We received an interesting question from a reader through the All About Worms Facebook page about a “greenish grey worm” that his cat found on his lawn. The worm (or probably larva) is “2-3 inches long and had rings around it so he looked like a bunch of inter-tubes stacked on each other.” However, the defining characteristic of the creature is that it made noise. The reader was wondering what kind of worm or larva he (or technically his cat) found.

A reader wrote to us recently to inquire about some gross “things” she found in her yard. The things might more precisely be described as fat and white with brown heads, and the reader was wondering if she found some sort of worm or larvae. We are basically certain she found grubs, which are also called “lawn grubs” or “grub worms” (even though they are larvae), and below we provide a little more information about these creatures. The reader also mentioned that she is concerned about the “dangers they may pose for humans and pets,” so we’ll address this matter as well.

A reader wrote to us a few days ago about some large, plump white worms that he found in a mulch pile on his lawn. The reader thought they were grubs, which are often called “grub worms” or “grubworms” (even though they are actually larvae), but thought that they might be too big to be grubs, in part based on information he read on this website. The creatures our reader found are in fact quite large – they are about three inches (7.5 centimeters) long and one inch (2.5 centimeters) wide – but they nevertheless appear to be grubs. Did our reader find grubs in the mulch pile on his lawn, or are the creatures he found too big to be grubs?
