An agriculture specialist believed the insects belonged to the Pyralidae family, a group with thousands of species worldwide, Grogan said. But the expert couldn't identify it further.

The Smithsonian expert later identified the species and said it was the first time the insect's larvae or pupae had been collected, the release says.

It isn't clear where the sighting was in 1912, the year the insect was first described, Grogan said in an email.

Grogan added that the moths found at the airport were "disposed of via steam sterilization."

A type of moth last seen more than a century ago was discovered in a traveler’s luggage at the Detroit airport last year, officials said Monday.

A Smithsonian Institution expert identified the insect as Salma brachyscopalis Hampson, a moth last seen in 1912, Kris Grogan, a spokesperson with Customs and Border Protection, said in an email.

Larvae and pupae from the moth were found in September at Detroit Metropolitan Airport in a bag arriving from the Philippines, Grogan said in a news release. The insects were inside seed pods that the passenger claimed were for medicinal tea, Grogan said.

Despite the hurdles, using the technology to bring back species is still worth doing, says Ben Novak, lead scientist at Revive & Restore, a nonprofit that uses genetic engineering for conservation projects. He plans to apply Gilbert and colleagues’ analysis to his own work on the passenger pigeon, which went extinct in 1914. There are possible solutions for how to capture some of the missing data, he says, but the fact that some data will always be missing is a limitation that de-extinction scientists have already come to terms with.

“The reference assembly problem will always be a barrier to de-extinction,” Novak says. “Anyone pursuing de-extinction has to settle on the fact that we want to get as close as we can to something that fools the environment.”

Gilbert doesn’t think it’s likely that anyone will try to de-extinct a rat. But he says that what the team has demonstrated could prove useful for people working on even more ambitious projects, like bringing back the woolly mammoth. The divergence between the Norway brown rat and the extinct Christmas Island rat, for example, is similar to that between the Asian elephant and woolly mammoth.

“By doing these kinds of analyses, which is not hard to do, you can at least come up with the what will you get, what will you not get, and you can use that to decide is it worth doing,” Gilbert says.

Some tellings of the Schieffelin starling origin story note these earlier introductions but suggest that those birds failed to survive. However, wild starlings were caught in Massachusetts in 1876, far from any of the documented introductions. Likewise, there is a record of wild starlings in New Jersey in 1884. And who knows how many birds truly survived in nature beyond human notice, the researchers argue.

“From the perspective of an invasion biologist, most invasions come from multiple introductions,” said Natalie Hofmeister, a doctoral candidate at Cornell University.

This is something both Iredale and Ray support.

"Whether they are 'aware' of the influences driving their decision-making and the personal consequences of their stinging behavior is not obvious," Ray said.

Iredale agreed that bees are unlikely to be aware of the consequences of stinging a human. "I think knowledge of one's mortality might be a burden that only highly derived organisms, such as primates, experience," Iredale said. "But, if the bees are aware, I genuinely think they would sacrifice themselves willingly for the good of the colony."

To bee, or not to bee
Given the dire fate that awaits a honeybee once it stings a human or other thick-skinned mammal, is there any chance the bee is aware of what the outcome will be? Are they cognisant of the fact that once their stinger pierces the skin, they are essentially signing their own death certificate?

"I do not think that honeybees understand that they are going to die when they sting, but under the right circumstances, they are very willing to give up their lives for defense of the colony," Naeger said. "When it comes to protecting the colony or making sure that genes are passed to the next generation, the instincts that drive those behaviors clearly outweigh any concern that the bees might have for their individual selves."
