• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

Crop circles are large geometric patterns that appear in fields of crops, usually corn (because cornfields are creepy), and are created by flattening the stalks in such a way that each individual one remains undamaged. They are usually presented as being supernatural in origin, with the most common explanation being that they were created by extraterrestrials, although the reasons behind why aliens visiting Earth would want to do such a thing varies.

In fiction, the question of who's going to pay for the vandalized crops never seems to arise.



  • In a Duck comic, Donald Duck and Daisy visit Ireland and discover Crop Circles are created by dancing fairies.
  • In a Zits strip, Pierce thinks aliens are leaving crop circles in his hair in an attempt to communicate with him. It turns out just to be bed head.
  • One X-Files comic has Mulder go to a Crop Circle in progress and discovers a kid with a board and a flashlight flattening the stalks. The kid gets away, and may not have actually existed.


  • The movie Signs features a few of these, as it's a movie about aliens.
    • Parodied in Scary Movie 3. The aliens forgo tracing intricate symbols and simply draw a huge arrow with the words "ATTACK HERE".


  • In Lords and Ladies, the impending visitation of the elves causes crop circles to spontaneously generate in everything from an herb garden to a handful of seeds sprouting in a damp cloth.
    • And lets not forget the Dean's scalp.
  • In Martians in Maggody, the appearance of crop circles in moonshiner Raz Buchanon's field draws a horde of UFO fanatics to the little Arkansas town, eager to photograph (for $10 a head, payable to a grinning Raz) this "inexplicable" phenomenon.

Live Action Television

  • Dark Skies: they build a crop circle to try to lure the aliens into landing, so they could capture them. (Trivia: this episode came out very shortly after the guys who claimed to have started the crop circle phenomenon revealed themselves as hoaxers.)
  • In the episode "Vanished" of NCIS the team investigates crop circles and discovers one was caused by a helicopter and the others by the murderers attempting to cover up their crime.
  • In an episode of Drop the Dead Donkey Damien is in the newsroom when Dave takes a phone call, covers the mouthpiece with his hand and shouts across to him, "It's the farmer on the phone, wants to know how big you want him to make the crop circles."
  • In the Doctor Who episode "Let's Kill Hitler", Amy and Rory contact the Doctor by making a crop circle of his name when he wasn't answering his phone.


  • The outer cover of Led Zeppelin's Box Set shows the shadow of a zeppelin passing over an elaborate set of crop circles, although on closer inspection the "cornfield" in which the circles have been cut looks suspiciously like a carpet.

Real Life

  • Crop Circles are usually made by farmers or others out to prank people. They take a board with a string, and stand on the board, moving it by the string, so that it flattens the cornstalks without breaking them. Or something like that. They also lead to millions of conspiracy nuts.
    • Crop circles' frequency of appearance closely follows the change in value of the crops.

Video Games

  • In Spore, during the Space Stage, you can use Crop Circles to "communicate" with more primitive (meaning "not in space yet") species. There doesn't seem to be any real game effect, but they look cool.
  • Crop circles can appear in farm fields in Sim City 3000 when UFO attacks occur.

Western Animation

  • One episode of Invader Zim has Dib job-shadowing a paranormal investigator who takes him out to investigate some crop circles. Dib quickly points out that they're caused by a cow which is rolling back and forth across the field.
  • In Rocko's Modern Life, Heffer is working as a groundskeeper in a golf course and he keeps making crop circles with his lawn mower. At the end of the episode, aliens look at the circles and ask "Who keeps writing this stuff?"
  • On the first episode of South Park, a report on alien sightings features a crop circle formation in the exact likeness of Cartman, who has been implanted with an alien probe.

 Cartman: Hey! That looks just like... Tom Selleck.

  • The Pixar Short "Unidentified Flying Mater" had Mator create crop circles shaped like tires.
