Frass Happens

Arachnophobia is a common human fear, but where does it come from? Are we born with it? And if so, why? In this episode, Katie not only untangles a web of myths about spiders, but she also spins a tale about the nature of fear itself! Whether you are on Team Spider or Team Scream, we hope that you’ll join us for Episode 9 as we delve into the intriguing (and controversial!) world of spiders, confronting our own feelings about our eight-legged neighbors along the way.

Insects and other invertebrates have stoked our curiosity since we were children. For many of us, these creepy crawlies were beloved childhood pets who taught us how to become responsible caretakers and opened up our realm to the wonders and joys associated with the miniature worlds around us. In today’s episode, Casey explains the natural history of two favorite invertebrates that many of us kept as kids in the 90’s and early 2000’s: Mexican jumping beans and sea monkeys! So put down the Tomagotchi, hop on your Razor scooter, and let’s explore the secret lives of these nostalgic creatures.

We just can’t get enough of the ocean! In today’s episode, Casey brings us back in time to 1999 to discuss the Long Island Sound lobster die-off. This event just so happened to follow heavy, recurrent pesticide use in New York City in response to the first US-based West Nile Virus outbreak. So, were pesticides to blame for this massive die-off in our beloved crustaceans?! To find out, join us for Episode 6 as we delve into this buttery tale!

Did you know that there are approximately 20,000 species of bees?! In this episode, Casey & Katie take us into the wonderful, diverse world of native bees, and help to dispel some myths surrounding bees at the same time! They discuss native bee diversity, the pros and cons of bee hotels, why you shouldn't get a honey bee hive to "save the bees," and how you can support your local pollinators in your own backyard!

In Part Two, Casey and Katie share the stories of three endangered insects: The American Burying Beetle, the Karner Blue Butterfly, and the Rusty Patched Bumble Bee. At the end, we discuss what folks can do to protect endangered and otherwise threatened species. And, luckily, there’s a lot we can do! Including a little bit of mischief-making…
