Welcome to Daily Bitachon , we're now in our Sha'ar Bechina going through the wonders of creation, and we're in the world of insects, and today we're going to talk about the dragonfly. The dragonfly is the most successful predator on earth with a hunting success rate of over 95%. It doesn't chase prey; it intercepts it by calculating where the mosquito will be in the future. It's a famous hockey saying, I skate to where the puck is going to be, not where it has been. Well, the dragonfly made that up. How does that work? Its eyes contain 30,000 individual facets, giving a nearly 360-degree view, and it can move each of its four wings independently. The dragonfly's nervous system calculates the prey's velocity and trajectory instantly. The results, it meets its prey at a future point in space, similar to how a quarterback throws a ball to a running receiver. As we said, each one of its four wings is powered by its own set of muscles, which allows the dragonfly to flap the front and back wings out of sync, even flap one wing while the other stays still. And therefore can hover, fly backwards, and make high-G turns that would snap the wings of an ordinary bird. Again, God gave this tremendous wisdom to this little creature. Another famous one, the firefly. It is a master of bioluminescent efficiency, outperforming every light bulb ever made by man. A firefly's light is 100% efficient. It produces cold light with zero heat loss. It utilizes a chemical reaction between luciferin and oxygen, regulated by an enzyme called luciferase. The purpose of this color is to create a visual light language for mating, identification, obviously without the risk of the insect's body catching fire. And as we said, it's 100% efficient. In a standard light bulb, 90% of the energy is wasted as heat; in a firefly, 0% is wasted. The chemical reaction is so perfectly tuned that every bit of energy is converted into a photon of light. This allows the insects to glow brightly for hours without draining energy it reserves or overheating its internal organs. One more for today, the water strider. The water strider is a physicist that treats the surface of a pond like a solid trampoline. It glides across the water at speeds of 100 body lengths per second without ever breaking the surface. Its legs are covered in thousands of microscopic hairs that trap air bubbles. So it never actually touches the water; it touches a layer of air. And these hairs are grooved to trap air, which creates a cushion that prevents the water from wetting the leg. The bird-like light frame stays suspended on the water's surface tension, using the dimples in the water to push off like a sprinter off a starting block. So this way, it can exploit a habitat where it's safe from land predators and can detect the vibration of drowning insects. So as we're seeing, every single one of these insects is given a wondrous tool in order for its survival specifically in its habitat. And again, wonders of wonders of our Creator.
