Worm Found in Bed Actually Harmless Larva or ‘Grub’

A female reader wrote to use having found a critter in her bed. Typically, when we get a letter about a creature in someone’s bed, it turns out to be a carpet beetle larva. So, imagine our surprise when this one wasn’t. Continue reading [...]

Grub in the Basement: May Be(etles) or June Bug

A reader would like help identifying what the worms she’s finding on her basement floor are. From the picture provided, we think that this is a lawn grub, possibly the larva of a June Bug or Masked Chafer Beetle, (Cyclocephala) which are members of the scarab family. The Masked Chafer Beetle larva is a white grub with a dark stripe on its back with a brown head capsule and legs. When full grown, white grubs are about 1 inch (2.5 cm) long grubs and if our reader stretched one out, she'd find it has irregularly arranged spines on the underside of the last body segment (raster). They are commonly found curled in the C shape and are considered agricultural pests, in part because they really enjoy eating the roots under new turf and can kill lawn installations pretty handily. June bugs Continue reading [...]

White Worm is a Grub

A reader just sent us this photo of a cream-colored specimen that he found on a slate patio in a New York City. It had recently rained when he discovered this creature near his dog. His description is great, so we will include it here: "It's white with a brown 'face.' It looks like it has several antennae at the front end. Although it's a pearly white, its rear 25% looks like it contains something dark or black. It ambulates quite nicely." Continue reading [...]

Small White Worm with Brown Head

A reader just sent us a photo on our Facebook page and requested the identification of the creature in it. The picture features a very small worm-like organism with a white body and brown head. We don’t have any information about its behaviors or where it was seen. We aren’t positive what this creature is, but we have eliminated it down to two possibilities. Our first thought is that this specimen is a grub, which is another word for beetle larva. Grubs live in the soil and eat plant roots. They can cause significant damage to trees and shrubs. While grubs have a white body and brown head, they are often much fatter than the creature featured in the photograph. Perhaps this grub is just very young and hasn’t eaten very much yet? Our second idea is that this is pantry moth larva. Continue reading [...]

Grub is Cottonwood Borer Larva

A reader from California contacted us about some cottonwood trees he planted outside of his apartment building. He planted these trees several years ago, but is just now beginning to notice some damage to the trees. After doing some research on the problem he believes the issue might be cottonwood borers. Although he has never seen any of these creatures, he has seen some evidence of their molting. For those who are curious, molting is shedding old skin, hair, or feathers to make room for new growth. Finally, he found a living organism while breaking up some branches. He sent us a photo of the creature he discovered and requested any information we can provide. Continue reading [...]
