Warning: This video is not for the squeamish
When Harvard University entomologist Piotr Naskrecki was bitten by mosquitoes during a visit to Belize, he received more than an itchy patch of skin.
While sucking on his blood, the mosquitoes deposited botfly eggs.
"I realised that some of my mosquito bites were not really healing. I also noticed that something was living in them," Naskrecki says in the above video.
The eggs soon hatched under the skin due to the heat of the human body.
Naskrecki removed a small botfly from under his skin using tweezers, but decided to leave the two remaining botflies buried under the surface because he had never had the opportunity to see an adult botfly up close.
"I also thought that being a male, this was my only chance to produce another living, breathing being out of my flesh and blood," he says.
It took two months for the larvae under Naskrecki's skin to reach the stage when they were ready to emerge without assistance.
He says the process took about 40 minutes, and was not particularly painful.
Even so, we'll be avoiding adult botflies at all costs.
Eight Bugs You Don't Know You're Eating
Aphids(01 of08)
Open Image ModalIf you thought aphids were only a threat to your tulips and roses, think again. The number of whole aphids that the FDA deems permissible varies from vegetable to vegetable. On the low end, you can expect about 30 whole aphids/100 grams in Brussels sprouts and about 60 of the little buggers in frozen broccoli. (credit:Shutterstock)

Open Image ModalThere's a good chance you've seen a fruit fly before, buzzing around a fruit basket or a wine glass left out too long. There's also a good chance that you've been ingesting these flies with your fruit juice, since there's about five flies in every 1 cup of juice. (credit:Shutterstock)
Cowpea Curculio(06 of08)

Caterpillars(07 of08)
Open Image ModalYou'd think it would be hard to miss out on something like a caterpillar in your food, but just because you don't see it doesn't mean it isn't there. Such is the case with spinach, which can be dotted with caterpillar larvae and larval fragments. (credit:Shutterstock)
Corn Ear Worm(08 of08)
Open Image ModalThe next time you're shucking corn, keep an eye out for the corn ear worm, which fortunately doesn't go for the kernel, but rather, the silk in the husk. You'll also want to double-check canned corn since these worms tend to leave traces of their skin and larvae where ever they go.
