Welcome to our daily Bitachon . We're in Shaar Habechina , looking into the wonders of creation, and we're talking about insects now. There's a certain wasp that's called a jewel wasp that is almost like a neurosurgeon. It turns a cockroach into a zombie to serve as a living, fresh food source for its larvae. How does this happen? It delivers a precise sting directly into the cockroach's brain, targeting the exact cluster of neurons that controls the escape reflex. So this disables the host's will to move while keeping it alive and walking so it could be led to a burrow like a dog on a leash. Now, there's more wisdom than just sticking the needle in, because it has to be a probe. As the stinger enters the cockroach's head, the wasps use sensors on the tip to feel for the brain, and once it's in there, it has to find a certain part of the brain and gives a dose of venom that targets the dopamine receptors inside of the cockroach's brain. And therefore it loses its motivation to run. It can still walk but it can't run. And actually the wasp is saving energy by walking its prey home rather than carrying it. And this is not the only creature that God gave this ability to, so to say, hijack another animal and turn it into a zombie. This is really a subject on its own. There are many, many examples of this. We'll give you one other example. There's a type of hairworm which can grow up to four times longer than its cricket hosts. It begins life as a microscopic larva that the cricket accidentally consumes while drinking water. Once inside the cricket's body, the worm develops over several weeks, eventually occupying most of the host's body cavity. The infected cricket continues to behave normally for most of this period. But as the worm nears maturity, something sinister occurs. The parasite begins producing proteins that affect the cricket's nervous system, compelling the normal insect that is used to being on the ground to seek out water sources. When the cricket reaches a pond, stream, or even a swimming pool, it plunges in despite being unable to swim. Once in the water, the mature worm bursts from the cricket's body and begins its aquatic reproductive phase. The cricket, now fatally injured and waterlogged, typically drowns. Science has discovered that these worms can alter their host's behavior so precisely that infected crickets are three times more likely to jump into water than healthy ones, even when presented with the same environmental cues. So this is again a wonder of wonders. In order to keep this hairworm continuing to reproduce, Hashem gave it the ability. Again, it's got to get back to the water. It starts in the water. The cricket drinks it as a larva in the water. It grows in the cricket and then brings the cricket back to the water for it to once again start its reproductive system. So we have two zombie examples where one creature takes over the brain of the other one. And there are many such examples, but this is just a little flavor of what God can do. We will now talk about the flea. Everyone heard of the statement: if you lie down with dogs, you get up with fleas. What are fleas? There are actually 2,500 species of these small flightless insects that live as external parasites on mammals and birds. Fleas live by ingesting the blood of their hosts. They lack wings as we said, they are flightless insects. So if they lack wings, how do they move around? We'll get to their hind legs that are very well adapted for jumping. We'll get there in a minute. But they have special skin-piercing parts in their mouth and they're great at sucking blood. They carry disease and they're responsible for a famous disease called the bubonic plague. It was responsible for the Black Death that swept through Asia and Europe and Africa in the 14th century and killed an estimated 50 million people. This is all the different plagues that happened over the years. So what makes the flea so deadly is you can't swat him. He just moves so fast. He jumps 200 times its body length at tremendous speed. Now, how do they jump? What gives him the ability? Muscles alone couldn't do it. So what does it do? In the flea's knee joint is a pad of resilin, which is an elastic protein. The flea cocks its legs and locks them with a latch, which compresses this resilin pad. When the latch is released, the energy is put into this jump in a fraction millisecond creating a launch speed that no muscle could achieve. So, again, this flea needs blood. He's got to move around. So and he's got to be swat free. He's got to be unstoppable to get around. And that's the flea, this common flea that's on dogs and all over the place. He has to have this special design to make him successful. And we continue with
