Book Review: Bugged Delivers a Mixed Bag

Well over a year ago, someone at St. Martin's Press contacted me by e-mail asking me to review David MacNeal's latest effort, Bugged: The Insects Who Rule the World and the People Obsessed with Them (2017, St. Martin's Press, 297 pp). They would hardly take no for an answer, sent me an advance uncorrected page proof, and so finally, here is my assessment, colored by the circumstances of my receipt of the book, my lack of familiarity with MacNeal's previous works, and my personal biases, which I will reveal honestly.

First, my sincerest compliments to the author for his most thorough research, his diligent reading of numerous books and scientific papers, and in-person visits with the human subjects highlighted in Bugged. Whatever shortcomings the book may have, the foundation it was built on is as solid as they come. Additionally, I can say that in my opinion the book gets markedly better the farther the reader gets into it. Unfortunately, I found the first one-third to two-thirds of the book to be an exercise in the author's ego, perhaps due to my own peculiar style that I prefer to write in, and the approach to the subject that I would rather read.

The chapters reflect an overall theme that I am personally averse to: that in order to validate their existence, all non-human organisms must prove they have an economic value to humanity.

MacNeal may simply be trying too hard in the first chapters to convince the reader that he is edgy, funny, irreverent, intellectual, and jet-setting. It comes off as self-centered in my opinion, and aimed more toward those who value shock-and-awe prose. I prefer that an author remove themselves as much as possible from non-fiction, save for memoirs and autobiographies. I personally try to get out of the way of the story when I am writing myself, unless my direct experience is the story. I see no need for profanity ever, not because I am opposed to it, but because I think it can be a distraction if not a detraction from the rest of the words used. I do not try and paint myself as intellectually superior by throwing around words and phrases from foreign languages.

The choice of categories that define the chapters was predictable: Insect specimens as novel merchandise, social insects as a parallel to human societies, insect and spider sex lives, insects as disease-carriers, the pest control industry, insects in forensic science, insects and other arthropods as the source of inventions and advancement of technology, insects as live entertainment in Asia, entomophagy (intentional human consumption of insects as food), and honey bees as perhaps the most important of all insects (to mankind).

The chapters reflect an overall theme that I am personally averse to: that in order to validate their existence, all non-human organisms must prove they have an economic value to humanity. Maybe MacNeal recognizes this and is planning a sequel that will visit topics like endangered insects and the people working to save them, the economic impact of "ecological services" provided by insects and related invertebrates, and the myriad of citizen science projects available for his readers to participate in and become active contributors to science instead of passively entertained by his books. MacNeal does give a nod to ecological services, as almost literally a footnote (another aspect of books that I find distracting and mildly irritating); and he lists a few conservation organizations in the acknowledgements at the end of the book.

The bottom line is that I am glad the book was written, but I would have preferred that someone else had written it. If you enjoy this brand of storytelling that focuses on both insects and people, you may be better off reading works by Richard Conniff or Sue Hubbell.

Does MacNeal succeed in recruiting a new generation of entomology-appreciators? Hard to say. I think it takes actual in-person engagement with scientists to achieve that, and I hope that Bugged encourages readers to take that next, crucial step toward a better understanding of invertebrates in general, and an appreciation of those people, not the eccentrics you presume them to be, who make a living in the science of entomology.

More Beetles from Bones

Last week I wrote about a few beetle species that I recovered from nearly dry bones here in Colorado Springs. I now have an update, plus additional species found in carrion on a recent trip to a private ranch northeast of Pueblo. It is interesting to note the succession of carrion beetle fauna over time; and the differences in diversity depending on whether the carcass is a large mammal, small mammal, bird, herp (reptiles and amphibians), or fish.

I went back to the bones I found earlier, and discovered some changes as of April 18. I spotted another Northern Carrion Beetle, Thanatophilus lapponicus, before it quickly disappeared, and more dermestids that I previously identified as Dermestes marmoratus. However, a different, smaller species was now more abundant.

Hide and Tallow Beetle, Dermestes talpinus?

I have decided I cannot readily conclude what species are involved here. Twelve species of Dermestes are recorded from Colorado, many of which look nearly identical to each other. The smaller species present on the bones appears to be the Hide and Tallow Beetle, D. talpinus. It is covered in gold or coppery scales on the pronotum (top of thorax), and silvery scales on the elytra (wing covers).

