Explanation of Names
Apparently from Latin manduc, chew (1), verb manducare to chew (2). Presumably refers to the feeding of the caterpillar.
10* Manduca species are found in America north of Mexico(3)
* Species not yet in the guide: M. albiplaga (single adventitious record in KS)
Life Cycle
Molting is initiated when the insect gets to a certain weight.(4)
Metamorphosis occurs when juvenile hormone are switched to ecdysteroids. This is related to head size at the beginning of the larval stage. If the head width is over 5mm, pupation occurs at the next molt when the insect weighs around 5g. It isn't known how the insect assesses this or how the info is transmitted.(4)
