An unusually large influx of tiny insects called aphids have been sucking on Dallas-area pecan trees this summer.

After they've had their fill, they excrete the waste out their back ends and onto cars, driveways and sidewalks. "Texas is covered in a sticky, icky goo," declared a Dallas Morning News headline. Other news outlets offered tips on how to clean up the mess.

It's not just Texans who should be grossed out. Scientists who study the relationship between insects and plants have long predicted that a warming climate would benefit aphids and other plant-eating pests. The Texas drought, which occurs as the state experiences rising temperatures under the influence of climate change, is just one example. Elsewhere, surging populations of plant-eating insects are disrupting farms and the food supply chain, causing problems far more serious than sticky windshields.