I also found a single specimen of yet another species that is possibly the Fringed Dermestid, D. frischii.

Dermestes frischii?

My wife and I travelled to Chico Basin Ranch on Monday, April 21, mostly seeking spring migrants of the feathered variety. This is a sprawling, working ranch that straddles El Paso and Pueblo Counties, and is managed for both livestock and native wildlife.

Unfortunately, one of the first birds we came across was a deceased Bobwhite quail. Turning it over revealed a shocking diversity of beetle life.

Rove beetles in the family Staphylinidae are predatory, and the ones that visit carrion feed mostly on fly maggots. They are easily recognized by the shortened elytra (wing covers), and are perhaps reminiscent of earwigs.

Hairy Rove Beetle, Creophilus maxillosus

The Hairy Rove Beetle, Creophilus maxillosus, is enormous by staphylinid standards, measuring 11-23 millimeters. These insects fly well, but quickly dig themselves out of sight when uncovered.

Rove beetle, Philonthus politus

Another rove beetle species, Philonthus politus, was also present. It is much smaller, about 10 millimeters. Special thanks to Philip Howe and Max Barclay for suggesting the genus, and Adam Brunke for volunteering the species. Facebook interest groups are a wonderful thing.

Sexton beetle, Nicrophorus sp.

Two species of the family Silphidae were also under the bird carcass: Thanatophilus lapponicus again, and one of the sexton beetles, Nicrophorus sp. Sexton beetles, also known as burying beetles, are big (11-22 mm or so), stocky, and strong. They often work in pairs to dig under the corpse of a small animal, sinking it into the ground. They then chew the carcass into a literal “meatball,” and the female then deposits a small number of eggs in a crater atop the food ball. She’ll chew up small bits of meat and feed them to her larval offspring, cleaning the food of mold and other potential contaminants in her spare time.

Clown beetle, Saprinus lugens

Clown beetles in the family Histeridae are small, spherical, highly-polished insects that play dead or dig when disturbed. They are predatory on other small insects found in carrion, dung, and other unsavory mediums. This one is Saprinus lugens, a common and widespread species measuring 5-8 mm. Thanks to Alexey Tishechkin for the species identification.

Male Scooped Scarab, Onthophagus hecate

Many dung beetles will also visit carrion, such as the little “Scooped Scarab,” Onthophagus hecate. Males have a broad, forked horn projecting over their heads from the top of the thorax. They battle each other for the right to mate with a female. At only 6-9 millimeters, O. hecate is one of the smaller dung beetles.

Hide beetle, Trox sonorae

Last but not least, were cryptic “hide beetles,” Trox sonorae, in the family Trogidae. They are closely allied to scarab beetles. Trogids are rough in texture, and usually so caked in debris as to be nearly unrecognizable as insects. They also play dead so convincingly as to be easily dismissed as living creatures. They freeze in a random, rigid posture when disturbed. This species is only 8-11 millimeters in size, which only makes it even harder to spot. Trox consume dried skin, feathers, and other material when carcasses are in the last stages of decay.

Silphid carrion beetle larva

Dermestes larva

Later in the day, Heidi and I came across the remains of a large livestock mammal, and virtually none of the beetles found on the dead quail were on this much larger vertebrate. Instead, it was carrion beetle larvae, dermestid larvae and adults, and Red-legged Ham Beetles, Necrobia rufipes. There are three common species of Necrobia, all in the family Cleridae. While most clerids are predators, Necrobia adults and larvae actually do feed on carrion, cured meats, and other dried animal products. They can be pests in museums and taxidermy businesses. Ham beetles are about 4-7 mm., but are a lovely metallic blue. They glint in the sunlight as they run over the surface of a dried corpse.

Red-legged Ham Beetle, Necrobia rufipes

Forensic entomology is the study of insects that infest dead bodies. Blow flies (family Calliphoridae) play the most prominent role in crime scene investigations because they can help ascertain the time of death. The life cycle of flies progresses in a predictable fashion, faster at higher temperatures, slower at cooler temperatures. By collecting adults, larvae, and pupae, a criminalist can determine at what time a body was first visited by ovipositing female flies.

Obviously, other insects play a critical role in decomposition as well, and beetles are chief among them. Those of you with strong stomachs may want to examine animal carcasses you come across, as the insects found there can usually be found nowhere else. Just remember to pack the hand sanitizer.
