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.

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.

Not all roaches are filthy. The Madagascar hissing cockroach actually makes a pretty sweet pet, thanks to the hungry mites that serve as its cleaning crew.

As the weather starts to warm and cold days give way to balmier, sunny days, one rite of spring returns every year, just like spring flowers: cockroaches.

Most people run to buy a can of bug spray or to call the exterminator when they see the scurrying little insects in their kitchens or outside their homes.

But not all roaches are pests. Some are pets – like the Madagascar hissing cockroach.
They can be bought at pet stores or online for $5 or less. They don’t bite and don’t carry diseases. They are also much larger than the run-of-the-mill roach, with adults averaging about 3 inches long. They live up to five years. They are slow-moving and mellow – kind of like an old tabby cat. But with antennae. And an appetite for fresh vegetables.

--- Why do the cockroaches hiss?
They’ll hiss when they’re sounding an alarm or startled, trying to attract a mate or protecting their territory from another male.

--- Are the mites harmful to the cockroaches?
No – they actually help prolong the cockroaches’ lives.

--- What happens to the mites if its host cockroach dies?
The mites will mate, give birth to their young and feed on the same cockroach their entire lives – so they’ll usually die within a few days after the cockroach dies, too, and not seek a new home.

It's an all-out brawl for prime beach real estate! These Caribbean crabs will tear each other limb from limb to get the best burrow. Luckily, they molt and regrow lost legs in a matter of weeks, and live to fight another day.

On the sand-dune beaches where they live, male blackback land crabs do constant battle over territory. The stakes are high: If one of these baby-faced crabs secures a winning spot, he can invite a mate into his den, six or seven feet beneath the surface.

With all this roughhousing, more than feelings get hurt. The male crabs inevitably lose limbs and damage their shells in constant dust-ups. Luckily, like many other arthropods, a group that includes insects and spiders, these crabs can release a leg or claw voluntarily if threatened. It’s not unusual to see animals in the field missing two or three walking legs.

The limbs regrow at the next molt, which is typically once a year for an adult. When a molt cycle begins, tiny limb buds form where a leg or a claw has been lost. Over the next six to eight weeks, the buds enlarge while the crab reabsorbs calcium from its old shell and secretes a new, paper-thin one underneath.

In the last hour of the cycle, the crab gulps air to create enough internal pressure to pop open the top of its shell, called the carapace. As the crab pushes it way out, the same internal pressure helps uncoil the new legs. The replacement shell thickens and hardens, and the crab eats the old shell.

--- Are blackback land crabs edible?

Yes, but they’re not as popular as the major food species like Dungeness and King crab.

--- Where do blackback land crabs live?

They live throughout the Caribbean islands.

--- Does it hurt when they lose legs?

Hard to say, but they do have an internal mechanism for releasing limbs cleanly that prevents loss of blood.

Ultravox - Hymn 1983

Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give me all the storybook told me
The faith and the glory
till my kingdom comes.

And they said that in our time
all that's good will fall from grace.
Even saints would turn their face
in our time.
And they told us that in our days
Different words said in different ways
Have other meanings from he who says
in our time:

Give us this day all that you showed me -
The power and the glory
till my kingdom come.
Give me all the storybook told me
The faith and the glory
till my kingdom comes.

And they said that in our time
we would reap from their legacy
We would learn from what they had seen
in our time.
And they told us that in our days
We would know what was high on high
We would follow and not defy
in our time.

Give us this day
