== General description ==
Should the first picture in this section really be of a damselfly? I feel like this may lead to confusion, even if the purpose of the image is to point out the differences. Would it make sense to replace this picture with, say, a picture comparing a damselfly with a dragonfly, instead of a picture of a damselfly by itself?

:: Well, it's good of you to take the time to consider the article, thank you. Your suggestion is feasible and articles do occasionally do that kind of thing. However, there are many reasons for thinking that the image is appropriate and well positioned. Firstly, readers will already have encountered the four earlier pictures of dragonflies in various states. The damselfly is clearly captioned, is a close relative, and the adjacent text makes the distinction, as does the caption itself. The adjacent text benefits from being illustrated in this way, and indeed would be less easy to visualise without an illustration. More dragonflies, including an illustration of their anatomy next to the description of dragonfly anatomy, immediately follow. I hope I may be allowed to suggest as gently as possible that, since in fact you were not personally confused, we have so far a total of zero persons who actually found it difficult. We know that many readers consult only the lead, or indeed only the first sentence or two; they see an image of a dragonfly up there, so they don't risk any confusion. By the time they get down here, they have already seen several dragonflies and seven pairs of wings outspread at rest. Perhaps we shouldn't be too concerned.

The terms 'nymph' and 'naiad' are mostly in North American and casual usage (e.g. your 'oders'!). Tillyard (1917) and Corbet (1962, 1980, 1999) press for use of the general term 'larva', and this usage is followed by most Odonata biologists.
The picture of the larva feeding on a tadpole is of a dytiscid (water beetle). Check the coxa, single-segmented tarsi, shape of legs, body, and the terminal appendages. There are lots of photos about of aeshnid larvae feeding on tadpoles and fish.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/123.211.75.176|123.211.75.176]] ([[User talk:123.211.75.176|talk]]) 12:11, 6 August 2016 (UTC)</small> <!--Autosigned by SineBot-->

== Male insects do not have a penis ==

Nice primer on these aerial master critters, but I’ve noticed something about male reproductive anatomy as presented in the "general description" section, paragraph 4. This states that the male has a penis and clasper on its second abdominal segment, in apparent contradiction to the anatomy diagram, which shows the clasper on the ''tenth'' and last segment. No penis is indicated, nor do I think insects have penises. According to North Carolina State U. entomologists, the organ male insects use to deposit sperm is called an ''aedeagus''. My guess is that it would also be on the tenth segment, near the clasper. A probable flaw in the article which deserves a look-see.

:Good point, there is indeed some error. There is no penis or clasper on the second abdominal segment. [[User:Shyamal|Shyamal]] ([[User talk:Shyamal|talk]]) 13:44, 20 November 2018 (UTC)
::Dragonfly reproductive anatomy is much different from other insects. It was already in the reference used, Needham, J.G. (1975). A Manual of the Dragonflies of North America, page 20-21.

== Size?  Weight? ==

It seems strange that this article says absolutely nothing about how big dragonflies are, except for the precise size of an extinct distant relative.  I'm kind of curious about the ones that eat frogs. [[Special:Contributions/2601:C6:4100:F980:EC69:B969:D1CE:CBE8|2601:C6:4100:F980:EC69:B969:D1CE:CBE8]] ([[User talk:2601:C6:4100:F980:EC69:B969:D1CE:CBE8|talk]]) 04:17, 7 September 2021 (UTC)

== Water Mites ==

Strange Thing Happened The Other Day; A Dragonfly Flew Up To Me And Tacitly Asked Me To Remove Two Orange Mites, One From Off It's Leg And The Other From Under It's Wing. I Found A Small Twig, Then It Crawled Up On My Hand And Let Me Remove The Mites. Is That Odd? [[User:VerifyTruth927|VerifyTruth927]] ([[User talk:VerifyTruth927|talk]]) 16:35, 20 August 2022 (UTC)

In My Opinion, Dragonflies Are More Intelligent Than People Often Assume. [[User:VerifyTruth927|VerifyTruth927]] ([[User talk:VerifyTruth927|talk]]) 18:42, 20 August 2022 (UTC)

==Is this correct?==
The article claims the internal gills in the nymphs are "located around the fourth and fifth abdominal segments". I have not found this information anywhere else on the net (or anything else about where they are located). The illustration used in the book that's quoted does not seem to support it.

== Something about Winged “Bugs” Including Dragonflies  ==

I thought winged insects were supposed to only have one pair of wings and that dragonflies were therefore another type of invertebrate out of having two pairs of wings. [[User:Cbsteffen|Cbsteffen]] ([[User talk:Cbsteffen|talk]]) 15:56, 2 May 2023 (UTC)
:{{u|Cbsteffen}}, I'm not sure where you read/heard this information, but it's not correct. Many insects have two pairs of wings: bees, dragonflies, butterflies and moths, etc. etc. [[User:MeegsC|MeegsC]] ([[User talk:MeegsC|talk]]) 16:07, 2 May 2023 (UTC)
::Microsoft Rewards seemed to say that. I must have misread something about the classification of dragonflies. [[User:Cbsteffen|Cbsteffen]] ([[User talk:Cbsteffen|talk]]) 05:18, 3 May 2023 (UTC)
:In fact all the winged insect have two pairs of wings, one pair reduced secondarily (into halteres) in the [[Diptera|flies]] and the [[strepsiptera]]. [[User:Shyamal|Shyamal]] ([[User talk:Shyamal|talk]]) 03:34, 3 May 2023 (UTC)
