Mammalian moms aren’t the only ones to deliver babies and feed them milk. Tsetse flies, the insects best known for transmitting sleeping sickness, do it too.
A researcher at the University of California, Davis is trying to understand in detail the unusual way in which these flies reproduce in order to find new ways to combat the disease, which has a crippling effect on a huge swath of Africa.
When it’s time to give birth, a female tsetse fly takes less than a minute to push out a squiggly yellowish larva almost as big as itself. The first time he watched a larva emerge from its mother, UC Davis medical entomologist Geoff Attardo was reminded of a clown car.
“There’s too much coming out of it to be able to fit inside,” he recalled thinking. “The fact that they can do it eight times in their lifetime is kind of amazing to me.”
Tsetse flies live four to five months and deliver those eight offspring one at a time. While the larva is growing inside them, they feed it milk. This reproductive strategy is extremely rare in the insect world, where survival usually depends on laying hundreds or thousands of eggs.
--- What is sleeping sickness?
Tsetse flies, which are only found in Africa, feed exclusively on the blood of humans and other domestic and wild animals. As they feed, they can transmit microscopic parasites called trypanosomes, which cause sleeping sickness in humans and a version of the disease known as nagana in cattle and other livestock. Sleeping sickness is also known as human African trypanosomiasis.
--- What are the symptoms of sleeping sickness?
The disease starts with fatigue, anemia and headaches. It is treatable with medication, but if trypanosomes invade the central nervous system they can cause sleep disruptions and hallucinations and eventually make patients fall into a coma and die.

Torterra Grey8
Despite looking like a head, they’re actually located at the back of the larva, which used them to breathe while growing inside its mother. The larva continues to breathe through the lobes as it develops underground.

Awwwww that larva is adorable! How can u say that?!
These videos frequently remind me why I'm happy I live in Northern Ireland, and will never encounter the vast number of parasites and big bloody bugs.
In Europe we already eradicated most of our species which explains why we don't have nearly as much parasites as we should have.
Glad to be in Belfast

Sounds good man!! Northern Ireland is amazing. Greetings from Sardinia

"To guard them from parasites"
Your telling me that is not a parasite
No,parasites live with their host most of their lives till eventually one of them dies.
The fly is a parasitoid.
@@jamesestrella5911 but not a parasite.
Even parasites get parasites in a cruel twist of irony. It just keeps going down further and further. These creatures are called "Hyper parasites" such as parasitoid wasp larvae, they parasitize caterpillars but are at risk of being parasitized themselves by other wasps.
Parasites that feed on parasites.
I came to hear how they managed to pronounce tsetse fly. I wasn't disappointed. Bloody hilarious 🤣🤣
tetsey flies 😭
Larva looks kinda cute tbh.
Are we just gonna ignore the fact that someone sacrificed their skin for the fly to feed on them :
Nah they do that all the time. Maybe its even the same person everytime
Nope. That's just cold of these guys to let them do that. They should've done it on something else :P
I care for ALL bugs
Omg!!!! I scrolled until I found a comment that showed the same thing I was thinking! 😣😩🤦🏾♀️🤔

Also Deep Look: *proceeds to have a human arm for a tsetse to suck blood from*
sleep and get paid, that's look like win-win situation to me
A lab fly might by disease free after years of research = many generations of an isolated population.
@@coyowolf4609 I see this as an absolute win!
They can test flies to see if they are carring anything. Probably kills them in the process, but you can still test offspring and isolate the parents.
The disease is caused by protozoan parasites, the African trypanosomes. If the flies is not infected, their bite is harmless (well, it will cause a big rash though). Labs working on trypanosomes/tsetse interactions usually use cattle-specific parasites to avoid any risk of human contamination.
