Everyone calm down. This is just viral advertising by Blizzard for Starcraft II. Zerg power!
(Here’s a related link for your viewing pleasure. Not as gross as the OP unfortunately: Infected Snails)
I guess that explains it.
Thanks psychonaut. The only info I had been able to find online mentioned regular eggs as a stage of the fly’s life.
Thanks Terrifel. I used an Olympus e410, 14-42mm with a 10x macro adapter.
There’s more where that came from! Discounting inflected forms, we have overconservative, overvivid, vivisective, and my personal favourite, vulvovaginitis.
The tse-tse fly is also viviparous. Search “viviparous flies” in Google.
RedSwing: your fly is not an ordinary housefly… I mean it’s a different species.
While it doesn’t seem to be what’s happening here, some parasites can leave their host functioning just fine even with large loads of them. If for whatever reason killing or weakening the host is bad for the parasite, then it will tend to evolve to be less harmful. I recall reading of the example of a salamander that tends to have as much as a third of it’s blood composed of a parasite; but the parasite doesn’t hurt or kill the salamander because it only infects other salamanders at the end of the salamander’s life when it breeds.
True, it is not in a parasite’s best interest to be too damaging. If those little maggots had however, been actually consuming their host as I thought they were, that little fly would not have lasted long.
