* This happens in quite a few chapters of ''Manga/PetShopOfHorrors''. One of the most explicit is in the first volume, when a customer buys a beautiful bird which, to her, looks like a gorgeous, winged man. She buys a female of the species when she worries that he's lonely and follows the Count's instructions to leave him alone for a period of time, but gives in and checks in on them one day early. As it turns out, the birds reproduce by the pregnant female eating the male and, by looking in a day early, the girl was "treated" to the sight of her beloved pet's still-living chewed-off head.

* In the ''ComicBook/{{New 52}}'' version of ''ComicBook/WonderWoman'', the Amazons of Themyscira sustain their population by kidnapping men, having sex with them, then killing them. Oh, and if the babies are male, they're sold into slavery. Needless to say, fans were [[https://www.tor.com/2012/04/04/wonder-woman-comics-and-the-violation-of-the-amazons/ not]] [[https://www.themarysue.com/wonder-woman-7/ amused]]. Due the outcry, this was retconned away with ''ComicBook/DCRebirth''.

* Naturally, the [[http://en.wikipedia.org/wiki/Latrodectus black widow spider]] is notorious for this. That's how the BlackWidow Trope got its name. In reality, the Black Widow spider dosen't do this. When an adventurer discovered the Black Widow it was in the process of eating another spider.

* This [[http://www.geekscape.net/how-dc-comics-forced-one-lifelong-wonder-woman-fan-to-quit-buying-her-comic appears]] in issue 7 of the initial ''ComicBook/{{New 52}}'' run of ''ComicBook/WonderWoman''.

* Occurs with the H'nemthe, characters from ''Franchise/StarWars'', who believe that a male killed after mating in this way would receive the ultimate spiritual reward by going on to the netherworld as spiritual guardian for his offspring, meaning that they didn't resist the certain death that would result from copulation. [[http://starwars.wikia.com/wiki/Feltipern_Trevagg Felitipern Trevagg]] is an example of a male character who was part of this ritual.

* A variant in ''Series/{{Supernatural}}'': The Amazons are superficially human, [[OneGenderRace all-female]] monsters who have children by human men; the children are [[ExpressDelivery born within a day of conception]], [[RapidAging age to adulthood in three days]], and [[{{Patricide}} kill their fathers]] as a RiteOfPassage. [[spoiler:And that's how Dean -- briefly -- becomes a father.]]

* ''Series/BuffyTheVampireSlayer'': The MonsterOfTheWeek in "Teacher's Pet" is a She-Mantis which preys on male virgins: mating with them to fertilise her eggs and then killing them.

*** "What are you? A bigot or something?" "No. But obviously you've never met an Arnasian before. After they finish, they eat their mate."

Referring to the trope of the female becoming pregnant and then killing her mate, often in the act of copulation. A sub-trope that is part of various tropes, including the {{Black Widow}}, {{Out With a Bang}} and possibly {{Someone To Remember Him By}} tropes.

For obvious reasons (outside of a MisterSeahorse situation) this trope is AlwaysFemale.

* ''WesternAnimation/KungFuPanda2'': Master Mantis says he never had Daddy issues because his mother bit his father's head. He also claims to be looking forward to the day he has a similar demise.

* This is believed to happen with skeleton shrimps: - after mating, the female [[http://www.chesapeakebay.net/fieldguide/critter/skeleton_shrimp injects her partner with venom]].
* Also happens with [[http://factsanddetails.com/world.php?itemid=1591 scorpions]].
* Also known to happen with [[http://en.wikipedia.org/wiki/Praying_mantis#Reproduction_and_life_history praying mantises]] and various species of spider, e.g. the [[http://en.wikipedia.org/wiki/Redback_spider#Reproduction redback spider]], which actively participates in the process.

* Doing this is the whole MO of Sil from ''Film/{{Species}}'', seeing as her one goal is to reproduce, which she does by seducing as many men as possible in order to do so. And given [[EvilIsSexy how stunning she looks in her usual human form]] and [[TheVamp how shamelessly she flaunts her sexuality]], it's rather easy for her to lure men to bed - which ultimately leads them to their doom, unfortunately, as she kills them after mating or at least tries to. (It seems to be more out of instinct than malevolence, however.)

* The Taresians of ''Series/StarTrekVoyager'' are a OneGenderRace of females that mate with other humanoid species by implanting viruses in them that turn them into male Taresians, believing that there are long-lost children driver with the desire to return home. The mating process (a male is given three females as his wives) is deadly to the male, as they end up dying after mating with her wives.

* It also appears in a ''TheIncredibleHercules'' comic (the story told from #121-125). Amadeus Cho has an interest in [[http://en.wikipedia.org/wiki/Delphyne_Gorgon Delphyne Gorgon]], but she tells him that killing after mating is the custom of the women of her race.

* This appears in one ''WonderWoman'' [[http://www.geekscape.net/how-dc-comics-forced-one-lifelong-wonder-woman-fan-to-quit-buying-her-comic comic.]]

* [[InvaderZim Zim]] does this to Dib in the fanfiction ''[[http://www.fanfiction.net/s/3608043/1/Dib-Reborn Dib Reborn'']]. [[SpoilerTitle as you would have guessed from the title]], Dib was reincarnated as Zim's son as a result.
