Commentary

Thank you for your report! Bipalium adventitum is quite likely, though there are other flathead planarians in Oregon with similar characteristics. There are currently no actions being taken about these worms, but your observation helps us understand their distribution in the state and becomes a resource for future work. Best,
-Lindsey
