Episode 10: The hidden value of the unwanted pests in your garden
If April showers bring May flowers, then what do May flowers bring? It turns out the answer is insects—and a lot of them. But before you go grabbing a can of heavy pesticide, these tiny creatures might actually be the most important, undervalued workers keeping the entire state of Texas alive.
In this episode of Launchpad, host John Elizondo sits down with Dr. Jessica Beckham, an environmental science and ecology lecturer at the University of Texas at San Antonio. As a dedicated bumblebee enthusiast and researcher, Dr. Beckham’s passion for native ecosystems sheds a vital light on a looming environmental crisis, revealing that pollinators are in steep decline everywhere we find them. Because they operate as essential keystone species, their disappearance could cause entire ecosystems to collapse.
But the conversation goes far deeper than just bees. Dr. Beckham unpacks the fascinating world of entomology, explaining how widely misunderstood insects—from stinger-wielding wasps to "gross" nutrient cyclers like dung beetles and flesh flies—provide a massive environmental service completely for free. Tune in to learn why 86% of Texas agricultural land relies directly on these tiny workers, what terrifying Texas predator hunts tarantulas to feed its larvae, and how you can manage pesky mosquitoes and garden aphids by simply letting nature run its course.
