wood cockroach and parasite - Parcoblatta

wood cockroach and parasite - Parcoblatta
Epping, Rockingham County, New Hampshire, USA
June 21, 2010
Size: About 7 cm long
I accidentally stepped on this wood cockroach. I looked down at the roach and noticed this worm emerging from its posterior. Does anyone know what kind of parasite this long, skinny worm is? After it wriggled out of the roach it writhed around and flopped around in a somewhat stiff manner.

The lot is wooded, mixed deciduous/coniferous with a river nearby.

It happened the exact way to
It happened the exact way to me too!!!
Except I screamed then took a shoe to the wood cockroach
and when I came back to wipe it up this worm crawled out
of it like a sci-fi movie!
Took the shoe to the worm after it flipped and flopped
for a while, it still wouldn't die, hot still alive
then my husband picked it up with a towel and tore it in half.
We noticed this was the worm we found outside in the morning 2X after a rainfall at night.

Moved from ID Request.

Thanks for the information Blaine.

Sorry I can't help with ID-ing but just had to say I would've freaked! You are brave to get photos of such an occurrence!

Actually.. as far as ID-ing, I'd say its some kind of Nematode but thats just a guess...

thanks WanderingMogwai
I don't think I've seen anything quite like this before. I have seen these worms twice before once free swimming in my birdbath and another one free swimming in a tarp that filled with rain water. But this is the first time I've seen one emerge from another organism.

Its some kind of nematamorh also known as gordian worms, nasty little suckers, the adults are free living and the larvae usually infect crickets or grasshoppers. Some actually live through the adult exiting the body cavity.

Thanks for the ID and informa
Thanks for the ID and information Kingswede21. I did a bit of research and it looks as though people and pets don't need to worry about these worms, only invertebrates.
