The gardens surrounding London's Natural History Museum are being overrun by a miniscule red-and-black insect. The interesting part? The museum's world-class staff of entomologists don't know what it is. The insect has been around since last year, and it remains unclassified. The museum's collections manager commented, "We waited to see if the insect would survive the British winter. It did and it's thriving, so now we had better figure out what it is."
