- The source says
There has been some concern that light pollution from man-made sources (particularly mercury vapor street lights) may deter lunas and other silk moths from mating and have a negative impact on their populations in urban areas
- The page saysNorthern populations from Michigan up have one generation, the Ohio Valley has two, and the south has three.
- The source says
The luna moth is univoltine (one generation) from Michigan northward, bivoltine throughout the Ohio Valley, and trivoltine southward

- The source says
In Louisiana and Florida, adults may be found during every month of the year
- The page saysThe cocoon is spun among the leaves but is not anchored to a twig.
- The source says
The cocoon is spun among the leaves of the deciduous host plants but is not anchored to a twig
- The page saysIt falls to the ground in autumn as the leaves fall
- The source says
they fall to the ground in autumn (Holland 1968) as the leaves fall

- The page saysA big green silk moth whose spinning hindwing tails pull bat attacks off its body, and whose adults do not eat.
- The source says
luna moths (Actias luna) generate an acoustic diversion with spinning hindwing tails to deflect echolocating bat attacks away from their body and toward these nonessential appendages
Note: tagline; adults half claimed below - The page saysSpinning hindwing tails that gave tailed moths a survival advantage of about 47% over tailless ones against big brown bats
- The source says
We pit luna moths against big brown bats (Eptesicus fuscus) and demonstrate a survival advantage of ∼ 47% for moths with tails versus those that had their tails removed.
Note: stats.superpower - The page saysThose tails are decoys.
- The source says
Moth tails lured bat attacks to these wing regions
Note: decoy = lure, the abstract's verb - The page saysResearchers used high-speed infrared video to watch luna moths spin their tails to deflect attacks by echolocating bats
- The source says
Using high-speed infrared videography, we show that luna moths (Actias luna) generate an acoustic diversion with spinning hindwing tails to deflect echolocating bat attacks

Lee & Moss (2016). Can the elongated hindwing tails of fluttering moths serve as false sonar targets to divert bat attacks? The Journal of the Acoustical Society of America.
- The page saysA second study found that the tail echoes are weak compared with those of the wings and body.
- The source says
the results show that the tail echoes are weak and do not dominate the sonar returns, compared to the large, planar wings and the moth body
- The page saysTheir twisted shape, though, creates echoes that persist from every angle, which may make a bat misjudge where the moth is.
- The source says
the distinctive twisted morphology of the tails create persistent echoes across all angles of orientation, which may induce erroneous sonar target localization and disrupt accurate tracking by echolocating bats

How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
