Interesting Fact:

“Bumblebees (Bombus lucorum), a species that is often parasitized by invidious little conopid flies that insert their larva in the bee’s abdomen. Once infected, the bumblebee dies in about twelve days, and the parasitical flies pupate until their emergence the following summer. What’s interesting about this, however, is that parasitized bumblebees essentially go off to commit suicide by abandoning their colony and spending their remaining days alone in far-away flower meadows. In doing so, these infected bumblebees are leading the flies away from nonparasitized kin, increasing inclusive fitness by protecting the colony from infestation.”
