Dragonfly behavior
Hi all - On several occasions I have seen a dragonfly fly close to the
water, tilt its tail part 90 degrees and quickly dip it into the pond a number of times. Even saw this once just using a little water on a lily pad. I'm guessing its either 1)Drinking from the wrong end 2)Decided my pond is his potty 3)Is giving me the finger, but cant fly up side down or 4)Laying eggs or whatever they have? Got any ideas? btw- It has sure been an unexpected treat to get to see a growing number of varieties of colors and shapes of dragonflies. Till now I had barely noticed those oversized flies and at other locations. I think they were mostly blue/black or reddish tinged. I saw one recently that appeared to have landed and and then rotated his wings perpedicular to the ground. This may be common, but not for me. Bill Brister - Austin, Texas |

Dragonfly behavior
Hey Bill, your answer is behind door number four 4)Laying eggs The eggs will hatch, spend the winter in the pond as larva eating up tiny critters, fish fry and tadpoles if you have any. They catch them by ejecting their jaw out from under their bodies and snagging their lunch. In the spring, or late winter for you I expect, they will crawl up out of the pond on a plant stem, split the back of their skin and the dragonfly will emerge, spread its wings, let them dry and then fly off leaving the extoskeleton behind. They are the kewlest bugs. The US military studied them to figure out how they work. They fly in antiphase which is very impressive but I forget exactly what it means. They form a basket with their front legs and scoop up winged insects on the fly, eat them and carry on all with out stopping.

They fly in antiphase which is very impressive but I
forget exactly what it means. Most of the stronger insect fliers have evolved means to link their forewings and hindwings in flight so that each side functions as one flight surface. Dragonflies and damselflies, in contrast, move the two pairs independently, timing the stroke of the hindpair so that they meet the oncoming air before it has been disturbed by the front pair. Physicists would describe them as operating in antiphase.

Dragonflies are becoming my favorite part of the 'pond experience' as my herd has grown to a few dozen of varying colors. There are some huge scarlet ones that put on quite a show in the evening while I relax with a soothing beverage. |

I like that they buzz around and mostly come to roost back at the same place - makes photographing them easier. I spend lots of time standing in my pond, camera focused on a rush. I'm also not embarrassed to say that I've rescued dragonfly nymphs from my skimmer! San Diego Joe 4,000 - 5,000 Gallons.

Dragonfly behavior
This is just too much!.. Yesterday I watched my 16 year old son while he
watched the two newest dragonflies at our new pond. He was clearly fascinated with them and before he left to go and be fascinated with his girlfriend he asked, "Mom, what do you know about dragonflies? They fly funny!" He has always had his head in the air, loves anything about anything that flies, and has his hopes set on flying for the navy someday. Thanks to you all I can tell him that dragonflies do indeed fly funny, if he didn't already look it up for himself last night.. wrote in message ...

Yes, arent they just too cool. I have a couple of those huge scarlet ones
and also a very large electric lime one, but it has most of its color on the section behind the head rather than the tail segment. Got any idea about what the scarlet one is. If I got a clear pic(havent) but was going to ask the group. When I tried to look it up the closest I found was a Scarlet Bog I believe, but it was from Australia. We're not that south. It looked just like it though. Brite Red long and very broad appendage part, rusty on section behind the head. Bill "grubber" wrote in message ... "Newbie Bill" wrote in message . ..

Its dragonfly during the day. Mosquitos do the same thing at night.

Dragonfly behavior
Here is some info I dug up from this site:
http://powell.colgate.edu/wda/biting_dragonflies.htm Do Dragonflies Bite? A). "Can you tell me if dragonflies bite?" The answer to this question has three parts: (i) "Do dragonflies bite?" YES, dragonflies bite, because that's how they capture their food. They have impressive, sharply pointed mandibles that chomp down on the smaller insects they catch. (ii) "Do dragonflies bite people?" YES, if you catch one and hold it in your hand and carelessly allow its mandibles to reach your skin, it will bite as hard as it can in self defense. Very few dragonflies can even break the skin, but some of the big ones can do so and may induce an "ouch". They're certainly no danger to you, as the biggest dragonfly has a relatively small bite. A word of warning though: if, for some educational reason, you plan to let a dragonfly bite you, make sure you don't suddenly pull back, as you'll probably pull its head off and this is not a good example to present your audience! (iii) "Do dragonflies bite people spontaneously?" A big resounding NO. A dragonfly would never land on someone and bite. B. There is a second question: "Do dragonflies sting?" The simple answer to this is NO - they have no 'sting' as such. BUT there have been a number of accounts of egg-laying dragonflies that, when interrupted, continued the operation into the flesh or clothing of examining odonatists. Such actions could well be the origins of the many "old wives tales" pertaining to stinging dragonflies, and could also provide the answer as to why odonates have the names of 'Horse- stingers' and 'Devil's Darning Needles'. These names, and others like them, are part of dragonfly folk-lore in many parts of the world. Philip Corbet (author of Dragonflies: Behaviour and Ecology of Odonata) drew our attention to the definition of a dragonfly in Samuel Johnson's Dictionary (1755) as "a fierce stinging fly": possibly the result of a painful experience? C. Lastly: "And what about larvae?" Again basically, despite their ferocious appearance, dragonfly larvae do not harm people. However, late-instar larvae of larger species can use their mandibles to take a nip at an intrusive odonatist's finger to give a noticeable poke. Cases have also been reported of loosely held larvae 'stinging' a researcher by turning its abdomen from side to side and inserting the sharply-pointed lateral spines into the intruder's flesh. The main thing to remember is that all animals do what they can to protect themselves and that odonates are no exception. Although even minor blood-letting is highly unlikely to be encountered, it is advisable to handle captured dragonflies with care. If one receives a nip, it is only too easy to react by involuntarily releasing the insect - and, of course, "the one that got away" is always the rarest and most-desired!
