered that the creatures possess a decided affinity for mosquitoes as preferred menu offerings, I decided that I really like these colorful critters. Just about anything that eats mosquitoes is my buddy. It was not surprising to discover that the spindly, long-legged insects we call “mosquito hawks” are essentially dragonflies as well.
Interesting dragonfly facts: The largest known dragonfly buzzed above the rainforests of the massive collective continent “Pangaea” over 270 million years ago, during the Carboniferous period and had a wingspread of 29 inches. That is one big honkin’ bug.
The Ruby meadowhawk is actually a species of damselfly (a type of insect well known to trout stream fly-fishers who tie various fly patterns to mimic the aquatic stages of the insects’ development. Brook trout apparently like to eat damselflies as much as damselflies like to eat mosquitoes.
Like a magnified version of a house fly, the head of an adult dragonfly is largely comprised of the compound eyes. Being a popular food item for various birds, it’s no wonder that … like wild turkeys … these creatures are built for super-wide-angle vision. The dragonfly’s mouthparts are adapted for biting and for scooping prey from the air as they fly about. The insect’s spindly legs are located on the far-forward portion of its body and enable it to firmly grasp a nesting spot such as a twig (or, in the instance Hall and I encountered, the ball-rounded end of a radio antenna extending from the hood of a Chevy Suburban).
Not surprising to learn, either, was the fact that the Ruby meadowhawk dragonfly is generally tolerant of close observation. Mark and I were both amazed when the insect, after being alerted by our a-bit-too-close photo work, returned to the truck antenna to rest on several subsequent occasions. Wind was no deterrent, either. Its legs, like those of most insects, are incredibly strong in proportion to the size of the creature.
Males like the one Mark and I observed are apparently very territorial creatures, which perhaps explains the dragonfly’s stubborn persistence in staking out and maintaining his location.
If you find any of this even remotely interesting (and forgive me if you don’t, but the older I get, the more I enjoy learning this kind of thing), you will no doubt enjoy the event detailed in the press release that follows. Just think of it this way: Next time you go fishing at your local pond and Junior gets bored, you can always steer him (or

“Allowing free fishing in our state parks serves the dual purpose of reaching out to people who are not traditional fishing license holders by removing barriers to the sport and providing another incentive to visit a state park,” says state parks promotions coordinator Bryan Frazier.
