Tabby

"Tabby" by Winston K. Marks is a science fiction story that tells the tale of a scientific expedition to a remote island that faces an ecological crisis when a flying saucer drops off a swarm of strange, green insects called "Tabby". Told through a series of letters, a scientist named Fred documents how the rapidly multiplying Tabby insects throw the island's ecosystem out of balance, causing an explosion in the population of giant, predatory spiders that have a symbiotic relationship with the insects. Faced with the possibility that the Tabby is an alien weapon designed to disrupt Earth's environment, Fred and his team struggle to understand and contain the invasive species before it's too late, wrestling with the delicate balance of nature and the potentially devastating results of human discovery and meddling.
