Freshwater ecologists often group invertebrates based on how they eat. Black fly larvae filter particles out of the water and in one case, they managed to help put a murder behind bars. This time around I'll be chatting about these incredible little organisms that improve water quality and are food chain links between incredibly small morsels and the fish we love to catch.

I'll also be sending some love out to those incredible curators and lovers of books that run independent book stores. On both sides of the Atlantic I have been graciously hosted by independent book stores and I wanted to show my appreciation in this small way.

North Branch Nature Center in Montpelier Vermont will be hosting me on September 26th at 6:30 PM and this event will be co-hosted by Bear Pond Books. We'll talk about my book: Turning Stones: Discovering the Life of Water! You'd all be most welcome!

Macroinvertebrates, or the invertebrates we can see, are sentinels of clean water monitored by professional biologists. They can also be a gateway drug for budding scientists young and young at heart. This episode describes inexpensive equipment for catch-and-release studies of macroinvertebrates in ponds and streams.

This video takes you through the same approaches.

Imagine a worm that enters the body of a different species, and then takes over its brain, altering its behavior to the benefit of the work and to the detriment of the host. Such is the story of the horsehair worm.

In warmer weather, have you ever encountered a cloud of flies buzzing up and down near a water body? Chances are that you have encountered a swarm of midges. This episode gets into the biology of these amazingly diverse little insects. I am also pleased to announce my first book event at Phoenix Books in Burlington Vermont at 7:00PM on Thursday June 6th 2024. Finally, I reveal some secrets of the podcast recording process in my back yard shed.

The episode art is a photograph of a male adult midge with its characteristic feathery antennae. The females have simpler antennae but are none the less incredible products of fine-tuned evolution. The art comes from Wikimedia user WanderingMogwai and is shared under

It is entirely likely that you share your dwelling with some generally innocuous beetles that subsist in corners on dried crumbs, cat hair, or other dried organic materials. But, it can sometimes happen that these beetles reach numbers that can threaten wool carpets or fur coats....or worse still, these insects may consume your insect collection. This episode discusses these fellow travelers.

The episode art pictures a varied carpet beetle, one of many species in the family Dermestidae that we discuss today. The photograph was uploaded to Wikimedia Commons by user Didier Descouens.

What sucks the juice out of many plants, leaves a sticky mess that promotes mold growth, and will lay its eggs ANYWHERE. The answer is the spotted lanternfly, a beautiful insect that hails from East Asia and is spreading from an introduction site near Allentown Pennsylvania. Although it is pretty, it can be destructive in its home away from home.

Scuba divers pump compressed air into or out of jackets to hang neutrally buoyant in the water column. Few insects can manage the same feat and must hang onto to plants or expend energy swimming. But one insect can shunt oxygen in and out of an air bubble to "float" anywhere between the water surface and the pond floor. This same insect turns camouflage on it's head to adapt to its unusual back-stroke approach to swimming. Backswimmers do all of this and are also well equipped with a beak that can get your attention if you mishandle them.

A friend and radio broadcaster in my home town asked me to record something about the process of writing and publishing a book. I suspect that each book develops on a unique trajectory, and mine seems certainly to be unique. It's my first book and so I claim limited expertise on the topic. There were pitfalls, and one major one, but it was nothing I could have avoided. So this podcast is certainly not a how-to, but more of a how-I-did. And when you write your book, I'm sure it will be in a very different way than I did.

Episode art is Adelaide Murphy Tyrol's art on the book cover. The book is available for pre order here:
