• Maybe you could mention some of the earliest flying insects in the fossil record, like Delitzschala bitterfeldensis or Rhyniognatha?   User:Dunkleosteus77 |push to talk  13:19, 7 July 2021 (UTC)

• Good idea, done.

• "a small movement of the wing base downward, lifts the wing itself upward" why the comma?   User:Dunkleosteus77 |push to talk  13:19, 7 July 2021 (UTC)

• Edited.

• "dorsal longitudinal muscles" this isn't really a vocab word, it's just the muscles on the dorsal surface which run longitudinally (a good gloss would be "the muscles running across the back"), and "tergosternal" is just the muscle running from the tergum to the sternum   User:Dunkleosteus77 |push to talk  13:19, 7 July 2021 (UTC)

• Edited both.

• In Leading edge vortex, are all these debates fought by a bunch of people or do models just get periodically revised/superseded by a few people?   User:Dunkleosteus77 |push to talk  13:19, 7 July 2021 (UTC)

• It seems that now the main mechanisms have been elucidated, they have remained stable.

Because it might be better to say "proposed by entomologist Harley Hudson" or something along those lines when introducing each hypothesis   User:Dunkleosteus77 |push to talk  22:37, 7 July 2021 (UTC)

Added names and citations for different effects.

• I wouldn't consider 2003 to be that recent as it's been nearly 20 years   User:Dunkleosteus77 |push to talk  13:19, 7 July 2021 (UTC)

• Removed.

• I'm worried you didn't gloss enough fluid dynamics terms. Like "a Reynolds number that is typical of insect flight" you don't explain what a high or low number means or what's considered high or low, and what it typically is for insects is far removed   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Added gloss and ref. An idea of the range of values is given a little further on.

• "viscous effects are much more important to the smaller insects, although the flow is still laminar, even in the largest fliers" if the R number is as high as 10⁴, how can the flow still be laminar? Are you sure it's not 10³?   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• The value is correct; edited the text.

• "low Reynolds number flight" it'd be a lot easier to gloss Reynolds number and talk in terms of laminar and turbulent flow   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Edited.

• "as the wings need separate and rotate"   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Fixed.

• par 3 and 4 in Clap and fling are missing refs at the end   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Removed, someone else's ORish accretions.

• "far field flow" I've only seen near and far field used in reference to electromagnetic fields. Lift should be normal (perpendicular) to airflow   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Fixed.

• link incompressible flow   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Done.

• "The Mach number, or speed while moving through air" velocity relative to the speed of sound   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Fixed.

• "R_e=uc/ν" specify which u and c   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Removed the equation.

• "They include wind tunnel experiments of a tethered locust and a tethered fly, and free hovering flight of a fruit fly" every experiment includes these?   User:Dunkleosteus77 |push to talk  10:08, 8 July 2021 (UTC)

• Edited.

• The first par of Hovering says it's a super complex process and then proceeds to just describe an insect fluttering its wing so fast that it doesn't fall. The entire thing is summed up in the last sentence   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Edited.

• "If the insect flaps its wings at a slow rate, the time interval during which the lifting force is zero is longer, and therefore the insect falls farther than if its wings were beating rapidly" worded more complicated than it actually is. Seems pretty obvious, the faster it flutters, the less it will fall   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Edited.

• Is it supposed to be 2W_d instead of 2Wd?   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)
• Either gloss erg on first mention or just use more widely recognizable joules   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Yes.

• "After, the energy has to go somewhere" this implies a closed system. The energy was expended to create lift, that's why the insect needs to expend more energy to lift the wings again   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Rewritten.

• In text, you should put spaces around the = sign for readability   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Done several.

• "the velocity varies sinusoidally along the wing path" could we replace "varies sinusoidally" with "oscillates"?   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Done, with gloss.

• You don't have to do this, but I've only ever seen Young's elastic modulus denoted as E, so maybe you can refer to the potential energy using the more standard U   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Let's leave it for now.

• What is dyn?   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Dyne. Goes with Erg.

• "The stored energy in the two wings is 36 erg" you should clarify again here that this is for a bee-sized insect   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Done.

• "which render these taxa as 'functionally dipterous' " it seems like you copied this from wing coupling, so you should replace dipterous with two-winged   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Done, clearly better.

• The jugum is a general term for any projection that confers to the joining of two elements   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Edited.

• "except the male of one species of hesperiid" you should just say what the species is   User:Dunkleosteus77 |push to talk  21:21, 8 July 2021 (UTC)

• Simplified.

More

• It'd make more sense to put a picture of a fossil flying insect in the Evolution section   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Moved the hoverfly to Hovering, indeed.
• Added a fossil image.

• What is Polyneoptera?   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Linked and glossed.

• "The hypothesis with perhaps the strongest evidence is that which stems from the adaptation of endites and exites" you should start by saying "According to Trueman"   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Edited.

• italicizing pod doesn't make it any less confusing.

• Edited.

• Also, it'd help to put a picture of a biramous leg   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Done.

• "This mutation was reinterpreted as strong evidence" you already said this in the first sentence   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Removed the repetition.

• You should be attributing all the hypotheses in Evolution because it sounds like this is just 1 or 2 people talking   User:Dunkleosteus77 |push to talk  08:01, 10 July 2021 (UTC)

• Done.
