“In the natural world, anything that is colored so brightly must be some kind of serious evolutionary badass”*…

There are an estimated 10 quintillion (10,000,000,000,000,000,000) individual insects alive on earth today; they’ve been around for over 350 million years and ihabit nearly every environment, from deserts to snowy mountains. Their total biomass is massive, estimated to be around 70 times more than all humans combined. Often considered pests, only about 3% of species are harmful to humans; the vast majority are crucial for pollination, decomposition, and as food sources for other animals. (More insect data.)

I am incredibly fond of insects. They’re small and usually pretty fast, so it’s rewarding to successfully capture a photo of one. from 2017 to 2023, I was fairly consistent about chasing down bugs and sharing the photos on instagram, but sticking them all in a square grid can only do so much for me (or you). Here, I want to have a little more fun with my photos, and share other bug-related things that I like. There’s a lot! I am not an entomologist, merely a bug fan, so this page in its current state skews more towards the entertaining than the informative, but who knows what it may turn into. Right now there’s an entomology textbook sitting on my coffee table, and plenty of time to read it while the bugs overwinter…

As we creep and crawl, we might spare a thought for a man concerned with “bugs” of a different sort, Joseph Lister (1st Baron Lister, OM, PC, FRS, FRCSE, FRCPGlas, FRCS); he died on this date in 1912. A surgeon, medical scientist, and experimental pathologist, he was a pioneer of antiseptic surgery and preventive healthcare. Just as John Hunter revolutionised the science of surgery, Lister’s revolutionized the craft of surgery.

Lister researched the role of inflammation and tissue perfusion in the healing of wounds, and advanced diagnostic science by analysing specimens using microscopes. But his biggest contributions were a function of his application of Louis Pasteur‘s then-novel germ theory. Lister introduced carbolic acid (modern-day phenol) as a steriliser for surgical instruments, patients’ skins, sutures, surgeons’ hands, and wards, promoting the principle of antiseptics. And he devised strategies to increase the chances of survival after surgery by reducing post-operative infections (e.g., segragating post-op patients from pre-op patients who had germ-riddled wounds).

“The lovely flowers embarrass me, they make me regret I am not a bee”*…

… But then, what would it be like to be a bee? In the tradition of Thomas Nagel (bats), Peter Godfrey-Smith (octopuses), and Kristin Andrews (crabs), Lars Chittka explores…

Understanding the minds of alien life-forms is not easy, but if you relish the challenge, you don’t have to travel to outer space to find it. Alien minds are right here, all around you. You won’t necessarily find them in large-brained mammals—whose psychology is sometimes studied for the sole purpose of finding human-ness in slightly modified form. With insects such as bees, there is no such temptation: neither the societies of bees nor their individual psychology are remotely like those of humans (figure 1.1). Indeed, their perceptual world is so distinct from ours, governed by completely different sense organs, and their lives are ruled by such different priorities, that they might be accurately regarded as aliens from inner space.

Figure 1.1. The strangeness of the bee’s world

Insect societies may look to us like smoothly oiled machines in which the individual plays the part of a mindless cog, but a superficial alien observer might come to the same conclusion about a human society. Over the course of this book, it will be my goal to convince you that each individual bee has a mind—that it has an awareness of the world around it and of its own knowledge, including autobiographical memories; an appreciation of the outcomes of its own actions; and the capacity for basic emotions and intelligence—key ingredients of a mind. And these minds are supported by beautifully elaborate brains. As we will see, insect brains are anything but simple. Compared to a human brain with its 86 billion nerve cells, a bee’s brain may have only about a million. But each one of these cells has a finely branched structure that in complexity may resemble a full-grown oak tree. Each nerve cell can make connections with 10,000 other ones—hence there may be more than a billion such connection points in a bee brain—and each of these connections is at least potentially plastic, alterable by individual experience. These elegantly miniaturized brains are much more than input-output devices; they are biological prediction machines, exploring possibilities. And they are spontaneously active in the absence of any stimulation, even during the night.

