Nature Snippets Declan McCabe

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:

We have dramatically changed our climate. It's easy to consider that the change is slight. After all, who can remember what our climate was like back in the 70s? Back when it was "normal"? But consider this, roughly 60% of the US population had not even been born until the 1980s. So, our childhood recollections of "normal" weather occurred when climate change was already well underway. Scientists call this phenomenon the "shifting baseline" - what we each consider baseline conditions is very different from what a pre-industrial baseline might look like. This episode examines long-term data sets to explore how climate has affected important parts of the New England culture like ice fishing, lilac flowering, and maple sugaring.



The episode art is from the Joe's Pond Association website. It shows a concrete block perched on a wooden pallet on the frozen pond. "When the ice breaks, the pallet will fall, and down will come cinder block".....unplugging a clock to establish the precise moment of ice out!

Ladybugs, Ladybirds, or Lady beetles are familiar to all in art and in reality. These little munchers of aphids and other garden insects are common in many habitats. If the supply of soft-bodied insects on your cabbages dwindles, the adults will fly off to other plants in your garden and elsewhere. Because lady beetles have been collected and sold for as biological control agents, species have been moved from place to place and even between continents. This episode covers such topics and also addresses efforts to document rare native species and even farm them for reintroduction into their former habitats.
