Traumatic insemination, seen here in the
bedbugCimex lectularius, is the insertion of sperm into the female by breaking through the carapace of the abdomen and injecting the sperm inside. This makes the male's reproduction more efficient; however, the threat of infection and necessity of healing decreases the female's life expectancy. Traumatic insemination is also found in some other invertebrate species, including some
nematodes,
flies, and
leaf bugs.Edit1 Gaussian blur on background to reduce artifacts
Reason
A stunning illustration: You can see the carapace cracking.

comment I wish the focus were on the point of insertion.

Given the difficulty of the image - the bedbugs are not going to stay still for you - I think that it's surprisingly good.

Support. Good heavens, we've sunk from bug porn to bug rape. Highly encyclopedic though. May I step on them?

Comment You know, I've just been looking closer, and noticed there's some JPEG artefacting. It seems to be almost entirely in the background, but be aware.

Support educational value is much more important to me that some background jpeg artifacts. --

Conditional support. Too bad about the focus, but there's not much that can be done about that. There is however a dust particle on the sensor or the mirror, just under the thorax of the male. Full support with bells if you remove that. --

Weak support for good EV and hard to capture. --

Support- the important part is in focus. I wonder if she's in pain?

Probably not -- In the majority of examples of invertebrate nociception noted above, there seems to be little, if any, evidence that the animals' responses persist in anything akin to the manner described for mammals. As Eisemann et al. (1984) have described in a review of the "biological evidence" concerning pain in insects, "No example is known to us of an insect showing protective behavior towards injured parts, such as by limping after leg injury or declining to feed or mate because of general abdominal injuries. On the contrary, our experience has been that insects will continue with normal activities even after severe injury or removal of body parts."Raul654 (

Support Edit1: Definitely worthy.
