From Deep Look:

Females of one firefly group, the genus Photuris, have learned to copy other fireflies’ flashes to attract the males of those species. When one arrives, she pounces, first sucking his blood, then devouring his insides...

Firefly light is biochemical. But fireflies like the Big Dippers do much more with chemistry than just make light. They can mix together an array of other compounds, including invisible pheromones for mating, and others called lucibufagins (“loosa-BOOF-ajins”) that ward off predators like spiders and birds.

At some point, the Photuris “femme fatale” fireflies lost the ability to make their own lucibufagins. So instead of chemistry, these bigger, stronger fireflies became adept at imitation, and evolved to turn into insect vampires to take these valuable compounds from other fireflies to boost their own defenses.

A family of three (including a 7 year old girl) on a British Airways overnight from Vancouver to London spotted bedbugs crawling on their seats and alerted the crew, but the crew said the flight was sold out and wouldn't move them, so they spent 9 hours getting gnawed by bedbugs, arriving with their skin "absolutely covered" in bites.

For years, entomologist Brandon Hopkins has argued for the establishment of a germplasm repository for cryopreservation of honey bee semen. Unfortunately, bee semen us very hard to collect and even harder to preserve, but Hopkins found better ways to extract and store their genetic material. Read the rest

Larry Murdock just returned a library book that he checked out from the Linton, Indiana Public Library in 1956, when he was just 8 years old. The book is "Moths of the Limberlost." Murdock is now a Purdue University professor of entomology who specializes in the study of moths. He said the book turned up in a box.

"(Returning) it was the right thing to do," he said. "Maybe after all those years there are kids out there who might get some benefit" from the book.

Murdock paid a $436.44 fine.

In 2013, Gregory Sutton from the University of Bristol published an important paper demonstrating that bumblebees can sense electricity (his experiment trained bees to associate current in fake flowers with nutrients, and showed that bees preferentially sought out electrified flowers), but now how they sensed it.

The resurgence of the bed bug caught modern civilization flatfooted: an ancient pestilence dating back to the Pharoahs, gone for two generations, has returned with a vengeance, infesting fancy hotels and slums alike, lining our streets with mattresses spraypainted with the warning BEDBUGS. Infested, science writer Brooke Borel's natural history of the bed bug, looks at the bug's insurgency as a scientific, cultural, and economic phenomenon, and will leave you itching with delight.
