Welcome to Daily Bitachon, we are now in our Sha'ar HaBechina series, going through the different types of creatures. We started with the fish, and now we move on to the creeping creatures and insects. They all possess a specific design and form; while birds utilize hollow bones for flight, insects utilize an external armor that provides structural integrity while remaining nearly weightless. The Engineering of the Exoskeleton This exoskeleton is made of chitin, a fibrous substance that is incredibly durable yet flexible. This design provides a massive surface area for muscle attachment, giving insects superhuman strength relative to their size. An ant can carry 50 times its body weight because its external frame distributes the load far more efficiently than an internal skeleton would. This is something very interesting—and sorry to get gory—but that is why when you step on a cockroach, you hear a "crunch." Its bone is on the outside, not the inside. Furthermore, the exoskeleton is coated in a microscopic layer of wax, which prevents the insect from drying out, allowing it to survive in harsh, arid environments where other creatures would perish from dehydration. One significant limitation of an exoskeleton is that it cannot grow along with the animal because it is a rigid shell. Eventually, the animal becomes too big for its armor. To grow, the animal must undergo the process of molting, where it secretes enzymes to loosen the old shell, crawls out of it, and waits for a new, larger exoskeleton—formed underneath—to harden. During this time, the animal is soft and highly vulnerable to predators. Many insects, such as ants, beetles, bees, and grasshoppers, go through this molting, as do spiders, scorpions, crabs, lobsters, centipedes, and millipedes. The Divine Purpose of the Purposeful Let's pause on this for a moment. Midrash Tehillim 18:12 records an episode where Eliyahu HaNavi met the great Tana, Rav Nehorai, and asked him: "Why did God create these crawling creatures?" Rav Nehorai answered: "Because when Hashem sees that the people are sinning, He looks down and says, 'Why am I keeping these people going? They are sinners; there is no purpose for them.' But then God looks at the sheratzim , these crawling creatures, and says, 'I am keeping these creeping creatures alive and they seemingly have no purpose. The Jewish people might be sinning now, but eventually they will do teshuvah , so I should surely keep them in the world until they turn around and something special comes of them.'" In this way, the sheratzim cause Hashem to have mercy and patience with the Jewish people. The Chida writes that this adds special weight to the Torah's prohibition against eating insects. If a Jew eats an insect, the insect provides nutrition, thus negating the claim that insects have no purpose. This, in turn, would dismantle Hashem's argument for maintaining the sinning Jewish people in the world. Ironically, insects serve a vital role in Hashem's plan precisely as the epitome of a creature that seems to have no purpose. They are what He points to when He needs to find merit for His erring nation. In Perek Shira , the song of the sheratzim is: "Let Israel exalt in its Maker, let the children of Tzion rejoice in their King." This adds even more impact to the mercy God has on these insects—that He provided them with this exoskeleton, a layer of wax, and the ability to molt. Advanced Sensory Systems Many insects also possess a 360-degree camera. Unlike the human eye with a single lens, many insects have eyes with tens of thousands of hexagonal lenses, providing an unbelievable panoramic view. Another fascinating detail is the way their eyes process motion. We see fast motion as a continuous blur, but a fly sees the world in slow motion. That is why it is so difficult to swat a fly; to the fly, your hand is moving in slow, predictable intervals. Look how God is protecting even the fly! Finally, insects fly differently than birds. While birds have nerve impulses that tell muscles to beat, many insects use a single nerve impulse to trigger a vibration that causes the wings to beat hundreds of times a second. This is just a brief opening to the general topic of insects before we dive deeper.
