Black Worm or Caterpillar with Red Dots

We received an interesting and faintly poetic question the other day about a black “worm” that has a red dot on each body segment. Here is her entire question: “Middle of May, Northern California, Black worm about two inches long, seems hairless has what appears to be thin covering of bristles, red dots on each segment, racing across my deck floor. Please identify.” Unfortunately, no picture was submitted along with the question, so this description is all we have to work with. Obviously, this limits our ability to offer a confident suggestion, but we’ll do what we can.

Black Caterpillars with Yellow Undersides

A reader wrote to us via the All About Worms Facebook page recently about some black caterpillars in her backyard. “Some” black caterpillars probably doesn’t quite capture the situation, as the reader reports that they are “all over” her backyard. The black caterpillars are “yellow underneath,” although you can’t really see this in the picture the reader submitted. The reader is wondering what these black caterpillars in her backyard are, if they are even caterpillars.

A Spiky Caterpillar with an Orange Stripe

A very helpful reader wrote to us in reference to an article we published last year. It was an article about what a curious reader thought was a worm, but was in fact probably a caterpillar based on the physical description we were sent. The caterpillar was long, thick, and spiky. It was also primarily black, although the caterpillar had white dashes on its body and an orange stripe down its back. The reader who more recently wrote to us sent us a picture of what seems like the same caterpillar. We didn’t have a picture of the spiky caterpillar in the old article, so the reader sent us one. Thanks!

Furry Worms that are Black, Gold, and White

We recently received a very straightforward question from a reader: “I found a worm, it is furry, black, gold and white. What is it?” While direct and simple language has its virtues (think of Hemingway), it can make worm identification difficult. Regardless, we’re always interested in investigating a worm-related question, so we’ll try our best to identify this multicolored furry creature.
