Okay, so, it would be great if you guys could help me on this topic. I have 5 C. Gemmatus, and I have been trying to count abdominal segments, but it is difficult because they are around 1 cm long. :blink: For the people who have had more experience counting segments, please post your input. Yesterday, I thought there was two guys, but today, I recounted and it seems that they are all male, and now, only one is female. :blink: Your opinion is appreciated. They are numbered. Thanks!

They look like all females to me except for number 5 and 3 which appears to be male. With the last segment being dark it is hard to tell if it is one segment or two. But if that last segment on the end is one big one it is a female.
