Terrestrial Planaria FlatwormsUnknown in the North Carolina Piedmont |
Professional landscapers, responding to a demand for lollipop tree scenescapes, accidentally transport terrestrial planaria all over the world. They are now there to stay, changing our ability to sustainably produce food in ways we do not yet understand. If you see one of these here please let us know! | |

Bipalium vagumAs frequently as a grey rat snake is confused with a copperhead, B. vagum is frequently mis-identified as B. kewense by university scholars and nature websites. The North Carolina State University Department of Entomology mis-attributes both the worm and the photographer! Three dark stripes on tan body; central dark stripe much wider than B. kewense. Uninterrupted dark collar behind the head that completely encircles the neck, unlike the interrupted dark patches on B. kewense. Common in Florida in the United States. Thought to prey on snails and slugs. Unknown here. |

Terricola from the British IslesTerrestrial planaria thriving in England, from Australia, New Zealand and other areas, would probably do well here as well, so keep an eye out for them. |
