Through my own inattention, I put coccoons from an EF colony into my EH's (Europeans). They have since hatched and grown. The herd is doing great but I'd like to have colonies of each. I went through one of my bins this afternoon and separated worms that were obviously EH's, mainly were big and still had not developed clitelum.

Is there a simple way to tell the difference between the 2 species? I was pretty disapointed with the numbers of EH's that I KNEW I could ID.
