So my T.sinensis ooth hatched two weeks ago and the few nymphs I have kept have undergone their first instar. All of the nymphs except one have doubled in size. One nymph has grown just slightly bigger than before it molted but has not doubled in size like the others. My question is this: could this smaller nymph possibly be a male? I know that females are bigger than males and all of the other nymphs grew proportionately after their instar except this one. Whatever it is it's more outgoing than the others and it walks right up to the magnifying glass and say "hello" while swaying back and forth and turning it's head from side to side. It is one that I will be definitely keeping an eye on as it has really piqued my curiosity as to it's gender. Thanks to any and all who can educate me on this one.
