I saw an incredibly disturbing "Stories From The ER" about a BABY who had bot flies. The poor dad was beside himself. The mom had skipped out and he did not have the money to put the baby in day care, so he took her with him to his job at a farm/barn. Needless to say, it was not good.
The good that came from this was the mom's parents got involved again and were able to start helping him with watching the baby.
Poor thing! I saw an extraction video once posted by a guy who does anthropological field work in South America. He had all of his friends over and they had a big party for the "birth" of the botfly. It turns out there were actually two. It was easily the most horrifying thing I've ever seen.
This is the blog it's from. Don't click on the video if you don't want to; but his other entries are fascinating and awesome.
I don't mind big hairy spiders, weirdly. I hate the spindly smaller ones more.
The toads don't bug me, but holy hell, botflies do.
My cousin and his wife went to Costa Rica for their honeymoon this past fall. He came back with a botfly in his ankle. His new bride will never be the same as he squeezed the botfly out and it flew across the room into her lap. There are many more details, all of them equally as terrifying.
