Q: My neighbor has hundreds of small spider webs all over his lawn after a rain. Any idea what those webs are?
A: They are probably the webs of funnel weaver spiders. They are completely harmless and indeed eat aphids, moths, chinchbugs and other lawn pests. When prey lands on the wide sheet of the spider web, the spider darts out to grab it and bring it back to a the narrow funnel for consumption. One old-fashioned saying is that when there is dew on their webs in the morning, it will be a beautiful day.
