Albino dubia!!!

[AdamL8]

I love dubias. My question - can you tell the sex before they are adults? Some of them are more long and narrow and others are more wide. Does that have anything to do with it or is that just individual variation?

You can tell but it doesn't have anything to do with the body shape as far as I've noticed. I originally thought the same thing but it seems to just be the way that some of them develop. It has to do with the segments on the underside right at the rear end. The males will have 2 in the space that a female has 1. You can see this on all sizes of nymphs although it is obviously more difficult the smaller they are. It can also help to have several in front of you so you have at least 1 male and 1 female for comparison. These are not my pictures but they show what I'm talking about.
