Very good article! 41.204.106.25 ( talk) 06:20, 29 July 2009 (UTC)
This behaviour is not strictly limited to females eating males. Some species of marine parasite exhibit the reverse behaviour [1] 202.151.29.124 01:27, 13 April 2007 (UTC)
"Evidence for male complicity in their own cannibalism is anecdotal and has not been borne out by experimental and behavioral research. "
That was a section of article, allegedly supported by the following source:
"Despite demonstrable male complicity in A. aemula and L. hasselti, and the adaptive significance of sexual cannibalism in L. hasselti, it is unlikely that adaptive male complicity represents a general model for the evolution of sexual cannibalism, because of the prevalence of premating sexual cannibalism."
Emphasis added, because the phrase "demonstrable male complicity" is a strong contradiction to what this wiki page says. —Preceding unsigned comment added by 75.73.32.46 ( talk) 04:09, 26 July 2009 (UTC)
This wiki page suggests that males eating females during mating is always abnormal :
"On rare occasion, these roles are reversed.[1][2] While there are some species in which sexual cannibalism is normal, the aforementioned reversal of roles is abnormal in all."
But source [2] ( http://www.bioone.org/doi/abs/10.1651/C-2343 ) seems to suggest that with Ichthyoxenus fushanensis both male-eating-female and female-eating-male are practised without being abnormal (The abstract is short and quick to read for confirmation) :
" Rather, both types of cannibalism may be regarded as the result of competition between paired individuals"
Otherwise its a very interesting article (sufficiently interesting for me to notice a difference between it and the source), thankyou.

Many oddities occurs within species that pose no evolutionary benefit. What is the function of male-pattern baldness? It's just there, because of some mutation that never threatened the survival of our species; and thus was never ousted from the DNA pool. As far as some species are concerned, it's probably just as insignificant to devour their males during reproduction. 70.153.124.225 ( talk) 05:26, 27 March 2010 (UTC)
Sexual cannibalism is a special case of cannibalism in which a female kills and consumes a male of the same species before, during, or after copulation. I was just wondering how a female could kill and consume a male before copulation. If the male has been killed and consumed how can copulation occur after this event? In invertibrates I can imagine part of the male being eaten first then copulation then death caused by the initial wound? Even this said I think rewording could be good, the first sentence still stands out as being not posible. Carlwev ( talk) 05:51, 22 June 2012 (UTC)

There is plagiarism in this article. A lot of content is copy pasted from http://ib.berkeley.edu/courses/ib160/past_papers/suttle.html.
I suggest a strict reedition of the article or the original authors will be warned. — Preceding unsigned comment added by 24.201.138.156 ( talk • contribs)
I've noticed while making some recent changes to this article that it mentions sexual cannibalism being prevalent across many orders of insects yet the only insect mentioned in this article is the praying mantis. And the fact that the praying mantis is the only example given in this article also adds more confusion, because does that mean either most insects or insects which are primarily carnivorous? Because I doubt herbivorous insects such as butterflies or weevils would engage in sexual cannibalism (I can understand animals such as arachnids and crustaceans, as the former is primarily carnivorous while the former is omnivorous, but there are many herbivorous insects around). Definitely something which needs more clarification in this article later on and perhaps there should be a few more examples of insect species/orders mentioned here alongside the praying mantis.
