Rumors of a ‘homicide hornet’ apocalypse could have been exaggerated

As if 2020 wanted an additional catastrophe, the yr additionally introduced us “homicide hornets.”

When two Asian large hornets (Vespa mandarinia) had been noticed in Washington and close by British Columbia in Might, information headlines heralded their “arrival” with a wierd mixture of horror and glee. By no means thoughts that the invaders had been noticed within the state the yr earlier than; by some means it felt that they belonged in 2020.

Science Information has tried to calm the thrill with details. For one, the invasion shouldn’t be as apocalyptic as some headlines have instructed, life sciences author Susan Milius reported (SN: 7/4/20 & 7/18/20, p. 14). Not solely is that this not the primary massive hornet to invade the USA, the predatory bugs hunt for honey­bees, not folks. And the hornets should not precisely taking on. Scientists have mounted an intensive effort to eradicate them — officers in Washington discovered and destroyed their first nest in October — and a map launched this yr means that swaths of difficult habitat would possibly make it exhausting for the hornets to brush throughout America (SN: 11/7/20, p. 12).

That hasn’t stopped folks everywhere in the nation from pondering they’ve discovered one. “Instantly, ignored native wasp and hornet species … hanging round in corners of individuals’s backyards for millennia grow to be the themes of panic-driven calls,” says Gale Ridge, an entomologist on the Connecticut Agricultural Experiment Station in New Haven. Ridge has been taking these calls.

Involved readers have reached out to Science Information, too. We shared with Ridge the half dozen images of suspected homicide hornets we acquired. She noticed European hornets, bald-faced hornets (technically yellow jackets) and robber flies. No homicide hornets.

“Within the public thoughts, the hornets are ‘right here,’ ” Ridge says. She patiently explains to her frazzled callers that the hornets are being intercepted practically 3,000 miles away throughout a whole continent.

“The mix of half-listening and overdramatization of the details by the media creates an anxiety-driven stew,” Ridge says. She combats that nervousness by instructing native residents about New England’s bugs, corresponding to European hornets and cicada-killer wasps which are typically mistaken for Asian large hornets. “One creates a contemporary storybook of knowledge on which callers can chill out, really feel comfy and thrive,” she says.
