Biologists discover caterpillars are able to sense electrostatic fields generated by predators
[The researchers tested specimens of cinnabar moth, the scarce vapourer moth and the European peacock butterfly] for the ability to sense and react to an artificially generated electrostatic field that matched the output of that generated by a wasp. [All] three species responded very clearly to an electrostatic charge—some flailed their bodies, others coiled in a defensive posture.

Brunneria borealis is the only praying mantis species that always reproduces asexually. Every individual across its U.S. range is female, and a new study finds little genetic variation among them, pointing to a relatively recent introduction. Researchers posit that a single female mantis that could reproduce without a male may be the origin for the entire population of the species in North America.

Are insects drawn to light? New research shows it’s confusion, not fatal attraction
Rather than being attracted to light, researchers believe that artificial lights at night may actually scramble flying insects' innate navigational systems, causing them to flutter in confusion around porch lamps, street lights and other artificial beacons.

Mapping bedbugs: S Korean blockchain engineer fights infestation with data
His fear of bedbugs drove him to create an interactive map that shows the approximate locations of reported infestations across the country, as well as real-time news stories on the issue. The site now receives as many as 50,000 visitors a day, up from around 40 when Kang launched it.
