Lena, your thread reminded me that a 2007 book (Swallowtail Butterflies: Biology and Ecology of a Few Indian Species by Jagannath Chattopadhyay) states, "Fifth instar [Papilio demoleus] larvae containing no dorsolateral oblique black patches or with faint patch", such as these* . . .

. . . "develop into female butterfly, while the larva having continuous or discontinuous dorsolateral patches", similar to these* . . .

. . . "develop into male. This is a new finding."

Please keep the above in mind when rearing Lime cats, as it would be interesting to know if this assertion can be corroborated outside of India, if at all. Thanks very much to everyone in advance for sharing your results and any discoveries!

Now, I have more reason to rear some Lime butt, Keith.

Lena, I can't offer any advice on sexing Limes, as I have no direct interest in adults (it's the preceding unglamorous 75% that fascinate me), but the abdominal size and rear segment of the butterflies in your photos clearly show that:

P1160833 above (bottom pupa) is a female
P1160839 above (top pupa) is a male
Viewtopic.php?f=37&t=823 is a male
Viewtopic.php?f=37&t=1233 is a female

Four possibilities come immediately to mind:

* Dr. Chattopadhyay's observations or methodology are/is flawed.
* This morphological discovery in India is not widely applicable.
* The gender-based difference is a generalization, not a "rule".
* Your female butterfly was in fact a plainly marked larva, e.g. the right-hand cat in P1140963.
