Female Callosobruchus maculatus mate when they are thirsty: resource-rich ejaculates as mating effort in a beetleDon't tell me you would pass up that tantalizing title if you found it on the newsstand! But if you still find it dry and academic, you can always turn to some friendly science blogger to pre-digest it for you: Jake Young adds good background with a video so you can see what bruchid beetles are, while Mo the Neurophilosopher offers the truly scary photo of male genitalia in these beetles.
Its all "about nuptial gifts (basically, females will trade sex for drinks)" as pondering pikaia puts it, although it seems to me these females have a rather rougher bargain than that - just look at that penis!
Ain't evolution cool?
