Recently the appearance of a new pokémon, Cutiefly, has brought a lot of attention to the real world species in which it is based. So why not bring it to Friday Fellow so that you may know a little more about this creature? Its name is Anastoechus nitidulus, which I will call here “cute bee fly”, as most people find it very cute.
The cute bee fly belongs to the family of flies called Bombyliidae and commonly known as bee flies. The name comes from the fact that adults usually feed on nectar and polen, just like bees, and some of them are important pollinators.
Unfortunately, just as many species, the cute bee fly may be very popular among laypeople and you find a lot of nice pictures of it on the web, just as the one above. However, scientifically, very little is known about its ecology.
Nevertheless, on thing is certain: despite its cuteness, it is not such a lovely creature. Its adult life flying from flower to flower hides a dark and evil past. During their period as larvae, bee flies are predators or parasitoids, meaning that they grow up by eating another animal alive, from inside out, in something that is certainly very horrible for the poor victim.
In the case of the cute bee fly, things are not that terrible. They feed on the egg-pods of grasshoppers, especially of the genus Calliptamus, so we can say that they are parasitoids of eggs instead of adults, but then you realize that eggs have embryos, so they are actually baby-eaters!
