Dear Mr. Bugman,
I’ve seen tons of caterpillars around my house recently but I’ve never seen any like this one. What type of caterpillar is this??

Milkweed Tussock Moth Caterpillar

Milkweed Tussock Moth Caterpillar

Dear Samantha,
Do you have milkweed plants growing near your house?  We believe this is a Milkweed Tussock Moth Caterpillar,
Euchaetes egle, and it feeds on milkweed.  Though it seems lighter in color to individuals on our site, it does match this BugGuide image pretty closely.

That looks exactly like it, thank you!!

Fall Webworms

Fall Webworms

These are Fall Webworms, Hyphantria cunea.  According to BugGuide:  “Weblike tents in branch tips where clusters of caterpillars strip foliage (by contrast, eastern tent caterpillar nests are built in tree crotches)” and “Larvae feed on foliage throughout their development, and secrete silk which they spin into small webs. As they grow, they enlarge the webs, which can sometimes enclose the entire tree. Even severe infestations have little impact on trees because the damage occurs near the end of the annual growing season. Except in the case of ornamental trees, control is seldom necessary because the damage is generally of aesthetic rather than economic importance.”  BugGuide also notes:  “About 120 species of hardwood trees have been recorded as larval hosts in the north, common hosts include alder, apple, ash, birch, Box-Elder (Acer negundo), cherry, elm, mulberry, poplar, willow in the south, common hosts include ash, hickory, maple, mulberry, oak, pecan, poplar, redbud, sweetgum, walnut, willow; preferences for different host plant species appear to be regional and seasonal.”

Could this be a silver spotted tiger moth caterpillar? I’ve read they are poisonous but the Boy Scout leader said this one wasn’t. It was found near Guerneville, CA. There were coastal redwoods, Douglas firs and Bay Laurels in the area.

Possibly Silver Spotted Tiger Moth Caterpillar

Possibly Silver Spotted Tiger Moth Caterpillar

Dear Toni,
We agree that this might be the Caterpillar of a Silver Spotted Tiger Moth,
Lophocampa argentata, based on this and other BugGuide images.  According to BugGuide:  “Note of Caution: Like several kinds of wooly-bear-type caterpillars, these have venomous, stinging hairs, which can cause a burning sensation and/or a rash in sensitive people- look, but don’t touch!”  We believe the key words are “sensitive people” meaning most folks, including tough, young children, are not affected.

Dear Bugman, what are these little guys?They were on a wall inside my house this morning. At first I thought they were ants buy they are about half the size. They appear to be some kind of worm – with legs? Until I took the picture I couldn’t see the legs at all. They weren’t really moving, except to rear up at me when I got close.

Probably Woolly Bear Hatchlings

Probably Woolly Bear Hatchlings

Dear Squirmy Wormies,
These are newly hatched Caterpillars, probably from the subfamily Arctiinae, the Tiger Moths.  The caterpillars of Tiger Moths are frequently called Woolly Bears because of their furry appearance.

I was searching in my yard for any type of bug I could possibly find, so I picked up and old pipe, tipped it over and out rolled a black and orange fuzz ball! I was very exited by this, because I love caterpillars, which I am pretty sure this is. I think it is a pretty common type. Pretty please with cherry’s on top help me identify it!

Woolly Bear

Woolly Bear

Dear Gracie,
This Woolly Bear is the caterpillar of the Isabella Tiger Moth.  According to BugGuide:  “The second brood overwinters as a caterpillar and pupates in Spring.”
  That means your caterpillar should make a cocoon very soon.

Dear Daniel,
Thank you very much for writing me back! I am looking very forward to seeing the cocoon. At first when I found the caterpillar I was very worried it was dead, because it wasn’t moving. It took a little while for it to do anything, but when it did I was very exited! Thanks again!