To explore what might be inside the mind of a bee, it is helpful to take a first-person bee perspective, and consider which aspects of the world would matter to you, and how. I invite you to picture what it’s like to be a bee. To start, imagine you have an exoskeleton—like a knight’s armor. However, there isn’t any skin underneath: your muscles are directly attached to the armor. You’re all hard shell, soft core. You also have an inbuilt chemical weapon, designed as an injection needle that can kill any animal your size and be extremely painful to animals a thousand times your size—but using it may be the last thing you do, since it can kill you, too. Now imagine what the world looks like from inside the cockpit of a bee.

You have 300o vision, and your eyes process information faster than any human’s. All your nutrition comes from flowers, each of which provides only a tiny meal, so you often have to travel many miles to and between flowers—and you’re up against thousands of competitors to harvest the goodies. The range of colors you can see is broader than a human’s and includes ultraviolet light, as well as sensitivity for the direction in which light waves oscillate. You have sensory superpowers, such as a magnetic compass. You have protrusions on your head, as long as an arm, which can taste, smell, hear, and sense electric fields (figure 1.2). And you can fly. Given all this, what’s in your mind?…

As we buzz, we might spare a thought for a successful entrepreneur whose empire depended on bees (and their capacity to pollinate plants), Washington Atlee Burpee; he died on this date in 1915. A horticulturist, we turned his childhood interest in the selective breeding of poultry, and his passion for research in the genetics of breeding into Burpee Seeds, the world’s largest mail-order seed company.

Tastes like chicken…

Readers struggling with an appropriate response to the U.N.’s recent suggestion that all of us in the developed world should be getting much more of our protein from eating insects will be relieved to know of the brainchild of four London-based graduate students, the Ento Box…

What began as a graduate project has matured over the past two years, with a series of caterings and pop-up restaurants introducing insect-based dishes to new audiences around the U.K. Just before Easter, the founders of Ento (which is a portmanteau of bento box and entomology) served buffalo caterpillars at the Edinburgh Science Festival, the largest event they’ve participated in so far. They want Ento to grow organically–with more supper clubs this year and a restaurant in about 18 months. Slow growth allows them to see firsthand how the food is received, to understand their customers, and to build up good will en route to hitting supermarket shelves in a few years. Before mass consumption of insects can become a first-world reality, you need to fix the perception problem. With a nod to the aesthetics of sushi presentation, that’s precisely what Ento does…

“Sushi was a very inspiring story for us,” says cofounder Julene Aguirre-Bielschowsky, who met her cofounders at the Innovation Design Engineering MA/MSc double masters course at the Royal College of Art and Imperial College London. Aguirre-Bielschowski, who is German but is originally from Mexico, says she and her colleagues were initially met with skepticism from advisors, but she says they found inspiration in a 30-year-old Japanese travel book that advised tourists to beware of “strange Japanese restaurants that serve raw fish.”

If sushi could make fans out of skeptics in just three decades, then why not bugs?…

As we struggle with our chop sticks, we might recall that it was on this date in 1955 that George B. Hansburg of Walker Valley, N.Y. was issued a U.S. patent for his invention of an improved pogo stick (No. 2,793,036).  In the event, while the design was a step forward over earlier incarnation, Hansburg’s 1955 version posed something of a risk to the user’s chin.  He went back to the drawing board and two years later patented something much more like the pogo stick we’ve come to know and love.

“The Creator, if He exists, has an inordinate fondness for beetles”…

J. B. S. Haldane was moved to utter the quote that gives this post its title by his observation that there are more types of beetles than any other form of insect, and more insects than any other kind of animal. Cataloguing beetles, then, is a formidable challenge… But not too daunting for Dr. Udo Schmidt of Selbitz, in Germany.  Dr. Schmidt has photographed and catalogued thousands of them– which readers can find here.

(Dr. Schmidt, something of a taxonomical overachiever, has also photographed and collected thousands of mollusks.)

As we wonder where we left that roach, we might recall that it was on this date in 1871 that the American Museum of Natural History opened to the public in New York City. Organized into a series of exhibits, the Museum’s collection–which had been gathered from the time of the Museum’s founding in 1869– went on view for the first time in the Central Park Arsenal, the Museum’s original home, on the eastern side of Central Park. The cornerstone of the Museum’s first building was laid in Manhattan Square (79th Street and Central Park West), the Museum’s current location, in 1874; but it is obscured from view by the many Museum buildings in the complex that today occupy most of the Square.
