The aptly named diabolical ironclad beetle (Phloeodes diabolicus) has an exoskeleton so strong, it can survive being pecked by birds and even run over by cars. When early entomologists tried to mount them as specimens, BBC News explained, that exoskeleton would snap or bend their pins.

Food safety and environmental groups Wednesday condemned a decision by officials in Florida to approve the release of 750 million genetically modified mosquitoes, a pilot project aimed at reducing the spread of mosquito-borne diseases.

Bees are responsible for pollinating key crops like apples, and their decline now threatens crop yields. Pikist

Without bees, future generations may not be able to identify with adages like, "An apple a day keeps the doctor away."

Crop yields for key crops like apples, cherries and blueberries are down across the U.S. because of a lack of bees in agricultural areas, a Rutgers University-led study published Wednesday in The Royal Society found. This could have "serious ramifications" for global food security, reported The Guardian.

Editor's note: According to recent press reports, two Asian giant hornets – a species not known to occur in North America – were found in northwest Washington state in late 2019, and a hornet colony was found and eliminated in British Columbia. Now scientists are trying to determine whether more of these large predatory insects are present in the region. Entomologist Akito Kawahara explains why headlines referring to "murder hornets" are misleading.
