Jim Hill, Hancock County Extension Director forwarded the photos below that show the remnants of a night of spiders gone wild. On occasion we hear reports that "my lawn is covered with webs." Here are the photos to prove it. We cannot determine the species of spider from the web and by the time the dew has dried in the morning the recently hatched spiderlings that made the mess have either died or moved on.
We don't have a good explanation for more-than-usual numbers of spiderlings. We know it happens in fields, meadows and lawns at various times of the year, though more often in fall than at other times. The good news is that the spider webbing is not a problem, the phenomenon is short-lived and the situation passes with no need for treatment or attention other than to marvel at the site while you have the chance.
