Scientists can learn a lot about the locusts swarming over Egypt and Israel just by looking at the pictures. Keith Cressman, senior locust forecasting officer for the U.N. Food and Agriculture Organization, is based hundreds of miles away in Rome — but he can tell that these particular bugs may be on their last legs.
"The few good pics I have seen of the locusts show that they are a brick red rather than pinkish," Cressman told NBC News in an email. "Both colors indicate they are immature adults, but the dark color suggests they are old and tired rather than young and hungry. Hence, the infestations arriving in northeast Egypt and Israel will probably come to nothing." That's the good news. The bad news is that other locust swarms could pose a more serious threat to the region's agriculture later this year. To get the details, check out the full story in Cosmic Log.
