Found this worm hanging in an oak tree on July 20 by a silk thread. It is 5-6 inches long and iridescent in the sunlight. Can’t find any info about it, hoping you can help. Thanks.

Blue Worm: Hoax or Real???

Dear Carole,
We have no idea what this is, but it does not look natural and it appears to have been hung by a human.

So sorry to bother you.  I came to the same conclusion you did  this afternoon as I got more curious and decided to get a step ladder out and touch it.  Turns out it is a fishing lure.  I still have no idea how it got into a tree in my back yard.  My yard is fenced with no gate and I have several dogs (they are friendly).  I hung a chandelier on the next branch over not long ago and the worm was not there then.  I live alone and do not fish.  It is now a new mystery.  Thank you so much for your time.  A friend sent me to your site…it is really interesting.  Again sorry for sending you on a wild goose chase.   Carole

Don’t worry Carole.  Your submission prompted a robust dialog in our comment section and led to some nice links of “real” blue worms in various parts of the world.

    I immediately thought “fishing lure”, but then remembered reading about giant earthworms. I looked up “blue earthworms” and found a species, Megascolex coeruleus. Here are a few links to images. The giant blue earthworms are native to Sri Lanka, not Tennessee. Megascolex are bioluminescent: http://eol.org/pages/3126682/overview
    This is a mystery.
