Of the Sphinx Moth. Today's quiz question involves metamorphosis of the Sphinx Moth, well - any moth, really. Complete or incomplete? And I'll even give you a hint with this summary. It's all anyone (who isn't an aspiring entomologist) needs to know about insect metamorphosis, in my opinion.
If you said: Catclaw and White Thorn Acacia for yesterday's quiz, you know to watch out for their thorns.
